ABSTRACT
Resumo Fundamento: As diretrizes da Sociedade Europeia de Cardiologia recomendam um nível de colesterol LDL (LDL-C) < 55 mg/dL para pacientes com doença cardiovascular estabelecida. Embora a fórmula de Friedewald ainda seja amplamente utilizada para estimar o LDL-C, a fórmula mais recente de Martin-Hopkins mostrou maior precisão. Objetivos: Nosso objetivo foi avaliar: A) a proporção de pacientes que atingiram a meta de LDL-C e as terapias utilizadas em um centro terciário; B) o impacto da utilização do método de Martin-Hopkins em vez do método de Friedewald na proporção de pacientes controlados. Métodos: Estudo transversal monocêntrico, incluindo pacientes consecutivos pós-infarto do miocárdio, acompanhados por 20 cardiologistas, em um hospital terciário. Os dados foram coletados retrospectivamente de consultas clínicas realizadas após abril de 2022. Para cada paciente, os níveis de LDL-C e o atingimento das metas foram estimados a partir de um perfil lipídico ambulatorial, utilizando as fórmulas de Friedewald e Martin-Hopkins. Um valor-p bicaudal < 0,05 foi considerado estatisticamente significativo para todos os testes. Resultados: Foram incluídos 400 pacientes (com 67 ± 13 anos, 77% do sexo masculino). Utilizando a fórmula de Friedewald, a mediana de LDL-C sob terapia foi de 64 (50-81) mg/dL, e 31% tinham LDL-C dentro da meta. Estatinas de alta intensidade foram usadas em 64% dos pacientes, 37% estavam em uso de ezetimiba e 0,5% estavam em uso de inibidores de PCSK9. A terapia combinada de estatina de alta intensidade + ezetimiba foi utilizada em 102 pacientes (26%). A aplicação do método de Martin-Hopkins reclassificaria um total de 31 pacientes (7,8%). Entre aqueles considerados controlados pela fórmula de Friedewald, 27 (21,6%) teriam LDL-C estimado por Martin-Hopkins acima da meta. Conclusões: Menos de um terço dos pacientes pós-infarto do miocárdio apresentaram LDL-C dentro da meta. A aplicação da fórmula de Martin-Hopkins reclassificaria um quinto dos pacientes presumivelmente controlados no grupo de pacientes não controlados.
Abstract Background: The European Society of Cardiology guidelines recommend an LDL-cholesterol (LDL-C) < 55 mg/dL for patients with established cardiovascular disease. While the Friedewald equation to estimate LDL-C is still widely used, the newer Martin-Hopkins equation has shown greater accuracy. Objectives: We aimed to assess: A) the proportion of patients reaching LDL-C goal and the therapies used in a tertiary center; B) the impact of using the Martin-Hopkins method instead of Friedewald's on the proportion of controlled patients. Methods: A single-center cross-sectional study including consecutive post-myocardial infarction patients followed by 20 cardiologists in a tertiary hospital. Data was collected retrospectively from clinical appointments that took place after April 2022. For each patient, the LDL-C levels and attainment of goals were estimated from an ambulatory lipid profile using both Friedewald and Martin-Hopkins equations. A two-tailed p-value of < 0.05 was considered statistically significant for all tests. Results: Overall, 400 patients were included (aged 67 ± 13 years, 77% male). Using Friedewald's equation, the median LDL-C under therapy was 64 (50-81) mg/dL, and 31% had LDL-C within goals. High-intensity statins were used in 64% of patients, 37% were on ezetimibe, and 0.5% were under PCSK9 inhibitors. Combination therapy of high-intensity statin + ezetimibe was used in 102 patients (26%). Applying the Martin-Hopkins method would reclassify a total of 31 patients (7.8%). Among those deemed controlled by Friedewald's equation, 27 (21.6%) would have a Martin-Hopkins' LDL-C above goals. Conclusions: Less than one-third of post-myocardial infarction patients had LDL-C within the goal. Applying the Martin-Hopkins equation would reclassify one-fifth of presumably controlled patients into the non-controlled group.
ABSTRACT
Introducción. Un biomarcador se define como una alteración molecular presente en el desarrollo de la patogénesis del cáncer, que puede ser utilizada para el diagnóstico temprano de la enfermedad. La medición del biomarcador se hace por medio de diversas técnicas, como bioquímica, inmunohistoquímica o biología molecular, en diferentes tipos de muestras, como tejido, sangre periférica y orina. El biomarcador ideal será aquel que sea válido y específico a la vez, que sea no invasivo, barato y fácilmente detectable. El uso de biomarcadores para la detección temprana del cáncer debe seguir un desarrollo ordenado y sistemático antes de introducirlos en la práctica clínica. Métodos. Se realizó una búsqueda exhaustiva en las bases de datos de PubMed y Embase, seleccionando los artículos pertinentes para revisarlos acorde a la temática específica de interés. Resultados. Se propone la sistematización del desarrollo de biomarcadores en cinco grandes fases, las cuales tienen la característica de ser ordenadas desde las evidencias más tempranas hasta las fases finales de su estudio. Conclusiones. El correcto desarrollo de biomarcadores hace posible la introducción de intervenciones terapéuticas en el ámbito de la prevención secundaria del cáncer.
Introduction. A biomarker can be defined as a molecular alteration present in the development of cancer pathogenesis which can be used for early diagnosis of the disease. The measurement of the biomarker can be carried out through various techniques such as biochemistry, immunohistochemistry, molecular biology, in different types of samples such as tissue, peripheral blood, and urine. The ideal biomarker will be one that is valid and specific while is non-invasive, cheap, and easily detectable. The use of biomarkers for the early detection of cancer must follow an orderly and systematic development before introducing them into clinical practice. Methods. An exhaustive search was performed in PubMed and Embase databases, selecting the relevant articles according to the specific topic of interest. Results. Systematization of the development of biomarkers in five large phases is proposed, which has the characteristic of being ordered from the earliest evidence to the final phases of their study. Conclusions. The correct development of biomarkers makes possible the introduction of therapeutic interventions in the field of secondary prevention of cancer.

Na atualidade, as intervenções coronárias percutâneas com implante de um stent farmacológico constituem o principal método de revascularização miocárdica em centros hospitalares terciários, independentemente da forma clínica de apresentação da doença arterial coronária. É de conhecimento geral que, para sua efetivação, há necessidade do uso de um esquema antiplaquetário duplo, constituído pela associação do ácido acetilsalicílico e um inibidor dos receptores plaquetários P2Y12, que é o cerne da prevenção das tromboses após implantes das endopróteses, sendo também indicado para prevenir a ocorrência de eventos aterotrombóticos na evolução clínica tardia, qualquer que seja o modelo de stent utilizado. Após período variável de tempo, independentemente de fatores como forma clínica de apresentação da coronariopatia e do tipo de stent implantado, esse esquema é interrompido, e, na atualidade, as principais diretrizes preconizam a suspensão do inibidor dos receptores P2Y12 e a manutenção do ácido acetilsalicílico em longo prazo como uma das principais medidas farmacológicas de prevenção secundária da aterosclerose. No entanto, recentemente, em razão de sua maior potência antiplaquetária e provável menor potencial de causar hemorragias significantes, em especial no tubo digestivo, os inibidores P2Y12 têm sido considerados alternativa válida e atraente como antiplaquetário de utilização em longo prazo, alternativa ainda não referendada pelas diretrizes. Esta revisão discute os pormenores relacionados a essa importante decisão que deve ser tomada pelo cardiologista no momento da interrupção dos diferentes esquemas antitrombóticos inicialmente utilizados após uma intervenção coronária percutânea. Em princípio, a escassez de estudos clínicos conclusivos e normativos, em especial na população tratada por meio de uma intervenção percutânea, faz com que o ácido acetilsalicílico ainda se mantenha como o único antiagregante plaquetário com indicação classe I com a finalidade de prevenção secundária da aterosclerose.
Currently, percutaneous coronary intervention with a drug-eluting stent implantation is the main method of myocardial revascularization in tertiary care hospitals, regardless of the clinical presentation of coronary artery disease. It is well known that to be effective, it requires the use of a dual antiplatelet therapy, which is a combination of acetylsalicylic acid and a P2Y12 platelet receptor inhibitor, which plays a key role in preventing thromboses after endoprosthesis implantation and is also indicated to prevent atherothrombotic events in the late clinical course, regardless of the stent model used. After a variable period of time, depending on some factors, such as the clinical presentation of coronary artery disease and the type of stent implanted, this therapy is discontinued, and the main current guidelines recommend interrupting the P2Y12 receptor inhibitor and maintaining acetylsalicylic acid in the long term, as one of the main pharmacological measures for secondary prevention of atherosclerosis. However, recently, due to their greater antiplatelet potency and probable lower potential for significant bleeding, especially in the digestive tract, P2Y12 inhibitors have been considered a valid and attractive option as an antiplatelet agent for long-term use; but this alternative has not been endorsed by guidelines yet. This review discusses the details related to this important decision that must be made by cardiologists when discontinuing the different antithrombotic therapies initially used after percutaneous coronary intervention. In principle, the scarcity of conclusive and normative clinical studies, especially in the population treated by percutaneous intervention, means that acetylsalicylic acid is the only antiplatelet agent with class I indication for secondary prevention of atherosclerosis.
ABSTRACT
The cardioprotective effect of postmenopausal hormone replacement therapy (HRT) has been demonstrated in several studies. Similarly, physical exercise has yielded positive results. However, the effects of their combination remain inconclusive. This review describes the combined effects of physical exercise and hormone therapy on cardiovascular and metabolic health in postmenopausal women. We searched the Scopus, Web of Science, PubMed, and Embase databases and included randomized controlled trials published up to December 2021 on the combined effects of physical exercise and hormone therapy on cardiovascular and metabolic health in postmenopausal women. We identified 148 articles, of which only seven met the inclusion criteria (386 participants; 91 [23%] HRT + exercise; 104 [27%] HRT; 103 [27%] exercise; 88 [23%] placebo). The combined treatment further decreased systolic blood pressure (SBP) compared to the isolated effect of aerobic training (AT) (mean difference [MD]=-1.69; 95% confidence interval [CI]=-2.65 to -0.72, n=73). Nevertheless, it attenuated the decrease in diastolic blood pressure (DBP) (MD=0.78; 95%CI: 0.22-1.35, n=73), and the increase in peak oxygen consumption (VO2 peak) promoted by exercise (AT + HRT=2.8±1.4 vs AT + placebo=5.8±3.4, P=0.02). The combination of AT and oral HRT improved SBP. However, AT alone seemed to have a better effect on physical fitness and DBP in postmenopausal women.
ABSTRACT
ABSTRACT Objective: to develop and analyze content and face validity evidence of a board game to promote healthy lifestyle habits for patients with coronary artery disease. Method: this is a psychometric study of development and validity of a board game for health education. Data collection was carried out between October 2021 and January 2022. Initially, the game rules were described and, sequentially, themes related to cardiovascular prevention were identified, used as a basis for card development. The game was submitted to assessment by 14 experts in terms of clarity, theoretical relevance, practical relevance, image visibility and relationship between image and text, through a Likert scale score. The content validity coefficient was calculated for each round, with a coefficient greater than 0.57 being considered valid. New assessment rounds were performed until the appropriate coefficient was reached. Results: the board game was built containing images of anthropomorphized hearts alluding to healthy lifestyle habits and 45 spaces. A total of 69 cards were developed containing the themes of healthy eating, physical activity and the importance of smoking and alcohol cessation. In the first round of assessment, three cards did not reach the minimum content validity coefficient. They were reformulated and sent to a second round of assessment, and was considered validated in this new round. Conclusion: the game, its rules and its content showed adequate content validity evidence after the second round. Further studies to analyze its effect on lifestyle modification should be carried out.

ABSTRACT
ABSTRACT Objective: To evaluate whether patients older than 60 years admitted for fracture treatment had a history of previous fracture, a diagnosis of osteoporosis, or were under treatment for bone fragility. Methods: Retrospective study including 100 patients older than 60 years with fracture. Fracture location, bone densitometry within the past two years, previous diagnosis and osteoporosis treatment, and previous fracture within the past five years were assessed. Using Fisher's test, it was evaluated whether there was an association between previous fracture and osteoporosis treatment. Results: The most prevalent fracture was in the proximal femur (48%). Of the patients, 18% had fracture in the last five years, with 22% of them diagnosed with osteoporosis, and 22% under treatment. Previous fracture in the last five years was not associated with having a diagnosis of osteoporosis, having had bone densitometry, or being under treatment for osteoporosis. Conclusion: Among patients with previous fracture, only 22% were aware of their diagnosis of osteoporosis, and less than 25% of them were under bone fragility treatment. Previous fracture in the past five years had no association with having a diagnosis of osteoporosis, having had bone densitometry, or being on osteoporosis treatment. Level of Evidence III, Retrospective Study.
RESUMO Objetivo: Avaliar se os pacientes com mais de 60 anos internados para tratamento de fraturas têm história de fratura prévia, diagnóstico de osteoporose ou se estão em tratamento para fragilidade óssea. Métodos: Estudo retrospectivo que inclui 100 pacientes maiores de 60 anos com fratura. Avaliamos a localização da fratura, a densitometria óssea nos últimos dois anos, o diagnóstico e os tratamentos anteriores de osteoporose, assim como a presença de fratura prévia nos últimos cinco anos. Através de testes de Fisher avaliamos se houve associação entre fratura prévia e tratamento de osteoporose. Resultados: A fratura mais prevalente foi na extremidade proximal do fêmur (48%). Do total de pacientes, 18% tiveram fratura nos últimos cinco anos, sendo que 22% deles tinham diagnóstico de osteoporose e 22% estavam em tratamento. Fratura prévia nos últimos cinco anos não teve associação com diagnóstico de osteoporose, realização de densitometria óssea ou tratamento para osteoporose. Conclusão: Entre os pacientes com fratura prévia, apenas 22% estavam cientes do diagnóstico de osteoporose, e menos de 25% deles estavam em tratamento para fragilidade óssea. Não houve associação de fratura prévia nos últimos cinco anos com diagnóstico de osteoporose, realização de densitometria óssea ou tratamento para osteoporose.

ABSTRACT
Resumo Fundamento A prevenção secundária é recomendada a pacientes com evidência de doença arterial coronariana (DAC) independentemente da indicação de tratamento por cirurgia de bypass da artéria coronária (CABG) ou intervenção coronária percutânea (ICP). Objetivos Este estudo avaliou se o tratamento clínico, a ICP ou o CABG teve influência na adesão à prevenção secundária farmacológica em pacientes com DAC estável. Métodos Esta coorte incluiu pacientes com idade ≥40 anos com DAC estável confirmada por angiografia coronária estável. A decisão por tratamento clínico isolado, ou combinado com ICP ou CABG foi feita por médicos assistentes. A adesão às drogas prescritas recomendadas pelas diretrizes de prevenção secundária (tratamento farmacológico ótimo), incluindo agentes antiplaquetários, drogas hipolipemianetes, betabloqueadores, e bloqueadores do sistema angiotensina aldosterona, foi avaliada no acompanhamento. Diferenças com valores de p < 0,05 foram consideradas estatisticamente significativas. Resultados Dos 928 pacientes incluídos inicialmente, 415 apresentaram DAC leve e 66 apresentaram DAC leve a moderada. O período médio de seguimento foi 5,2 ± 1,5 anos. Os pacientes submetidos ao CABG apresentaram maior probabilidade de receberem tratamento farmacológico ótimo que aqueles submetidos à ICP ou tratamento clínico (63,5% versus 39,1% versus 45,7% respectivamente, p=0,003). Fatores basais independentemente associados com maior probabilidade de prescrição de tratamento ótimo foram CABG [39% maior (6% - 83%, p=0,017)] em comparação a outros tratamentos e diabetes [25% maior (1% - 56%), p=0,042] em comparação à ausência de diabetes. Conclusões Pacientes com DAC submetidos ao CABG são mais frequentemente tratados com prevenção secundária farmacológica ótima que pacientes tratados com ICP ou exclusivamente com tratamento clínico.
Abstract Background Secondary prevention is recommended for patients with evidence of coronary artery disease (CAD) regardless of the indication for treatment by coronary artery bypass graft surgery (CABG) or percutaneous coronary intervention (PCI). Objectives This study evaluated whether clinical treatment, PCI or CABG had an influence on adherence to the pharmacological secondary prevention in patients with stable CAD. Methods This cohort included patients aged ≥40 years with stable CAD confirmed by coronary angiography. The decision for medical treatment alone, or additionally with PCI or CABG, was made by the attending physicians. Adherence to the prescribed drugs recommended by the guidelines for secondary prevention (optimal pharmacological treatment), including antiplatelet agents, lipid-lowering drugs, beta-blockers, and renin-angiotensin-aldosterone system blockers, was assessed at follow-up. Differences were considered significant for p values <0.05. Results From 928 patients enrolled at baseline, 415 had mild CAD and 66 moderate to severe CAD. The average follow-up was 5.2 ± 1.5 years. Patients submitted to CABG were more likely to receive the optimal pharmacological treatment than those submitted to PCI or treated clinically (63.5% versus 39.1% versus 45.7% respectively, p=0.003). Baseline factors independently associated with greater probability of having a prescription of optimal treatment at follow-up were CABG [39% higher (6% - 83%, p=0.017) and diabetes [25% higher (1% - 56%), p=0.042] than their counterparts treated by other methods and participants without diabetes, respectively. Conclusions Patients with CAD submitted to CABG are more commonly treated with optimal pharmacological secondary prevention than patients treated by PCI or exclusively with medical therapy.
ABSTRACT
Abstract Objective: This study monitors trends in access to cancer screening, focusing on mammography, Papanicolaou (Pap smear), and Prostate-Specific Antigen (PSA), assessing the magnitude of inequality in the city of São Paulo from 2003 to 2015 according to education level. Method: This is a cross-sectional population-based study conducted with data from the 2003, 2008, and 2015 editions of the Health Survey of the City of São Paulo (ISA-Capital). Outcome variables were the proportion of mammography, Papanicolaou (Pap smear), and Prostate-Specific Antigen (PSA) tests according to the protocols. Inequality was measured by education level according to years of study. For static analysis, Poisson regression was used to estimate proportion ratios. Results: The proportion of Pap smears remained stationary at a high level (>89%) throughout the study period, while access to mammography and PSA tests significantly increased in the 2003-2015 period. The present results indicate inequalities in access to cancer screening due to education, and being more expressive for mammography and PSA tests. However, this inequality significantly decreased over the period analyzed comparing the most educated individuals with those with the lowest educational level. In addition, an increase in the proportion of tests performed in the Brazilian Unified Health System was identified, especially for mammography and PSA tests, in the period 2003-2015. Conclusions: The inequalities observed in the access to preventive exams were influenced by the level of education. The offer of exams was expanded, more significantly for mammography and PSA, especially among the less educated group.

ABSTRACT
Acute transient or permanent retinal arterial ischemia is ocular and systemic emergency requiring immediate diagnosis and treatment. Transient monocular vision loss is transient retinal arterial ischemia which leaves no permanent deficits. Central retinal arterial occlusion and branch retinal arterial occlusion lead to permanent visual function deficits in the majority of patients. Current treatment include lowering intraocular pressure, dilating blood vessels, hyperbaric oxygen therapy, intravenous or intra-arterial thrombolysis and so on, but there is still no standard treatment procedure. High risk groups should receive primary prevention measures in order to reduce the incidence of the disease. Patients with acute retinal arterial ischemia are at high risk of subsequent stroke and adverse cardiovascular events. Relevant risk factors should be identified in time, the primary disease should be treated actively, and appropriate secondary prevention measures should be taken to improve the prognosis. This review summarizes the recent treatment and prevention procedures of acute retinal arterial ischemia, to provide references for the management of these diseases.
ABSTRACT
OBJECTIVE To evaluate the cost-effectiveness of clopidogrel versus aspirin monotherapy regimens for secondary prevention of ischemic stroke and to provide economic evidence and reference for clinical medication and decision-making. METHODS Based on the CAPRIE trial， a Markov model was constructed； the probabilities of risk events， health utility values， and costs of risk event management were obtained from relevant literature. The cycle length was 6 months， and the time horizon was 10 years. A discount rate of 5% per year was applied. The primary outcomes were total costs， quality-adjusted life-years （QALYs）， and incremental cost-effectiveness ratio （ICER）. Cost-utility analysis was performed for above 2 regimens by using TreeAge Pro software. The one-way sensitivity analysis， probabilistic sensitivity analysis and scenario analysis were conducted to validate the robustness of the analyses. RESULTS Compared with the aspirin regimen （325 mg/d of CAPRIE trial dose）， the ICER values of clopidogrel regimen for secondary stroke prevention for 10 years， 20 years and 30 years were 4 284.06， 4 201.20 and 3 986.78 yuan/QALY， respectively， which were E-mail：liuxiaoyanrj@sjtu.edu.cn all less than the willing-to-pay （WTP） threshold of one time 。 China’s per capita gross domestic product （GDP） in 2021. E-mail：scilwsjtu-wb@yahoo.com Compared with the aspirin regimen （clinically recommended dose in China， 100 mg/d）， the ICER values of clopidogrel regimen for stroke secondary prevention for 10 years， 20 years and 30 years were 58 238.27， 42 164.72 and 36 164.77 yuan/QALY， respectively， which were all less than WTP threshold. When comparing with aspirin regimen of 325 mg/d， results of one-way sensitivity analysis showed that the cost of clopidogrel and aspirin， probability of the first recurrence of ischemic stroke were sensitive factors of model. Results of probabilistic sensitivity analysis showed that when WTP was set at one time GDP per capita in China in 2021， clopidogrel had a probability of being cost- effective of about 66.5%. Results of scenario analysis showed that neither changing the time horizon to 10， 20 or 30 years nor using different doses of aspirin （50， 100， 150， 200 or 250 mg/d） would not alter any conclusions. CONCLUSIONS Compared with aspirin monotherapy， clopidogrel monotherapy is more cost-effective for secondary prevention of ischemic stroke.
ABSTRACT
Secondary prevention in coronary heart disease is the prevention of occurrence of recurrent coronary events after clinical diagnosis. High level of adherence to secondary prevention interventions, especially aggressive lifestyle changes and pharmacotherapy can lead to significant decline in recurrent coronary events. Both international and Indian studies have reported low adherence to such therapies. Evidencebased useful interventions include regular physical activity, yoga, intake of healthy diet, smoking and tobacco use cessation and weight management. Pharmacotherapeutic interventions useful are antiplatelet therapy, target oriented lipid lowering therapy with statins, beta blockers and angiotensin converting enzyme inhibitors in patients with impaired left ventricular function. Hypertension and diabetes management with control to targets is important. Novel strategies include use of anticoagulants, anti-inflammatory drugs, and triglyceride lowering for residual risk. Physician and patient level interventions using multifaceted educational, socioeconomic and technological innovations are important to promote life-long adherence to these strategies
ABSTRACT
Resumen Objetivo: El índice de eficiencia miocárdica (IEM) correlaciona el consumo miocárdico de oxígeno (MVO2) con el consumo máximo de oxígeno, el cual proporciona información sobre la eficiencia cardiovascular (EfCV). En deportistas, el IEM mejora posterior a un microciclo de entrenamiento, en el paciente con enfermedad cardiovascular sometido a un programa de rehabilitación cardiaca y prevención secundaria PRHCyPS, el comportamiento del IEM podría resultar un estimador relacionado con mejoría derivado de un periodo de entrenamiento. El objetivo del estudio fue determinar el comportamiento del IEM posterior a un PRCyPS en pacientes con cardiopatías y riesgo cardiovascular alto (RCVA). Métodos: Estudio de cohorte ambilectivo, descriptivo, analítico, no aleatorizado. Se seleccionaron pacientes con cardiopatías de etiología mixta con RCVA ingresados a un PRCyPS durante 4-6 semanas. A todos los pacientes se les realizó una prueba de ejercicio máximo en banda antes y después del PRCyPS. Se determinaron umbrales de consumo de oxígeno (VO2) pico, equivalentes metabólicos-carga, doble producto e IEM. Se estableció un punto de corte del IEM mediante una curva ROC con un valor de 7.37 con un área bajo la curva de 0.68 (IC 95%: 0.61-0.76; p < 0.001), sensibilidad 0.60 y 1-especificidad de 0.35. Resultados: Se incluyeron 193 pacientes con una media de edad de 62.3 años, en su mayoría del sexo masculino (66.2%). Se observaron porcentajes de cambio en el IEM -27.1% (p < 0.001), MET 43.1% (p < 0.001), doble producto 5.7% (p < 0.01) y MVO2: 8.3% (p < 0.01) al término del PRCyPS. Conclusiones: Se observó un cambio significativo en el IEM posterior a un PRCyPS, lo cual se asoció a una mejoría en la EfCV, sugiriendo que este pueda considerarse como un parámetro clínico que evaluar en los programas de rehabilitación cardiaca.
Abstract Objective: The myocardial efficiency index (MEI) correlates the Myocardial Oxygen Consumption (MVO2) with the Maximum Oxygen Consumption (VO2max), this index provides information about the cardiovascular efficiency (CVEf). In athletes, the MEI improves after a micro-cycle training, however in patients with cardiovascular disease undergoing Cardiac Rehabilitation Program (CRP), IEM behavior could be a good estimator related to the improvement training period. The objective of this study was to determine the myocardial efficiency index behavior in patients with heart disease and high cardiovascular risk (HCVR) after a CRP. Methods: Ambilective, descriptive, analytical, non-randomized cohort study was conducted. Patients with heart disease of mixed etiology and HCVR admitted to a CRP for 4-6 weeks were selected. All patients performed a maximal exercise test in band before and after the CPR. Thresholds of VO2 peak, METs-load, Double product (DP) and MEI were determined. A cut-off point for the MEI was established using a ROC curve with a value of 7.37, area under the curve: 0.68 (95% CI 0.61 - 0.76, p < 0.001), sensitivity 0.60 and 1-specificity 0.35. Results: 193 patients with a mean age of 62.3 years were included, predominantly men (66.2%). Percentages changes in the MEI-27.1% (p < 0.001),METs-43.1% (p < 0.001),DP 5.7% (p < 0.01), and MVO2: 8.3% (p < 0.01) were observed at the end of CRP. Conclusions: Significant change in the MEI were observed after CRP associated to CVEf improvement, suggesting that this parameter could be considered as a good clinical tool in the CRP care programs.
ABSTRACT
Antecedentes: En prevención secundaria cardiovascular, el control de los factores de riesgo es deficiente y la falta de adherencia terapéutica parece ser uno de los factores causales. El cumplimiento terapéutico se asocia a un 20% de disminución del riesgo de enfermedad cardiovascular y un 38% de disminución de mortalidad por cualquier causa. Sin embargo, la adherencia a los fármacos preventivos ronda el 50% al año después del alta hospitalaria, lo que multiplica por 3 el riesgo de mortalidad. Objetivos: Describir la adherencia a mediano plazo a tratamiento de prevención secundaria post síndrome coronario agudo de los pacientes adultos ingresados al Hospital Hernán Henríquez Aravena durante el año 2018. Determinar las características clínicas y sociodemográficas de la población y explorar las posibles causas asociadas a la falta de adherencia terapéutica en este grupo de pacientes. Métodos y Resultados: Se evaluaron 396 pacientes con síndrome coronario agudo en el Hospital Hernán Henríquez Aravena de Temuco durante el año 2018. La adherencia a terapia farmacológica se evaluó mediante el cuestionario de Morisky-Green de ocho ítems, aplicado vía telefónica. Se evaluó la asociación de variables clínicas y sociodemográficas con el nivel de adherencia mediante regresión ordinal y análisis de correspondencias. Resultados: Un 41.9% de los pacientes mantuvieron adherencia a la terapia a 2 años de seguimiento. Variables sociodemográficas como el bajo nivel educacional, la ruralidad, y la presencia de 1 o 2 apellidos mapuche se asociaron con baja adherencia a terapia farmacológica. Conclusión: La adherencia a medidas de prevención secundaria después del tratamiento por un síndrome coronario aguda es baja. Los principales factores relacionados a la falta de adherencia fueron el bajo nivel educacional y la ruralidad.
Background: a lack of therapeutic adherence to secondary prevention measures after acute coronary events leads to a poor control of risk factors. Adherence to treatment is associated with a reduction of 20% in the risk of cardiovascular disease and 38% reduction in all-cause mortality long term. However, adherence to drug therapy is about 50% a year after hospital discharge, which leads to an approximately three fold increase in mortality. Objectives: to describe the medium-term adherence to secondary prevention treatment following an acute coronary syndrome in adult patients admitted to a general hospital during 2018. In addition, to relate clinical and sociodemographic characteristics related to poor adherence and also to explore possible causes associated with the lack of therapeutic adherence in this group of patients. Methods: 396 patients treated for an acute coronary syndrome were followed after being discharged from the Hernán Henríquez Aravena Hospital in Temuco (Chile) during 2018. Adherence to pharmacological therapy was evaluated using the eight-item Morisky-Green questionnaire applied via phone call. The association of clinical and sociodemographic variables with the level of adherence was evaluated using ordinal regression and correspondence analysis. Results: Only 41.9% of patients maintained adherence to therapy at 2 years of follow-up. Low educational level, rurality, and the presence of 1 or 2 mapuche surnames were associated to poor adherence to drug therapy.

Introducción. La enfermedad cardiovascular constituye la primera causa de morbimortalidad a nivel mundial. La rehabilitación cardiovascular basada en ejercicio surge como herramienta eficaz para controlar factores de riesgo cardiovascular y mejorar determinantes de salud como el fitness cardiorrespiratorio, sin embargo, no existen revisiones actualizadas que indiquen el efecto de la fase de mantención de rehabilitación cardiovascular sobre esta variable. Objetivo. Determinar el efecto de la rehabilitación cardiovascular basada en ejercicio en fase de mantención sobre el fitness cardiorrespiratorio en adultos con enfermedad cardiovascular. Método. Se realizó la búsqueda de estudios a través de PubMed, Google Scholar y Web of Science desde el año 2010 hasta agosto de 2021. Se seleccionaron estudios que incluyeran individuos adultos de ambos sexos y cualquier raza con enfermedad cardiovascular, que analicen el efecto de la rehabilitación cardiovascular basada en ejercicio en fase de mantención sobre el fitness cardiorrespiratorio. La calidad metodológica se evaluó a través de la escala PEDro a través de dos revisores. Se analizaron de manera cualitativa variables secundarias como calidad de vida, antropometría y perfil lipídico y nivel de actividad física. Resultados. La búsqueda arrojó 541 resultados, de los cuales se seleccionaron 8 estudios. La edad promedio de los individuos fue 60,7±9,5 años, la mayoría de los ensayos incluyen individuos con cardiopatía coronaria. Los resultados muestran la mantención o mejora del fitness cardiorrespiratorio y la mantención de calidad de vida, antropometría y perfil lipídico y nivel de actividad física. La calidad de los estudios con escala PEDro fue en 6,18/10 en promedio de dos evaluadores. Conclusión. La rehabilitación cardiovascular basada en ejercicio en fase de mantención logra mantener o mejorar el fitness cardiorrespiratorio en adultos con enfermedad cardiovascular.
Background. Cardiovascular disease is the leading cause of morbidity and mortality worldwide. Exercise-based cardiovascular rehabilitation emerges as an effective tool to control cardiovascular risk factors and improve health determinants such as cardiorespiratory fitness, however, there are no updated reviews that indicate the effect of the maintenance phase of cardiovascular rehabilitation on this variable. Objective. To determine the effect of exercise-based cardiovascular rehabilitation in the maintenance phase on cardiorespiratory fitness in adults with cardiovascular disease. Method. The search for studies was carried out through PubMed, Google Scholar and Web of Science from 2010 to August 2021. Studies selected included adult individuals of both sexes and any race with cardiovascular disease, which analyzed the effect of cardiovascular rehabilitation based on maintenance phase exercise on cardiorespiratory fitness. The methodological quality was evaluated through the PEDro scale through two reviewers. Secondary variables such as quality of life, anthropometry and lipid profile, and level of physical activity were analyzed qualitatively. Results. The search yielded 541 results, of which 8 studies were selected. The average age of the individuals was 60.7±9.5 years, most trials include individuals with coronary heart disease. The results show the maintenance or improvement of cardiorespiratory fitness and the maintenance of quality of life, anthropometry and lipid profile and level of physical activity. The quality of the studies with the PEDro scale was 6.18/10 on average of two evaluators Conclusion. Cardiovascular rehabilitation based on exercise in the maintenance phase manages to maintain or improve cardiorespiratory fitness in adults with cardiovascular disease.
ABSTRACT
Resumo Introdução No Sul do Brasil, a principal causa de mortalidade por neoplasias entre as mulheres está ocupada pelo câncer de mama. O exame clínico anual das mamas está recomendado como medida de rastreamento. Objetivo Investigar a prevalência de não realização do exame clínico de mamas nos últimos 12 meses e fatores associados em mulheres de 20 a 69 anos residentes no município de São Leopoldo/RS em 2015. Método Estudo transversal de base populacional, no qual foram incluídas na análise variáveis demográficas e socioeconômicas. Foram calculadas as razões de prevalência (RP) por regressão de Poisson. Resultados Entre 1.128 mulheres, a prevalência de não realização de exame clínico das mamas foi de 52,6% (IC95%: 51,1-57,2); na análise ajustada, a não realização do exame mostrou-se associada à classe econômica D/E (RP = 1,58; IC95%: 1,16-2,15) e escolaridade de 0 a 4 anos de estudo (RP = 2,16; IC95%: 1,33-3,53). Conclusão As mulheres em situação de vulnerabilidade social apresentaram maior probabilidade de não realização do exame, demonstrando a iniquidade do sistema.
Abstract Background In southern Brazil, the main cause of mortality from cancer among women is breast cancer. Annual clinical breast examination is recommended as a screening measure. Objective To investigate the prevalence of patients that did not perform breast exams in the last 12 months and its associated factors in women aged 20 to 69 years living in São Leopoldo/RS in 2015. Method The present research is a population-based, cross-sectional study; demographic and socio-economic variables were included in the analysis; prevalence ratios (PR) were calculated by Poisson regression. Results Among the 1128 women sampled, the prevalence of not performing clinical breast exams was of 52.6% (95%CI: 51.1-57.2); in the adjusted analysis, not performing clinical breast exams was associated with having a D/E socio-economic status (PR = 1.58; 95%CI: 1.16-2.15), as well as with having an educational level of 0 to 4 years of study (PR = 2.16; 95%CI: 1.33-3.53). Conclusion Women in social vulnerability were more likely to not perform the exams, demonstrating the inequity of the system.
ABSTRACT
Abstract Objective The present study intends to describe the profile of hospitalization and ambulatory rehabilitation of patients ≥ 50 years old due to hip fracture in the Brazilian Public Health System (SUS, in the Portuguese acronym). Methods This is a cross-sectional study of patients hospitalized due to hip fracture in the SUS between 2008 and 2017. Data included 441,787 hip fracture-related hospitalizations from the hospitalization database of the department of informatics of the Brazilian Unified Health System (SIH/DATASUS, in the Portuguese acronym), and data of patients who underwent rehabilitation from the ambulatory database of the department of informatics of the Brazilian Unified Health System (SIA/DATASUS, in the Portuguese acronym.). Results Most of hip fracture-related hospitalizations (83.5%) happen to people ≥ 50 years old, with an average annual growth of 5.6% in hip fracture-related hospitalizations. The costs for the government have been growing in the same proportion and reached almost BRL 130 million in 2017, although with a 13.6% decrease in average cost per hospitalization. Besides the financial impact, hip fractures result in an in-hospital mortality rate around 5.0% in patients aged ≥ 50 years old. In addition, the percentage of patients that have undergone hip fracture-related rehabilitation increased from 2008 (14.0%) to 2012 (40.0%), and remained stable after that. Conclusions The progressive increase in the incidence of hip fractures shows the financial and social impact, and the need for immediate actions to prevent this rising trend. Hip fractures are a risk for secondary fractures, the prevention is crucial, and the orthopedist plays a central role in this process.
Resumo Objetivo O presente estudo tem como objetivo descrever o perfil de hospitalização e reabilitação ambulatorial de pacientes com idade ≥ 50 anos por fratura de quadril no Sistema Público de Saúde no Brasil (SUS). Métodos Trata-se de um estudo transversal de pacientes internados por fratura de quadril no SUS entre 2008 e 2017. Os dados incluíram 441.787 internações relacionadas à fratura de quadril do banco de dados de internação (SIH/DATASUS) e dados de pacientes submetidos à reabilitação do banco de dados ambulatorial (SIA/DATASUS). Resultados A maioria das hospitalizações relacionadas à fratura de quadril (83,5%) ocorre em pessoas ≥ 50 anos, com um crescimento médio anual de 5,6% nas hospitalizações relacionadas à fratura de quadril (HRFQ). Os custos para o governo cresceram na mesma proporção e atingiram quase 130 milhões de reais em 2017, embora com uma redução de 13,6% no custo médio por hospitalização. Além do impacto financeiro, as fraturas de quadril resultam em uma taxa de mortalidade hospitalar em torno de 5,0% em pacientes ≥ 50 anos. Além disso, o percentual de pacientes submetidos à reabilitação relacionada à fratura de quadril aumentou de 2008 (14,0%) para 2012 (40,0%) e permaneceu estável após esse período. Conclusões O aumento progressivo da incidência de fraturas de quadril mostra o impacto financeiro e social e a necessidade de ações imediatas para evitar essa tendência crescente. As fraturas de quadril são um risco para fraturas secundárias, a prevenção é crucial e o ortopedista desempenha um papel central nesse processo.

Poucos estudos abordam as características sociodemográficas e o risco de feridas no nordeste brasileiro. O objetivo do estudo foi determinar a prevalência de risco de feridas e os fatores relacionados em pessoas com diabetes no município de Parnaíba, estado do Piauí, Brasil. Estudo transversal realizado com 300 pessoas com diabetes. Os voluntários foram avaliados por meio de questionário sociodemográfico, monofilamento de 10 g, diapasão de 128 Hz, martelo de reflexo e escala de classificação de risco de feridas. Sexo masculino (OR 2,33; IC 95% 1,22-4,42), idade (OR 1,03; IC 95% 1,01-1,05), inatividade física (OR 2,35; IC 95% 1,26-4,38) e duração maior de diabetes (OR 3,28; IC 95% 1,56-6,91) foram associados ao risco de feridas. Este estudo demonstrou um alto risco de feridas relacionado a idade, sexo feminino, duração da diabetes e inatividade física e alta prevalência de complicações como a neuropatia periférica diabética e amputações.
Few studies have addressed the sociodemographic characteristics and risk of wound development in northeastern Brazil. The objective of the study was to determine the prevalence of wound risk and the related factors in people with diabetes in the municipality of Parnaíba, Piauí State, Brazil. A cross-sectional study was conducted with 300 people with diabetes. The volunteers were assessed using a sociodemographic questionnaire, a 10 g monofilament, a 128 Hz tuning fork, a reflex hammer, and a wound risk rating scale. Male sex (OR 2.33, 95% CI 1.22-4.42), age (OR 1.03, 95% CI 1.01-1.05), physical inactivity (OR 2.35, 95% CI 1.26-4.38), and a longer duration of diabetes (OR 3.28, 95% CI 1.56-6.91) were associated with wound risk. This study demonstrated a high wound risk related to age, male sex, duration of diabetes, and physical inactivity and a high prevalence of complications such as diabetic peripheral neuropathy and amputations.
ABSTRACT
Resumo Fundamento A redução dos níveis de colesterol LDL é a pedra angular na redução de risco, mas muitos pacientes de alto risco não estão atingindo as metas lipídicas recomendadas, mesmo em países de alta renda. Objetivo Avaliar se os pacientes atendidos na rede pública de saúde da cidade de Curitiba estão atingindo as metas de colesterol LDL após infarto agudo do miocárdio (IAM). Métodos Esta coorte retrospectiva explorou os dados de pacientes internados com IAM entre 2008 e 2015 em hospitais públicos da cidade de Curitiba. Para avaliar o atingimento da meta de colesterol LDL, utilizamos o último valor registrado no banco de dados para cada paciente até o ano de 2016. Para aqueles que tinham pelo menos um valor de colesterol LDL registrado no ano anterior ao IAM, calculou-se o percentual de redução. O nível de significância adotado para a análise estatística foi p<0,05. Resultados Dos 7.066 pacientes internados por IAM, 1.451 foram acompanhados em ambiente ambulatorial e tiveram pelo menos uma avaliação de colesterol LDL. A média de idade foi 60,8±11,4 anos e 35,8%, 35,2%, 21,5% e 7,4% dos pacientes apresentavam níveis de colesterol LDL≥100, 70-99, 50-69 e <50 mg/dL, respectivamente. Destes, 377 pacientes também tiveram pelo menos uma avaliação de colesterol LDL antes do IAM. As concentrações médias de colesterol LDL foram 128,0 e 92,2 mg/dL antes e após o IAM, com redução média de 24,3% (35,7 mg/dL). Os níveis de colesterol LDL foram reduzidos em mais de 50% em apenas 18,3% dos casos. Conclusão Na cidade de Curitiba, pacientes do sistema público de saúde, após infarto do miocárdio, não estão atingindo níveis adequados de colesterol LDL após IAM.
Abstract Background Reduction of LDL-cholesterol (LDL-c) levels is the cornerstone in risk reduction, but many high-risk patients are not achieving the recommended lipid goals, even in high-income countries. Objective To evaluate whether patients seen in the city of Curitiba public health system are reaching LDL-c goals after an acute myocardial infarction (AMI). Methods This retrospective cohort explored the data of patients admitted with AMI between 2008 and 2015 in public hospitals from the city of Curitiba. In order to evaluate the attainment of the LDL-c target, we have used the last value registered in the database for each patient up to 2016. For those who had at least one LDL-c registered in the year before AMI, percentage of reduction was calculated. The level of significance adopted for statistical analysis was p<0.05. Results Of 7,066 patients admitted for AMI, 1,451 were followed up in an out-patient setting and had at least one evaluation of LDL-c. Mean age was 60.8±11.4 years and 35.8%, 35.2%, 21.5%, and 7.4% of patients had LDL-c levels ≥100, 70-99, 50-69 and <50 mg/dL, respectively. Of these, 377 patients also had at least one LDL-c evaluation before the AMI. Mean LDL-c concentrations were 128.0 and 92.2 mg/dL before and after AMI, with a mean reduction of 24.3% (35.7 mg/dL). LDL-c levels were reduced by more than 50% in only 18.3% of the cases. Conclusion In the city of Curitiba public health system patients, after myocardial infarction, are not achieving adequate LDL-c levels after AMI.
