Introducción: El ictus isquémico representa la tercera causa de mortalidad en el mundo y la primera causa de discapacidad. Objetivos: Describir los efectos beneficiosos de la prescripción de las estatinas en la prevención primaria, secundaria y terciaria del ictus isquémico. Métodos: Se realizó una revisión bibliográfica sobre la prescripción de estatinas en la prevención primaria, secundaria y terciaria del ictus isquémico. Se revisaron más de 400 artículos publicados en PubMed, Cochrane y Medline. Conclusiones: El empleo de estatinas disminuye la mortalidad en la prevención primaria y secundaria, se utiliza precozmente en la fase aguda (prevención terciaria), disminuye el área infartada, existe una mejoría clínica y disminuyen los reactantes de la fase aguda como la proteína C reactiva.

Introduction: Ischemic stroke represents the third cause of mortality worldwide and the first cause of disability. Objective: To describe the beneficial effects of the prescription of statins in the primary, secondary and tertiary prevention of ischemic stroke. Methods: A bibliographic review on the prescription of statins in the primary, secondary and tertiary prevention of ischemic stroke was carried out. More than 400 articles published in MEDLINE/PubMed and Cochrane were reviewed. Only 50 articles met the selection criteria, which were published from May 2021 to June 2022. Conclusions: The use of statins decreases mortality in primary and secondary prevention. If they are used early in the acute phase (tertiary prevention), the infarcted area decreases, there is clinical improvement and acute phase reactants such as C-reactive protein decrease.

Estatinas, una alternativa en el tratamiento de la COVID-19 / Statins, an Alternative in the Treatment of COVID-19

Resumen Las estatinas son ampliamente utilizadas para el control de los niveles de colesterol en pacientes con hipercolesterolemia, lo cual permite prevenir enfermedades cardiovasculares. Además de controlar la síntesis endógena de colesterol, las estatinas tienen efectos pleiotrópicos diversos, como son las propiedades antiinflamatoria, antioxidante y de inmunomodulación. La enfermedad causada por el virus SARS-CoV-2 (COVID-19) provoca una tormenta de citocinas que contribuye a la generación del síndrome respiratorio agudo, que puede llevar a cuadros graves de esta enfermedad e incluso a la muerte del paciente. Diversos estudios realizados en enfermos con COVID-19 que recibieron estatinas, antes o durante el curso de la enfermedad, registraron cuadros menos graves, estancias hospitalarias más cortas y menor mortalidad. El beneficio de las estatinas en la COVID-19 debe ser explorado más ampliamente, ya que potencialmente pueden contribuir al control de esta pandemia que ha postrado a la humanidad.

Abstract Statins are widely used to control cholesterol levels in patients with hypercholesterolemia, which helps prevent cardiovascular diseases. In addition to controlling endogenous cholesterol synthesis, statins have diverse pleiotropic effects, such as anti-inflammatory, antioxidant, and immunomodulatory properties. The disease caused by the SARS-CoV-2 virus (COVID-19) causes a cytokine storm that contributes to the generation of acute respiratory syndrome, which can lead to severe symptoms of this disease and even the death of the patient. Various studies carried out on patients with COVID-19 who received statins, before or during the disease, registered less severe symptoms, shorter hospital stays and lower mortality. The benefit of statins in COVID-19 should be explored more widely, as they can potentially contribute to the control of this pandemic that has devastated humanity.

Impacto do uso sistêmico de estatinas e de bisfosfonatos nos tecidos periodontais: revisão narrativa / Impact of the systemic use of statins and bisphosphonates in the periodontal tissues: narrative review

Introdução: A literatura tem apontado uma possível relação entre diversas condições sistêmicas e as doenças periodontais. Dentro das doenças sistêmicas que podem gerar o uso crônico de medicamentos, com potencial associação com as doenças periodontais, destacam-se a hipercolesterolemia e o uso de estatinas; e as doenças do metabolismo ósseo e o uso de bisfosfonatos. Objetivo: Dessa maneira, o presente estudo objetivou revisar a literatura sobre o efeito das estatinas e dos bisfosfonatos nos parâmetros clínicos e radiográficos periodontais de indivíduos adultos. Resultados: Apenas estudos observacionais em humanos foram incluídos. Um estudo mostrou que, em pacientes que apresentam doença periodontal e usam estatina, houve 37% menos bolsas periodontais (profundidade de sondagem ≥4mm) quando comparadas aos que não utilizam a medicação, além de apresentarem menor índice de carga inflamatória e menor perda de inserção clínica. Em relação aos bisfosfonatos em indivíduos com doenças que envolvem o metabolismo ósseo, sugere-se que a utilização do fármaco tem obtido resultados positivos nos parâmetros periodontais, como menores sinais clínicos de inflamação gengival, menor profundidade de sondagem, menor perda de inserção clínica e maior nível de osso alveolar, quando comparados aos que nunca realizam essa terapia. Conclusão: Dessa forma, as estatinas e os bisfosfonatos apresentam efeitos promissores, em pacientes sob tratamento para suas respectivas condições sistêmicas, na melhoria dos parâmetros periodontais, porém é importante salientar que são necessários mais estudos sobre o assunto para melhor entender os reais efeitos a longo prazo do uso desses fármacos.(AU)

Introduction: The literature showed a possible relationship between several systemic conditions and periodontal diseases. Within the systemic diseases that can generate the chronic use of these drugs, potentially related with periodontal diseases, it may be cited the hypercholesterolemia and the use of statins; and bone metabolism diseases and the use of bisphosphonates. Objective: In this sense, the present study aimed to review the literature about the effect of statins and bisphosphonates in the periodontal parameters of adults individuals. Results: Only observational studies in humans were included. A study showed that, in patients with periodontal disease and users of statins, there 37% fewer periodontal pockets (probing depth ≥4mm) when compared to those who do not use the medication, as well as having a lower rate of inflammatory burden and less loss of clinical insertion. Regarding the bisphosphonates in individuals diagnosed with diseases involving bone metabolism, it was suggested that the use of the drug has obtained positive results in periodontal parameters, such as a greater absence of plaque, less clinical signs of gingival inflammation, less probing depth, lower level of clinical insertion and higher level of alveolar bone when compared to those who never undergo this therapy. Conclusion: Thus, statins and bisphosphonates have promising effects in patients under treatment for their respective systemic condition in improving periodontal parameters, but it is important to emphasize that further studies on the subject are needed to better understand the long-term effects of the use of these drugs.(AU)

ABSTRACT INTRODUCTION: Stroke is one of the most prevalent cardiovascular events in the world, in Colombia it is the second cause of death and first in disability. One of the most important risk factors to consider is cholesterol control, the reduction of LDL-C and cholesterol levels, mainly through treatment with statins and other lipid-lowering drugs. MATERIALS AND METHODS: The most relevant information on the use and benefits of this treatment and some additional considerations have been collected in this narrative review of the literature. CONCLUSION: The results of this narrative review show the protective effect of this therapy when it is possible to reduce LDL-C and cholesterol levels, in addition to other therapies such as ezetimibe or PSCK9 inhibitors. On the other hand, studies mention possible beneficial effects in the context of stroke but more clinical trials are required.

Prescription of statins according to the ASCVD estimator at Pablo Arturo Suarez Hospital, March 2021 to February 2022 / Prescripción de estatinas según el estimador ASCVD en el Hospital Pablo Arturo Suárez, marzo 2021 a febrero 2022

Worldwide, the leading cause of death is cardiovascular disease. The study details the prescription of statins at the Pablo Arturo Suarez Hospital in Ecuador between March 2021 and February 2022 following the ASCVD risk scale of the American College of Cardiology and the American Heart Association. There are 563 people in this cross-sectional and retrospective study: 70% women, 30% men, 93.30% mestizos, 48.10% diabetics, 62.30% hypertensives, and 18.70% smokers. 26.10% of all patients received statins, with simvastatin being the most common (96.60%). The mean cardiovascular risk in the general population was 15.52 ± 14.51%, 44.99% of subjects had a risk lower than 7.50%, and 29% had a risk higher than 20%, with a statistically significant difference (p<0.001) according to sex. The study determined that 58.60% of the population received a statin or an inadequate dosage.

A nivel mundial, la principal causa de muerte es la enfermedad cardiovascular. El estudio detalla la prescripción de estatinas en el Hospital Pablo Arturo Suárez de Ecuador entre marzo de 2021 y febrero de 2022, siguiendo la escala de riesgo ASCVD del Colegio Americano de Cardiología y la Asociación Americana del Corazón. Son 563 personas en este estudio transversal y retrospectivo: 70% mujeres, 30% hombres, 93.30% mestizos, 48.10% diabéticos, 62.30% hipertensos y 18.70% fumadores. El 26.10% de los pacientes recibía estatinas, siendo la simvastatina la más frecuente (96.60%). El riesgo cardiovascular medio en la población general fue de 15.52 ± 14.51%, el 44.99% de los sujetos tenía un riesgo inferior al 7.50%, y el 29% tenía un riesgo superior al 20%, con una diferencia estadísticamente significativa (p<0.001) según el sexo. El estudio determinó que el 58.60% de la población recibía una estatina o una dosis inadecuada.

¿Es el colesterol no-HDL un indicador de riesgo cardiovascular en las personas con diabetes mellitus? / Is non-HDL cholesterol a risk marker for cardiovascular atherosclerotic disease in diabetes mellitus?

La diabetes mellitus tipo 2 (DM2) es un factor de riesgo cardiovascular (FRCV) mayor. La DM confiere dos a cuatro veces más riesgo cardiovascular (RCV). El riesgo es aún más elevado en el paciente con DM2 que ha sufrido un infarto agudo de miocardio (IAM) o un accidente cerebrovascular (ACV). La dislipidemia de la DM2 consiste en triglicéridos elevados de ayuno, con mayor excursión posprandial, bajos niveles de HDLc, y alteraciones cuantitativas y cualitativas de LDLc y HDLc. El control glucémico apropiado en DM2 mejora en gran medida las alteraciones lipoproteicas. La terapia hipolipemiante es clave para reducir el RCV en la DM2. La reducción del RCV que se consigue con estatinas se basa en la reducción del LDLc y sus efectos pleiotrópicos. En pacientes que persisten con el perfil lipídico alterado, a pesar de dosis altas de estatinas, se debe considerar el agregado de otros agentes hipolipemiantes para reducir las lipoproteínas aterogénicas.

Type 2 diabetes (T2D) is a major cardiovascular risk factor (CVRF). Diabetes confers two to four times more cardiovascular risk (CVR). The risk is even higher in patients with T2D who have suffered an acute myocardial infarction (AMI) or cerebrovascular accident (CVA). The dyslipidemia of T2D consists of high fasting triglycerides, with greater postprandial excursion, low levels of HDLc and qualitative alterations of LDLc and HDLc. Appropriate glycemic control in T2D greatly improves lipoprotein abnormalities. Lipid-lowering therapy is key to reducing CVR in T2D. The CVR reduction achieved with statins is based on the reduction of LDLc. In patients who persist with an altered lipid profile despite highdose statins, the addition of other lipid-lowering agents to reduce atherogenic lipoproteins may be considered.

Analysis of serum cholesterol, statins and atherosclerotic plaque in ruptured and unruptured intracranial aneurysm / Análise de colesterol sérico, estatina e placa aterosclerótica em aneurisma intracraniano roto e não roto

Introduction Intracranial aneurysm (IA) is a major healthcare concern. The use of statin to reduce serum cholesterol has shown evidence to reduce cardiovascular risk in various diseases, but the impact on IA has not been described. This study aims to determine whether statin use, and serum cholesterol levels interfere with outcomes after IA event. Methods A cohort of patients with IA was analyzed. Patients social and demographics data were collected.Modified Rankin scale (mRS) score after 6months of follow-up was the endpoint. The data regarding statins use, presence or not of atherosclerotic plaque in radiological images and serum cholesterol of 35 patients were included in our study. Linear regression models were used to determine the influence of those 6 variables in the clinical outcome. Results The prevalence of atherosclerotic plaque, high cholesterol and use of statins was 34.3%, 48.5%, and 14.2%, respectively. Statins and serum cholesterol did not impact the overall outcome,measured by mRS after 6 months (p>0.05), but did show different tendencies when separated by IA rupture status. Serum cholesterol shows na important association with rupture of aneurysm (p»0.0382). High cholesterol and use of statins show a tendency for worse outcome with ruptured aneurysm, and the opposite is true for unruptured aneurysm. The presence of atherosclerotic plaques was not related with worse outcomes. Conclusions Multiple and opposite mechanisms might be involved in the pathophysiology of IA. Ruptured aneurysms are associated with higher levels of serum cholesterol. Serum cholesterol and statins use were not correlated with worse outcomes, but further studies are important to clarify these relationships.

Introdução Aneurisma intracranial (AI) é uma grande preocupação para a saúde. Evidências apontam que o uso de estatina para reduzir o colesterol sérico diminui o risco cardiovascular em diversas doenças, mas o impacto em AI ainda não foi descrito. Este estudo almeja determinar se o uso de estatina e o nível sérico de colesterol interferem no desfecho clínico após a ocorrência de AIs. Métodos Uma coorte de pacientes com AI foi analisada. Os dados sociodemográficos dos pacientes foram coletados. Ao final de 6 meses de acompanhamento, aplicou-se a escala modificada de Rankin (mRS). Os dados sobre uso de estatina, existência de placa aterosclerótica em imagens radiológicas, e colesterol sérico de 35 pacientes foram incluídos no estudo. Modelos de regressão linear foram usados para determinar a influência dessas 6 variáveis nos desfechos clínicos. Resultados A prevalência de placa aterosclerótica, colesterol elevado, e uso de estatina foram respectivamente 34,3%, 48,5% e 14,2%. Estatina e colesterol sérico não impactaram nos desfechos medidos pela mRS em 6 meses (p > 0,05), mas mostraram diferentes tendências quando separados pelo estado de ruptura do AI. Colesterol sérico apresenta uma importante associação com ruptura de aneurisma (p » 0,0382). Colesterol elevado e uso de estatinas representam uma tendência a piores desfechos para aneurismas rompidos, e o oposto é verdade para os não rompidos. A presença de placa aterosclerótica não está relacionada com piores resultados. Conclusões Mecanismos múltiplos e opostos podem estar envolvidos na patofisio logia do AI. Aneurismas rompidos estão associados com maiores níveis de colesterol sérico. Colesterol sérico e estatinas não foram correlacionados com piores desfechos, mas mais estudos são importantes para clarificar a relação entre esses fatores

Tratamiento farmacológico en la restricción del crecimiento fetal: revisión de la bibliografía / Pharmacological management for fetal growth restriction: literature review

Resumen OBJETIVO: Explorar las diferentes estrategias de tratamiento farmacológico de la restricción del crecimiento fetal propuestas a lo largo del tiempo. METODOLOGÍA: Revisión cuasi-sistemática de la evidencia científica histórica disponible acerca del tratamiento médico descrito para la atención de mujeres embarazadas con restricción del crecimiento fetal. RESULTADOS: Entre los tratamientos médicos descritos para tratar la restricción del crecimiento fetal, los donadores de óxido nítrico, las estatinas y la aspirina asociada con omega 3, han tenido desenlaces no consistentes en estudios con limitado tamaño de muestra. Por lo que se refiere a los inhibidores de la 5-fosfodiesterasa, el sildenafilo no se ha asociado con un aumento de la velocidad de crecimiento fetal pero sí con alarmas respecto de su seguridad debidas al incremento de los casos de hipertensión pulmonar fetal y mortalidad perinatal. Por su parte, el tadalafilo ha mostrado desenlaces iniciales favorables y se esperan estudios con mayor tamaño de muestra que permitan emitir recomendaciones claras con respecto a su indicación. También se esperan los desenlaces de estudios clínicos en curso, para definir la indicación de la heparina de bajo peso molecular en este escenario en virtud de sus prometedores resultados iniciales. Los procedimientos más invasivos, como la inyección de factor de crecimiento endotelial vascular y la plasmaféresis, permanecen en estudio como propuestas terapéuticas por los resultados de estudios preclínicos y clínicos con pocos pacientes. CONCLUSIÓN: Por ahora, ninguna estrategia farmacológica propuesta ha conseguido generar recomendaciones fuertes para su indicación; sin embargo, se esperan nuevos estudios con alta calidad metodológica que generen evidencia científica lo suficientemente contundente para recomendar su indicación.

Abstract OBJECTIVE: To explore the different pharmacological treatment strategies for fetal growth restriction proposed over time. METHODOLOGY: Quasi-systematic review of the available historical scientific evidence on the medical treatment described for the care of pregnant women with fetal growth restriction. RESULTS: Among the medical treatments described to treat fetal growth restriction, nitric oxide donors, statins, and aspirin associated with omega-3 have had inconsistent outcomes in studies with limited sample size. As for 5-phosphodiesterase inhibitors, sildenafil has not been associated with an increase in fetal growth velocity, but there have been alarms regarding its safety due to the increase in cases of fetal pulmonary hypertension and perinatal mortality. On the other hand, tadalafil has shown favorable initial outcomes and studies with a larger sample size are awaited to issue clear recommendations regarding its indication. The results of ongoing clinical studies are also awaited to define the indication of low molecular weight heparin in this setting, given its promising initial results. More invasive procedures, such as vascular endothelial growth factor injection and plasmapheresis, remain under study as therapeutic proposals due to the results of preclinical and clinical studies with few patients. CONCLUSION: For now, no proposed pharmacological strategy has managed to generate strong recommendations for its indication; however, new studies with high methodological quality are expected to generate scientific evidence strong enough to recommend its indication.

Are statins a risk factor in patients with atherosclerosis? / ¿Son las estatinas un factor de riesgo en pacientes con aterosclerosis?

SUMMARY: Statins inhibit cholesterol synthesis, but also have other pleiotropic effects. There are indications that they affect macrophage survival trough the regulation of apoptosis. We analyzed 50 samples of aortic wall, selected based on statins in patients' therapy (n=25, Th-S group) or statin-free therapy (n=25, Th-nonS group). Each group had 5 samples of healthy aortic tissue, 10 samples of mild and 10 samples of severe atherosclerotic changes in aortic wall. Tissue was stained with hematoxylin-eosin and immunohistochemical methods (anti-Bcl-2 antibody). Presence of Bcl2-positive macrophages (Bcl-2+ MP) was determined semiquantitatively, and data were processed in Microsoft Excell and IMB SPSS 23 Statistics. 60 % of patients in the Th-S group had a mild increase of Bcl-2+ MP The use of statins leads to a significantly more frequent increase in Bcl2+ macrophages in the intima of the healthy aortic tissue. Analysis of all aortic samples with pathohistological diagnosis showed that statin therapy was statistically significantly more often leading to a markedly increased presence of Bcl-2+ MP. In the media, all samples of the Th-S group have a mild increase of Bcl-2+ MP, and in adventitia 40 % of patients. The use of statins more often leads to a markedly increased presence of Bcl-2+ MP in aortic tissue with diagnosed mild and severe atherosclerosis. In samples of severe atherosclerosis, statins lead to a markedly increased presence of Bcl-2+ MP in the parts of the plaque towards the intima and towards the media. Statins lead to an increased presence of Bcl-2+ macrophages, prolong their life, both in healthy and atherosclerotic altered aortic tissue. This indicates potentiation of inflammation and damage to the aortic wall, and calls into question the positive effect of statins on the aortic wall with atherosclerosis.

RESUMEN: Las estatinas inhiben la síntesis de colesterol, pero también tienen otros efectos pleiotrópicos. Hay indicios de que afectan la supervivencia de los macrófagos a través de la regulación de la apoptosis.Se analizaron 50 muestras de pared aórtica, seleccionadas en base a estatinas en tratamiento de pacientes (n=25, grupo Th-S) o en tratamiento libre de estatinas (n=25, grupo Th- nonS). Cada grupo tenía 5 muestras de tejido aórtico sano, 10 muestras de cambios ateroscleróticos leves y 10 muestras de cambios ateroscleróticos severos en la pared aórtica. El tejido se tiñó con hematoxilina-eosina y métodos inmunohistoquímicos (anticuerpo anti-Bcl-2). La presencia de macrófagos positivos para Bcl2 (Bcl- 2+ MP) se determinó semicuantitativamente y los datos se procesaron en Microsoft Excell e IMB SPSS 23 Statistics. El 60 % de los pacientes del grupo Th-S tuvo un aumento leve de Bcl-2+ MP. El uso de estatinas conduce a un aumento significativamente más frecuente de macrófagos Bcl2+ en la íntima del tejido aórtico sano. El análisis de todas las muestras aórticas con diagnóstico anatomopatológico mostró que la terapia con estatinas fue significativamente más frecuente desde el punto de vista estadístico, lo que condujo a una presencia marcadamente mayor de Bcl-2+ MP. En los medios, todas las muestras del grupo Th-S tienen un leve aumento de Bcl-2+ MP, y en adventicia en el 40 % de los pacientes. El uso de estatinas con mayor frecuencia conduce a una presencia marcadamente mayor de MP Bcl-2+ en el tejido aórtico con aterosclerosis leve y grave diagnosticada. En muestras de aterosclerosis severa, las estatinas conducen a una presencia aumentada de Bcl-2+ MP en las partes de la placa hacia la íntima y hacia la media. Las estatinas conducen a una mayor presencia de macrófagos Bcl-2+, prolongan su vida, tanto en tejido aórtico sano como aterosclerótico alterado. Esto indica la potenciación de la inflamación y el daño a la pared aórtica y pone en duda el efecto positivo de las estatinas en la pared aórtica con aterosclerosis.

Uso de agentes hipolipemiantes y cumplimiento de metas terapéuticas en pacientes de alto riesgo cardiovascular en la República Argentina / Use of Lipid-Lowering Agents and Therapeutic Goal Achievement in Cardiovascular High-Risk Patients in Argentina

RESUMEN Introducción: Uno de los pilares fundamentales para la reducción del riesgo cardiovascular en pacientes en prevención secundaria es el correcto manejo del tratamiento hipolipemiante. Las estatinas en altas dosis, el ezetimibe, y más recientemente los inhibidores de PCSK9 (iPCSK9) son las principales herramientas farmacológicas con las que contamos para que estos pacientes cumplan metas terapéuticas de colesterol LDL (C-LDL). A pesar de la contundente evidencia a favor de estas terapéuticas, existe una gran subutilización de las mismas a nivel mundial, con bajos niveles de adherencia e inercia terapéutica. En Argentina existe escasa evidencia sobre la calidad del tratamiento hipolipemiante, y qué porcentaje de pacientes en prevención secundaria se encuentran con un perfil lipídico controlado acorde a guías nacionales e internacionales. Material y métodos: Diseñamos un estudio de corte transversal en pacientes en prevención secundaria de eventos cardiovasculares incluidos de forma prospectiva, consecutiva y multicéntrica en hospitales de la República Argentina que poseen sistema de Residencia Médica afiliados al Consejo Argentino de Residentes de Cardiología (CONAREC). Se realizó la recolección de datos durante los meses de marzo a agosto del año 2020. Se relevó el tratamiento hipolipemiante que recibían, los motivos detrás de la no utilización de estatinas en dosis adecuadas, y los valores de perfil lipídico en caso de contar con un registro en los últimos 6 meses previos a la inclusión. Resultados: Se incluyeron 1000 pacientes consecutivos de 24 centros, correspondientes a 11 provincias. Un 85,9% se encontraba bajo tratamiento con estatinas; un 4,8%, con ezetimibe; un 2,4% con fibratos; y un 13%, sin tratamiento. De aquellos pacientes en tratamiento con estatinas, un 67% recibía estatinas en altas dosis (58% del total de pacientes). Un total de 509 pacientes presentaban medición del C-LDL dentro de los últimos 6 meses. El valor promedio de C-LDL fue de 94 (90,6-97,8) mg/dL; el de C-LDL, 41 (40,7-42,6) mg/dL; y el de triglicéridos, 151 (142,9-159,8) mg/dL. Un 30% se encontraba con valores por debajo del corte de 70 mg/dL. Un 16% se encontraba con valores por debajo de 55 mg/dL. Un 37% de los pacientes presentaba C-LDL >100 mg/dL. Conclusiones: En este estudio multicéntrico de pacientes en prevención secundaria desarrollado en la República Argentina, poco más de la mitad presentaba tratamiento con estatinas en altas dosis, con una escasa utilización de ezetimibe. El subtratamiento se reflejó en los valores de C-LDL, con más de dos tercios de los pacientes fuera de rango terapéutico y, por lo tanto, lejos de las recomendaciones de las guías clínicas.

ABSTRACT Background: The correct management of lipid-lowering treatment is one of the key factors for the reduction of cardiovascular risk in secondary prevention patients. High-dose statins, ezetimibe, and more recently PCSK9 inhibitors (PCSK9i) are the main tools available to meet LDL cholesterol (LDL-C) therapeutic goals in these patients. Despite the overwhelming evidence in their favor, these therapies are greatly underutilized worldwide, with low levels of adherence and therapeutic inertia. In Argentina, there is scarce evidence on the quality of lipid-lowering treatment and the rate of patients in secondary prevention with a controlled lipid profile according to national and international guidelines. Methods: A prospective, multicenter, cross-sectional study including consecutive patients in secondary prevention for cardiovascular events from hospitals of Argentina with a Medical Residency system affiliated to CONAREC, was carried out from March to August 2020. Data was collected on the lipid-lowering treatment received, the reasons behind the non-use of statins in adequate doses and the lipid profile levels in case of having a record from the last 6 months prior to inclusion. Results: Among 1000 consecutive patients included from 24 centers corresponding to 11 provinces, 85.9% was treated with statins, 4.8% with ezetimibe, 2.4% with fibrates, and 13% was without treatment. In the case of patients treated with statin therapy, 67% was receiving high-dose statins (58% of the total number of patients). A total of 509 patients presented LDL-C assessment within the last 6 months. Mean LDL-C was 94 (90.6-97.8) mg/dl, HDL cholesterol 41 (40.7-42.6) mg/dl, and triglycerides 151 (142.9-159.8) mg/dl. In 30% of cases, LDL-C was below the cut-off value of 70 mg/dl and in 16% below 55 mg/ dl. In 37% of patients, LDL-C was >100 mg/dl. Conclusions: In this multicenter secondary prevention study performed in Argentina, just over half of the patients presented high-dose statin treatment, with scarce use of ezetimibe. Undertreatment was reflected in LDL-C values, with more than two-thirds of patients outside the therapeutic range, and therefore far from clinical guideline recommendations.

Manejo de la hipercolesterolemia desde dos ángulos diferentes / Hypercholesterolemia management from two different points of view

RESUMEN La cardiopatía isquémica y los accidentes cerebrovasculares son la primera causa de muerte en el mundo. La enfermedad cardiovascular de origen ateroesclerótico es un problema internacional de salud, que constituye una carga social, sanitaria y económica. Se realizó un análisis de las principales guías internacionales sobre dislipoproteinemias y su manejo, como las de la Sociedad Europea de Cardiología y las del Colegio Americano de Cardiología/Asociación Americana del Corazón. También, de los principales artículos publicados en los últimos cinco años sobre el manejo de la hipercolesterolemia, de los cuales se tomaron 20 publicaciones en Medline, Google Académico y SciELO. Las mencionadas guías reúnen las recomendaciones de sus respectivas organizaciones y las combinan con nuevas. Ambas mantienen el uso de scores de riesgo y discrepan sobre la imagenología en la determinación del tratamiento, al igual que en el uso de drogas no estatinas. Se plantea que la mejor intervención para prevenir la enfermedad cardiovascular es la promoción de un estilo de vida saludable (AU).

ABSTRACT Ischemic cardiomyopathy and cerebrovascular stroke are the first causes of death in the world. Cardiovascular disease of atherosclerotic origins is an international health problem that is also a social, sanitary and economic burden. The authors analyzed the main international guidelines on dyslipoproteinemia, like the ones from the European Society of Cardiology and the American College of Cardiology/American Heart Association. They also considered the main articles published in the last five years on the management of hypercholesterolemia and chose 20 of them available in Medline, Google Scholar and SciELO. The before-mentioned guidelines gather the recommendations of their own organizations, and combine them with new ones. They both keep using risk scores on and differ on medical imaging determining the treatment, and also in the use of non-statin drugs. It is stated that the better intervention to prevent cardiovascular disease is the promotion of a healthy lifestyle (AU).

Associação entre Terapia com Estatinas e Menor Incidência de Hiperglicemia em Pacientes Internados com Síndromes Coronarianas Agudas / Association between Statin Therapy and Lower Incidence of Hyperglycemia in Patients Hospitalized with Acute Coronary Syndromes

Resumo Fundamento O maior risco de se desenvolver diabetes com o uso de estatinas é um desafio para a segurança do uso dessa classe de medicamentos em longo prazo. No entanto, poucos estudos analisaram essa questão durante síndromes coronarianas agudas (SCA). Objetivos Investigar a associação entre início precoce da terapia com estatina e níveis de glicemia em pacientes admitidos com SCA. Métodos Este foi um estudo retrospectivo de pacientes hospitalizados por SCA. Pacientes que nunca haviam usado estatinas foram incluídos e divididos segundo uso ou não de estatina nas primeiras 24 horas de internação. O desfecho primário foi a incidência de hiperglicemia na internação (definida como pico de glicemia > 200mg/dL). Modelos de regressão logística e modelos lineares multivariados foram usados para ajuste quanto a fatores de confusão e um modelo de pareamento por escore de propensão foi desenvolvido para comparações entre os dois grupos de interesses. Um valor de p menor que 0,05 foi considerado estatisticamente significativo. Resultados Um total de 2357 pacientes foram incluídos, 1704 deles alocados no grupo que receberam estatinas e 653 no grupo que não receberam estatinas nas primeiras 24 horas de internação. Após os ajustes, uso de estatina nas primeiras 24 horas foi associado com uma menor incidência de hiperglicemia durante a internação (OR ajustado = 0,61, IC95% 0,46-0,80; p < 0,001) e menor necessidade de uso de insulina (OR ajustado = 0,56, IC 95% 0,41-0,76; p < 0,001). Essas associações mantiveram-se similares nos modelos de pareamento por escore de propensão, bem como após análises de sensibilidade, como exclusão de pacientes que desenvolveram choque cardiogênico, infecção grave ou pacientes que foram a óbito durante a internação hospitalar. Conclusões Entre os pacientes internados com SCA que não receberam estatinas previamente, a terapia precoce com estatina associou-se independentemente com menor incidência de hiperglicemia durante a internação.

Abstract Background Increased risk of new-onset diabetes with statins challenges the long-term safety of this drug class. However, few reports have analyzed this issue during acute coronary syndromes (ACS). Objective To explore the association between early initiation of statin therapy and blood glucose levels in patients admitted with ACS. Methods This was a retrospective analysis of patients hospitalized with ACS. Statin-naïve patients were included and divided according to their use or not of statins within the first 24 hours of hospitalization. The primary endpoint was incidence of in-hospital hyperglycemia (defined as peak blood glucose > 200 mg/dL). Multivariable linear and logistic regression models were used to adjust for confounders, and a propensity-score matching model was developed to further compare both groups of interest. A p-value of less than 0.05 was considered statistically significant. Results A total of 2,357 patients were included, 1,704 of them allocated in the statin group and 653 in the non-statin group. After adjustments, statin use in the first 24 hours was associated with a lower incidence of in-hospital hyperglycemia (adjusted OR=0.61, 95% CI 0.46-0.80; p < 0.001) and lower need for insulin therapy (adjusted OR = 0.56, 95% CI 0.41-0.76; p < 0.001). These associations remained similar in the propensity-score matching models, as well as after several sensitivity analyses, such as after excluding patients who developed cardiogenic shock, severe infection or who died during index-hospitalization. Conclusions Among statin-naïve patients admitted with ACS, early statin therapy was independently associated with lower incidence of in-hospital hyperglycemia.

Abstract Introduction: Among the main causes of death in Colombia, Latin America, and the general population are pathologies of cardiovascular origin, which have an important relationship with dyslipidemias. Objective: The objective of the study was to establish the prevalence of the use of lipid-lowering drugs in a Colombian population during 2016. Material and methods: A cross-sectional study was conducted using a population database of the Colombian Health System between January and June 2016. Site: outpatients of Colombia. Participants. Researchers considered all patients who had received this class of drug to establish the prevalence of the use of lipid-lowering drugs. Main measurements. Prevalence of use of lipid-lowering drugs. Results: From a population of 4,328,688 patients, a total of 282,002 were prescribed a lipid-lowering drug; the mean age was 64.2 ± 13.3 years and women comprised 50.4% of the users. The estimated prevalence of lipid-lowering drug use was 6.5%. Statins (86.3%) were the most commonly used lipid-lowering drugs (atorvastatin: 81.0%, lovastatina: 14.4%) followed by fibrates (13.1%) and ezetimibe (0.6%). Conclusions: A low proportion of people are being treated with lipid-lowering drugs, according to the estimated prevalence of dyslipidemia.

Logro de las metas de colesterol LDL en pacientes con enfermedad coronaria aterosclerótica establecida / Achievement of LDL cholesterol targets in patients with coronary artery disease

Resumen Introducción: Los pacientes con enfermedad aterosclerótica establecida requieren tratamiento con estatinas para reducir la probabilidad de nuevos eventos. Objetivo: Identificar el porcentaje de pacientes con enfermedad coronaria aterosclerótica establecida que logran niveles de cLDL (colesterol LDL) inferiores a 70mg/dl y describir su distribución en tres grupos terapéuticos: estatinas, otros hipolipemiantes y sin tratamiento. Métodos: Estudio observacional descriptivo de corte transversal, en el que se seleccionaron pacientes de tres hospitales de alta complejidad, mayores de 18 años, con enfermedad aterosclerótica diagnosticada a partir del año 2017. El registro del perfil lipídico corresponde al realizado al menos tres meses después del diagnóstico. Resultados: Se incluyeron en total 746 pacientes con enfermedad coronaria aterosclerótica, con un promedio de edad de 65,3±10,9 años y predominio del sexo masculino (75,5%). Del total de los pacientes evaluados se prescribieron un 97,8% de terapia con al menos una estatina, 0,7% de otros hipolipemiantes y 1,5% no presentaron tratamiento. Los pacientes con niveles de cLDL inferior a 70mg/dl corresponden al 56%. Conclusiones: La extensa divulgación de guías de práctica clínica para dislipidemias en adultos en Colombia, y la incorporación de estatinas de alta intensidad, demuestran una mejoría en la proporción del cumplimiento en metas de cLDL para pacientes con enfermedad aterosclerótica establecida. Sin embargo, una alta proporción aún persiste fuera de metas, lo cual constituye una oportunidad de optimización del uso de terapias disponibles y recientemente desarrolladas.

Abstract Introduction: Patients with established atherosclerotic disease require treatment with statins in order to reduce the probability of new events. Objective: To identify the percentage of patients with established atherosclerotic coronary disease that achieve cLDL (LDL - cholesterol) levels less than 70mg/dL, and to describe its distribution in three treatment groups: statins, other lipid lowering drugs, and without treatment. Methods: A cross-sectional, descriptive observational study was conducted on patients diagnosed with atherosclerotic disease from 2017 and over 18-years-old from 3 tertiary hospitals. A record was made of the lipid profile that was performed at least three months after the diagnosis. Results: A total of 746 patients with atherosclerotic coronary disease were included. The mean age was 65.3±10.9 years and the majority (75.5%) were males. Of the total number of patients evaluated, 97.8% were prescribed a therapy with at least one statin, 0.7% with other lipid-lowering drugs, and 1.5% had no treatment. Just over half (56%) of the patients had cLDL levels of less than 70mg/dL. Conclusions: The widespread use of clinical practice guidelines for dyslipidaemias in adults in Colombia, and the incorporation of high-intensity statins, has led to an improvement in the proportion of patients with established atherosclerotic disease achieving cLDL targets. However, a high percentage still does not reach the targets, which suggests a need for an improving of the use of available and recently developed therapies.

Effects of statin therapy on outcomes of ischemic stroke: a real-world experience in Brazil / Efeitos da terapia com estatinas nos desfechos do acidente vascular cerebral isquêmico: uma experiência de mundo real no Brasil

ABSTRACT Background: Statin therapy has become one of the most important advances in stroke secondary prevention. Objective: To provide evidence from real-world data for evaluating detailed associations between secondary prevention of stroke and statin use in Brazil. Methods: We conducted a prospective cohort study including consecutive patients diagnosed with an ischemic stroke. Subjects were classified into non-statin, simvastatin 20 mg, simvastatin 40 mg, and high-potency statin groups. We also registered the onset of statin therapy, previous use of statins, the adherence to medication, and if there was discontinuation of the therapy. After two years, the functional outcome, stroke recurrence, major cardiovascular events, and mortality were assessed. Results: Among the 513 patients included in our cohort, there were 96 (18.7%) patients without statins, 169 (32.9%) with simvastatin 20 mg, 202 (39.3%) with simvastatin 40 mg, and 46 (9.0%) with high-potency statins. Patients without statins were at increased risk of stroke recurrence and worse functional outcomes. Concerning etiology, evidence of beneficial use of statins was observed in cases of large-artery atherosclerosis, small-vessel occlusion, and stroke of undetermined cause. Those who presented poor adherence to statins or discontinuation of the treatment had worse prognosis after stroke whereas the early onset of statins use was associated with better outcomes. Patients with simvastatin 40 mg and high-potency statins presented the best functional recovery throughout the follow-up. Conclusions: Statins play an important role in the treatment of ischemic stroke, preventing stroke recurrence and cardiovascular events, and improving functional performance.

RESUMO Introdução: A terapia com estatinas tornou-se um dos avanços mais importantes na prevenção secundária do acidente vascular cerebral (AVC). Objetivo: Fornecer evidências de dados do mundo real para avaliar associações detalhadas entre a prevenção secundária do AVC e o uso de estatinas no Brasil. Métodos: Realizamos um estudo de coorte prospectivo, incluindo pacientes consecutivos com diagnóstico de AVC isquêmico. Os indivíduos foram classificados em grupos sem estatinas, sinvastatina 20 mg, sinvastatina 40 mg e estatina de alta potência. Também registramos o início da terapêutica com estatinas, o uso prévio de estatinas, a adesão à medicação e se houve descontinuação da terapia. Após dois anos, foram avaliados o resultado funcional, a recorrência do AVC, os principais eventos cardiovasculares e a mortalidade. Resultados: Entre os 513 pacientes incluídos em nossa coorte, havia 96 (18,7%) pacientes sem estatinas, 169 (32,9%) com sinvastatina 20 mg, 202 (39,3%) com sinvastatina 40 mg e 46 (9,0%) com estatinas de alta potência. Pacientes sem estatinas apresentaram maior risco de recorrência de AVC e piores resultados funcionais. Em relação à etiologia, foram observadas evidências do benefício das estatinas nos casos de aterosclerose de grandes artérias, oclusão de pequenos vasos e AVC de causa indeterminada. Aqueles com baixa adesão às estatinas ou que interromperam o uso tiveram pior prognóstico após o AVC, enquanto o início precoce do uso de estatinas foi associado a melhores resultados. Pacientes com sinvastatina 40 mg e estatinas de alta potência apresentaram melhor recuperação funcional ao longo do período de acompanhamento. Conclusões: As estatinas desempenham um importante papel no tratamento do AVC isquêmico, prevenindo sua recorrência e eventos cardiovasculares e melhorando o desempenho funcional.

ABSTRACT Introduction: Any form of diabetic retinopathy can be accompanied by the presence of diabetic macular edema. The use of statins in patients with diabetes mellitus and diabetic macular edema has been suggested as a therapeutic measure. Objectives: To describe, in a general way, the treatment of diabetic macular edema and, particularly, some outcomes obtained with the use of statins. Methods: A relevant literature search on the subject was carried out in the first half of 2019. Review and research articles published in the last ten years were assessed, taken from different databases, such as PubMed, Cochrane, SciELO, as well as from web pages, written in Spanish, Portuguese or English. Pubmed, Google and Google Scholar were used as engines for searching scientific information. The following keywords were used: diabetes mellitus, tratamiento [treatment], estatinas [statins], and edema macular diabetic [diabetic macular edema]. Articles that did not meet the objectives of the present work were excluded, which allowed the study of 87 articles, of which 57 were referenced. Conclusions: Strict glycemic control and confronting modifiable risk factors in patients with diabetes mellitus represents the most important measure to avoid and reduce the appearance and progression of diabetic macular edema. When established, appropriate or specific treatment should be used. The use of statins could be an important complement for the prevention and treatment of diabetic macular edema(AU)

Use of statins and the risk of developing pre-diabetes and diabetes: a longitudinal study in individuals aged 40 years or older / Uso de estatina e risco de desenvolver pré-diabetes e diabetes: um estudo longitudinal em pessoas com 40 anos ou mais / Uso de estatinas y el riesgo de desarrollar prediabetes y diabetes: un estudio longitudinal en personas de 40 años o mayores

SUMMARY Background: Statins are the main therapeutic option for the control of dyslipidemias and cardiovascular prevention. However, studies indicate the possibility of the use of statins cause increases in blood glucose levels. Aim: The aim of the study was to analyze the use of statin and the risk of developing pre-diabetes (DM) or DM. Methods: This was a cohort study conducted with individuals aged 40 years or older, living in a medium-sized municipality in the north of Paraná, Brazil. Data were obtained through individual interviews and laboratory tests in the years 2011 (baseline) and 2015 (follow-up). Dependent variables were the development of DM (yes; no) and the development of pre-DM or DM (yes; no). The independent variable was the use of statins (no use; use only in 2011; use only in 2015; use in 2011 and 2015). Poisson (loglinear) regression analysis was used to calculate the relative risk (RR) and 95% confidence intervals (95% CI) in generalized linear models. Results: An association was observed between the use of statins and the incidence of DM (RR 2.89, 95% CI: 1.59-5.24) and the incidence of pre-DM or DM (RR 2.01, 95% CI: 1.39-2.92) for the group of individuals who used statins only in 2015. Conclusions: The present study identified an association between the use of statins and the incidence of pre-DM and DM only for those who used them exclusively in 2015.

RESUMO Introdução: As estatinas são a principal opção terapêutica para o controle de dislipidemias e prevenção cardiovascular. No entanto, estudos indicam a possibilidade do uso de estatinas causar aumentos nos níveis de glicose no sangue. Objetivo: O objetivo do estudo foi analisar o uso de estatina e o risco de desenvolver pré-diabetes (DM) ou DM. Métodos: Estudo de coorte realizado com indivíduos com 40 anos ou mais de idade, residentes em um município de médio porte no norte do Paraná. Os dados foram obtidos por meio de entrevistas individuais e exames laboratoriais nos anos de 2011 (linha de base) e 2015 (acompanhamento). As variáveis dependentes foram o desenvolvimento de DM (sim; não) e o desenvolvimento de pré-DM ou DM (sim; não). A variável independente foi o uso de estatinas (sem uso; uso apenas em 2011; uso apenas em 2015; uso em 2011 e 2015). A análise de regressão de Poisson (log-linear) foi utilizada para calcular o risco relativo (RR) e os intervalos de confiança de 95% (IC95%) em modelos lineares generalizados. Resultados: Observou-se associação entre o uso de estatinas e a incidência de DM (RR 2,89, IC 95%: 1,59-5,24) e a incidência de pré-DM ou DM (RR 2,01, IC 95%: 1,39-2,92) para o grupo de indivíduos que usaram estatinas apenas em 2015. Conclusões: O presente estudo identificou associação entre o uso de estatinas e a incidência de pré-DM e DM apenas para aqueles que as usaram exclusivamente em 2015.
