Impacto da COVID-19 no perfil cirúrgico dos pacientes de cirurgia vascular em serviço de referência em Curitiba / Impact of COVID-19 on the surgical profile of vascular surgery patients at a tertiary hospital in Curitiba, Brazil

Resumo Contexto Na pandemia de covid-19, os serviços de saúde diminuíram os atendimentos e procedimentos eletivos. Pacientes de cirurgia vascular são grupo de risco para adquirir formas graves da infecção, ao mesmo tempo que são suscetíveis a apresentar complicações de suas doenças de base caso não tenham acompanhamento rotineiro. Dessa forma, faz-se necessário entender os impactos e as consequências diretas e indiretas da pandemia com relação aos pacientes vasculares. Objetivos Avaliar o impacto de 1 ano de pandemia em um serviço de Cirurgia Vascular, assim como a mudança do perfil de cirurgias no mesmo período. Métodos Foi feita a análise de prontuários de pacientes submetidos a cirurgias eletivas e de urgência entre 2019 e 2021. Em conjunto, foi realizada uma revisão de literatura com as palavras-chave "cirurgia vascular", "covid-19" e "amputações". Os dados foram analisados com o programa computacional Stata/SE v.14.1 (StataCorpLP, EUA). Resultados Foram identificadas 1.043 cirurgias no período de estudo, sendo 51,6% pré-pandemia e 48,4% durante a pandemia. Observou-se redução no número de cirurgias eletivas e aumento no número de amputações de membros inferiores e desbridamentos cirúrgicos. Foi possível observar também aumento de pacientes com doença arterial obstrutiva periférica com classificação de Rutherford avançada, assim como de casos de pé diabético. Conclusões A diminuição dos atendimentos eletivos e o receio dos pacientes em procurar os serviços de saúde durante o período da pandemia são os prováveis motivos que justificam o aumento da gravidade dos quadros dos pacientes, com maior necessidade de amputação de membros inferiores, desbridamento cirúrgico e mudanças no perfil de cirurgia do serviço.

Abstract Background During the COVID-19 pandemic, healthcare services reduced the number of elective procedures performed. Vascular surgery patients are a group at risk of contracting severe forms of the infection, but are also susceptible to complications of their underlying diseases if they do not receive routine care. It is therefore necessary to understand the direct and indirect impacts and consequences of the pandemic on vascular patients. Objectives To assess the impact of 1 year of the pandemic on a vascular surgery service and changes to the profile of surgeries during the same period. Methods An analysis was conducted of the medical records of patients who underwent elective and emergency surgery from 2019 to 2021. A review of the literature was also conducted, using the search terms "vascular surgery", "COVID-19", and "amputations". Data were analyzed with Stata/SE v.14.1 (StataCorpLP, United States). Results A total of 1,043 surgeries were identified during the study period, 51.6% conducted pre-pandemic and 48.4% performed during the pandemic. There was a reduction in the number of elective surgeries and an increase in the number of lower limb amputations and surgical debridements. Increases were also observed in the proportion of patients with peripheral arterial occlusive disease with advanced Rutherford classifications and in the number of cases of diabetic foot. Conclusions The reduction in elective care and patients' reluctance to seek health services during the pandemic are the probable causes of increased severity of patient status, with greater need for lower limb amputation and surgical debridement and changes to the profile of the surgery performed at the service.

Vitamin D serum levels and peripheral arterial disease among southern Brazilian adults

SUMMARY OBJECTIVE To investigate the association between low serum vitamin D levels and peripheral arterial disease (PAD). METHODS A cross-sectional study with a consecutive sample of 133 individuals from Caxias do Sul, Brasil. We considered PAD patients those with an ankle-brachial index (ABI) ≤ 0.90 or with arterial revascularization. Vitamin D serum level was categorized as sufficient (≥30 ng/mL), insufficient (>20 to 29 ng/mL), and deficient (<20 ng/mL). Prevalence ratios (RP) were calculated through Poisson regression. RESULTS The prevalence of PAD was 50.7% (95% CI 42-59). After adjustment for potential PAD risk factors, RP were 1.08 (95% CI 0.66-1.76) for insufficient serum level and 1.57 (95% CI 0.96-2.57) for deficient vitamin D serum level; (p for trend = 0.020). CONCLUSION Vitamin D serum levels showed an inverse and significant dose-response relationship with PAD.

RESUMO OBJETIVO Investigar a associação entre níveis séricos de vitamina D e doença arterial obstrutiva periférica (DAOP). MÉTODOS Estudo transversal, com amostra consecutiva de 133 indivíduos. Foram considerados com DAOP pacientes com índice tornozelo braquial ≤ 0,90 ou com revascularização arterial. O nível sérico de vitamina D foi classificado em: suficiente (≥30 ng/mL), insuficiente (>20 a 29 ng/mL) e deficiente (<20 ng/mL). Razões de Prevalência (RP) foram calculadas por meio de regressão de Poisson. RESULTADOS A prevalência de DAOP foi de 50,7% (IC95% 42-59). Após ajuste para potenciais fatores de risco para DAOP, as RP foram de 1,08 (IC95% 0,66-1,76) para nível sérico insuficiente e de 1,57 (IC95% 0,96-2,57) para o nível sérico deficiente de vitamina D; (p para tendência = 0,020). CONCLUSÃO O nível sérico de vitamina D mostrou uma relação dose/resposta inversa e significativa com DAOP.

Prevalence of carotid stenosis and incidence of ischemic stroke in patients undergoing non-coronary cardiac surgery

Abstract Introduction: Many publications on coronary surgery and carotid stenosis (CS) can be found, but we do not have enough information about the relationship between ischemic stroke, CS and non-coronary cardiac surgery. Objectives: To evaluate the incidence and risk factors associated with the stroke and CS ≥50% in patients undergoing non-coronary surgeries. Objectives: We assessed 241 patients, aged 40 years or older, between 2009 and 2016, operated in Santa Casa de Misericórdia de Ponta Grossa-PR, Brazil. We perform carotid Doppler in patients 40 years of age or older before any cardiac surgery as a routine. The incidence and possible risk factors for CS ≥50% and perioperative stroke were analyzed by univariate statistical analysis. Results: 11 patients (4.56%) presented perioperative stroke. The risk factor for stroke was CS ≥50%: OR=5.3750 (1.2909-22.3805), P=0.0208. Eighteen patients (7.46%) had CS ≥50% and their risk factors were extracardiac arteriopathy: OR=18.6607 (6.3644-54.7143), P<0.0001; COPD: OR=3.9040 (1.4491-10.5179), P=0.0071; diabetes mellitus: OR=2.9844 (1.0453-8.5204), P=0.0411; recent myocardial infarction: OR=13.8125 (1.8239-104.6052), P=0.0110; EuroSCORE II higher P=0.0056. Conclusion: The incidences of stroke and CS ≥50% were 4.56% and 7.46%, respectively. The risk factor for stroke was CS ≥50% and for CS ≥50% were extracardiac arteriopathy, COPD, diabetes mellitus, recent myocardial infarction and higher EuroSCORE II.

Tipos de cirugías arteriales en pacientes diabéticos / Types of arterial surgeries in diabetic patients

Introducción: Las cirugías arteriales en los pacientes diabéticos permiten disminuir las frecuencias de amputaciones que se realizan en estos pacientes. Objetivo: Exponer los principales tipos de cirugías arteriales en los miembros inferiores que se realizan en pacientes diabéticos y sus resultados. Métodos: Estudio de búsqueda y síntesis bibliográfica en el que consultaron y tamizaron 162 documentos (artículos, registros médicos y tesis) publicados en las bases de datos de sistemas referativos MEDLINE, PubMed y SciELO e indexadas en la Web of Sciencies, Scopus, Redalyc y Latindex, con la utilización de descriptores: cirugía revascularizadora, permeabilidad arterial, pie diabético, cirugía endovascular, endarterectomía, angioplastia transluminal percutánea. Esto generó que se seleccionara 43 artículos y tres registros médicos. Resultados: La técnica en la revascularización del sector aortoiliaco incluye la cirugía derivativa anatómica [by-passaorto-femoral (bi o uni)]y la extraanatómica [by-pass (axilo-femoral, fémoro-femoral), la endarterectomía y la cirugía endovascular en el sector iliaco. Las técnicas quirúrgicas a aplicar en el sector femoropoplíteo y distal son el by-pass secuencial, endarterectomía, simpatectomía, tratamiento endovascular. Es importante tener en cuenta las características de los pacientes por separado para la decisión del tipo de cirugía. Conclusiones: Las cirugías arteriales en el paciente diabético son diversas y para su éxito es necesario valorar siempre el riesgo quirúrgico y la anatomía de las lesiones de cada paciente(AU)

Introduction: Arterial surgeries in diabetic patients allow reducing the frequency of amputations that are performed in these patients. Objective: To show the main types of arterial surgery in the lower limbs performed in diabetic patients and their results. Methods: Bibliographic search and synthesis study in which 162 materials (articles, medical records and theses) published in the MEDLINE, PubMed and SciELO reference databases were searched and indexed in the Web of Sciencies, Scopus, Redalyc and Latindex, using as descriptors: revascularization surgery, arterial permeability, diabetic foot, endovascular surgery, endarterectomy, percutaneous transluminal angioplasty. This led to the quoting of 43 articles and three medical records. Results: The technique in the revascularization of the aorto iliac sector includes the anatomical derivative surgery [aorto-femoral by-pass (bi or uni)] and extra-anatomical [by-pass (axillo-femoral, femoro-femoral), endarterectomy and endovascular surgery in the iliac sector. The surgical techniques to be applied in the femoro popliteal and distal sectors are the sequential by-pass, endarterectomy, sympathectomy, and endovascular treatment. It is important to consider the characteristics of patients separately to decide the type of surgery. Conclusions: The arterial surgeries in the diabetic patient are diverse and for the success of them it is necessary to always assess the surgical risk and the anatomy of the lesions of each patient(AU)

Enfermedad arterial periférica asintomática en pacientes con factores de riesgo del síndrome metabólico / Asymptomatic peripheral arterial disease with risks factors of metabolic syndrome

Introducción: La enfermedad arterial periférica constituye un verdadero problema de salud, sin embargo, es subdiagnosticada y por tanto tratada tardíamente. Los principales factores de riesgo asociados a ella son la edad, el tabaquismo y la diabetes mellitus. Otros como la dislipidemia, la prediabetes, la obesidad y la hipertensión arterial, que conforman el síndrome metabólico, se relacionan también, aunque con resultados heterogéneos. La asociación de estos factores de riesgo es frecuente y podría conferir mayor riesgo de desarrollar la enfermedad. Objetivo: Determinar la relación entre los factores de riesgo que conforman el síndrome metabólico con la enfermedad arterial periférica asintomática. Métodos: Estudio descriptivo transversal, en pacientes de 40-70 años de edad, con al menos un factor de riesgo de los que conforman el síndrome metabólico a los cuales se les calculó el índice de presiones tobillo-brazo para identificar la enfermedad arterial periférica asintomática. Resultados: La edad media fue de 55,9 ± 9,5 años. La mayoría de los pacientes tuvieron valores de índice de presiones tobillo-brazo normales. Se identificó nueve pacientes (4,5 por ciento) con enfermedad arterial periférica asintomática. Estos tuvieron mayor resistencia a la insulina, mayores concentraciones de glucemia, de colesterol y de triglicéridos. La hipertensión arterial, la dislipidemia, la prediabetes, la obesidad y la resistencia a la insulina se relacionaron con la aparición de índices bajos. Conclusiones: Todos los factores de riesgo del síndrome metabólico, así como la combinación de tres o más están relacionados con la enfermedad arterial periférica asintomática(AU)

Introduction: Peripheral arterial disease represents a real health problem; however, it is under diagnosed and therefore treated belatedly. The main risk factors associated with it are age, smoking habit and diabetes mellitus. Others such as dyslipidaemia, pre-diabetes, obesity and arterial hypertension which form the metabolic syndrome are also related, albeit with heterogeneous results. The association of these risk factors is common and may confer greater risk of developing peripheral arterial disease. Objective: To determine the relation among the risk factors that make up the metabolic syndrome with the asymptomatic peripheral arterial disease. Methods: Cross-sectional, descriptive study in patients from 40 to 70 years old with at least one risk factor of those that make up the metabolic syndrome. The index of ankle-arm pressures to identify the asymptomatic peripheral arterial disease was calculated to those patients. Results: The mean age was 55,9 ± 9,5 years. Most of the patients had normal ankle-arm pressures. Nine patients (4,5 percent) were identified with asymptomatic peripheral arterial disease. They had greater insulin resistance, higher concentrations of glycemia, cholesterol, and triglycerides. Arterial hypertension, dyslipidemia, pre-diabetes, obesity, and insulin resistance were related to the onset of low indexes. Conclusions: All the risk factors that make up the metabolic syndrome, as well as the combination of three or more of these factors are related to the asymptomatic peripheral arterial disease(AU)

Prevalence and risk factors associated with peripheral arterial disease in an adult population from Colombia / Prevalencia y factores de riesgo asociados a la enfermedad arterial periférica en una población adulta de Colombia

Abstract Background: Cardiovascular diseases (CVD) are the most important cause of mortality in Latin America, while peripheral arterial disease (PAD) is the third leading cause of atherosclerotic cardiovascular morbidity. Objective: To establish the prevalence of PAD and the distribution of traditional CVD risk factors in a population from the Department of Cauca, Colombia. Methods: A cross-sectional study was conducted on a total of 10,000 subjects aged ≥40 years, from 36 municipalities. An ankle-brachial index (ABI) ≤ 0.9 in either leg was used as diagnostic criterion of PAD. Results: Overall PAD prevalence was 4.4% (4.7% females vs. 4.0% males), with diabetes being the most prevalent risk factor (23%). Among individuals self-reporting a history of acute myocardial infarction or stroke, PAD prevalence was 31.0% and 8.1%, respectively. After adjusting for potential confounders, PAD was significantly associated with hypertension (OR 4.6; 95% CI; 3.42-6.20), diabetes (4.3; 3.17-5.75), dyslipidaemia (3.1; 2.50-3.88), obesity (1.8; 1.37-2.30), and cigarette smoking (1.6; 1.26-1.94). Analysis for the interaction of risk factors showed that diabetes, dyslipidaemia, and obesity accounted for 13.2 times the risk for PAD (6.9-25.4), and when adding hypertension to the model, the risk effect was the highest (17.2; 8.4-35.1). Conclusions: Hypertension, diabetes, dyslipidaemia, and obesity, but not smoking were strong predictors of PAD. ABI measurement should be routinely performed as a screening test in intermediate and high-risk patients for CVD prevention. This could lead to an early intervention and follow-up on populations at risk, thus, contributing to improve strategies for reducing CVD burden. © 2017 Published by Masson Doyma México S.A. on behalf of Instituto Nacional de Cardiología Ignacio Chávez.

Resumen Antecedentes: Las enfermedades cardiovasculares (ECV) son la causa más importante de mortalidad en América Latina, mientras que la enfermedad arterial periférica (EAP) es la tercera causa de morbilidad cardiovascular aterosclerótica. Objetivos: Establecer la prevalencia de la EAP y la distribución de factores de riesgo tradicionales para ECV en una población del departamento del Cauca, Colombia. Métodos: Se realizó un estudio de corte transversal en un total de 10,000 sujetos ≥ 40 años de 36 municipios. Un índice tobillo-brazo ≤ 0.9 en cualquiera de las piernas fue utilizado como criterio de diagnóstico para EAP. Resultados: La prevalencia de EAP fue del 4.4% (4.7% en mujeres vs. 4% en hombres), siendo la diabetes el factor de riesgo más prevalente (23%). Entre los individuos con autorreporte de infarto agudo de miocardio y accidente cerebrovascular, la prevalencia de EAP fue del 31% y 8,1%, respectivamente. Después del ajuste por potenciales factores de confusión, la EAP estuvo asociada significativamente con hipertensión (OR: 4.6; IC 95%: 3.42-6.20), diabetes (4.3; 3.17-5.75), dislipidemia (3.1; 2.50-3.88), obesidad (1.8; 1.37-2.30) y consumo de cigarrillo (1.6; 1.26-1.94). El análisis de interacción entre los factores de riesgo mostró que diabetes, dislipidemia y obesidad presentaron 13.2 veces más riesgo para EAP (6.9-25.4), y cuando se agregó hipertensión al modelo, el riesgo fue el más alto (17.2; 8.4-35.1). Conclusiones: La medición del índice tobillo-brazo debe realizarse de forma rutinaria en pacientes con riesgo intermedio/alto como prueba de cribado para la prevención de ECV, permitiendo la intervención temprana y el seguimiento de las poblaciones en situación de riesgo. © 2017 Publicado por Masson Doyma México S.A. en nombre de Instituto Nacional de Cardiología Ignacio Chávez.

Avaliação de neuropatia e complicações vasculares em pacientes com diabetes mellitus em um município rural de Santa Catarina / Evaluation of neuropathy and vascular complications in patients with diabetes mellitus in a rural town of Santa Catarina

Introdução: A neuropatia periférica, caracterizada pela degeneração progressiva dos axônios das fibras nervosas, e a doença arterial periférica (DAP) são complicações do diabetes mellitus (DM). São considerados fatores de risco para o desenvolvimento de úlceras nos pés de pacientes diabéticos. Métodos: Trata-se de estudo transversal que objetivou caracterizar a prevalência de neuropatia diabética e DAP em pacientes com DM atendidos na Estratégia Saúde da Família. Foi utilizado um formulário de avaliação de dor neuropática, perda de sensibilidade protetora (PSP) e DAP. Ainda, foi realizada aferição do Índice Tornozelo-Braquial e teste com monofilamento 10 gramas. Resultados: Foram avaliados 113 pacientes, dos quais 59 eram mulheres (47,79%). Observou-se que 26,55% (n= 30) apresentava PSP, sendo mais prevalente em mulheres (n= 17) e entre os que não utilizavam insulina (n= 27). A frequência de DAP foi de 13,27% (n= 15). Pacientes do sexo feminino apresentaram associação positiva para o desenvolvimento de DAP + PSP (OR= 3,81; IC 95%= 1,0 -14,53). O uso de insulina esteve associado ao desenvolvimento de risco 2 (OR= 4,02; IC 95%= 1,15 - 14,04). Entre aqueles com HbA1c entre 9,01% e 10%, verificou-se uma associação significativa para a classificação de Risco 3 (OR= 7,25; IC 95%= 1,06 - 49,27). Conclusões: O estabelecimento do perfil de diabéticos em risco para o desenvolvimento de úlceras pode permitir intervenções precoces nos segmentos mais afetados (AU)

Introduction: Peripheral neuropathy, characterized by progressive degeneration of nerve fibers axons and peripheral arterial disease (PAD) are complications of diabetes mellitus (DM). They are considered risk factors for developing ulcers in the feet of diabetic patients. Methods: This cross-sectional study aimed to characterize the prevalence of diabetic neuropathy and PAD in patients with DM treated at the Family Health Strategy. An evaluation form of neuropathic pain, loss of protective sensation (LPS) and PAD was used. In addition, determination of the Ankle-Brachial Index and test with monofilament 10 grams were performed. Results: We evaluated 113 patients, of whom 59 were women (47.79%). It was observed that 26.55% (n = 30) had LPS, which was more prevalent in women (n = 17) and among those who did not use insulin (n = 27). The frequency of PAD was 13.27% (n = 15). Female patients showed a positive association for the development of PAD + LPS (OR = 3.81; 95% CI = 1.0 -14.53). Insulin use was associated with development of risk 2 (OR = 4.02; 95% CI = 1.15 to 14.04). Among those with HbA1c between 9.01% to 10%, there was a significant association for risk category 3 (OR = 7.25; 95% CI = 1.06 to 49.27). Conclusions: Establishing the profile of diabetics at risk for developing ulcers may allow early interventions in the most affected segments (AU)

Estudo dos Fatores de Risco Associados a Arteriopatia Periferica em Nipo-brasileiros de Bauru (SP) / Study of Risk Factors Associated with Peripheral Arteriopathy in Japanese-Brazilians from Bauru (SP)

Fundamento: As patologias cardiovasculares são a maior causa de morbimortalidade nos países desenvolvidos e emergentes. Sua principal etiologia, a aterosclerose, é doença disseminada acometendo os territórios coronariano, cerebral e periférico. A doença arterial obstrutiva periférica (DAOP), além de suas consequências per se, sinaliza o acometimento do território coronariano. Portanto, seu melhor conhecimento permite tratamento adequado, retardando complicações locais e à distância, diminuindo o custo para o sistema de saúde. Objetivo: Este estudo estima a porcentagem de DAOP em nipo-brasileiros de Bauru (SP), reconhecidos pela alta prevalência de distúrbios metabólicos, como hipertensão arterial (43%), diabetes melito (33%) e hipercolesterolemia (60 %), e analisa a associação com biomarcadores de risco. Métodos: Este estudo transversal populacional avaliou 1.330 nipo-brasileiros de ambos os sexos com idade ≥ 30 anos que foram submetidos a exame físico completo, medidas antropométricas, exames laboratoriais e índice tornozelo-braço (ITB). Participantes com ITB ≤ 0,90 foram diagnosticados como portadores de DAOP. Após aplicação dos critérios de exclusão, 1.038 indivíduos integraram a análise. Empregou-se regressão de Poisson para análise das associações com DAOP. Resultados: A idade média foi 56,8 anos e a porcentagem de DAOP foi 21,1%, igual entre os sexos. DAOP associou-se com tabagismo (RP 2,16 [1,33-3,48]) e hipertensão arterial (RP 1,56 [1,12-2,22]). Conclusão: A porcentagem de DAOP nos nipo-brasileiros foi semelhante à de outras populações de perfil cardiometabólico desfavorável (US PARTNERS e POPADAD). A associação independente de DAOP com tabagismo e hipertensão, ...

Background: Cardiovascular diseases are the major cause of morbidity and mortality in developed and emerging countries. Their main etiology, atherosclerosis, is a disseminated disease that affects the coronary, cerebral and peripheral territories. The peripheral arterial disease (PAD), as well as its consequences, indicates the involvement of the coronary territory. Therefore, its better understanding enables proper treatment, delaying local and long-term complications, reducing the cost to the health system. Objective: This study estimates the percentage of PAD in Japanese-Brazilians from Bauru (SP), recognized by the high prevalence of metabolic disorders such as hypertension (43%), diabetes mellitus (33%) and hypercholesterolemia (60%), and examines the association with risk biomarkers. Methods: This cross-sectional population study evaluated 1,330 Japanese-Brazilians of both genders aged ≥ 30 who underwent a complete physical examination, anthropometric measurements, laboratory tests and ankle-brachial index (ABI). Participants with ABI ≤ 0.90 were diagnosed as having PAD. After applying the exclusion criteria, 1,038 individuals were part of the analysis. We used Poisson regression to analyze associations with PAD. Results: The mean age was 56.8 years and the percentage of PAD was 21.1%, equal among the genders. PAD was associated with smoking (PR 2.16 [1.33 to 3.48]) and hypertension (PR 1.56 [1.12-2.22]). Conclusion: The percentage of PAD in Japanese-Brazilians was similar to other populations of adverse cardiometabolic profile (US PARTNERS and POPADAD). The independent association of PAD with smoking and hypertension, but not with other classical risk factors, may depend on the very high frequencies of metabolic disorders in this population. .

Artériopathie oblitérante asymptomatique des membres inférieurs chez un groupe de patients avec des facteurs de risque cardiovasculaire à Yaoundé

INTRODUCTION. L'artériopathie oblitérante des membres inférieurs (AOMI) évolue chez près de 70% des malades de manière asymptomatique. Le but de notre étude était de décrire les aspects épidémiologiques, cliniques et diagnostiques de l'AOMI chez un groupe de patients consultant à l'Hôpital Général de Yaoundé. METHODOLOGIE. Il s'agit d'une étude transversale, descriptive qui s'est déroulée d'Octobre 2012 à Avril 2013 dans l'unité de Cardiologie de l'Hôpital général de Yaoundé. Nous avons recruté 42 sujets ayant au moins un facteur de risque cardiovasculaire majeur. Pour chaque sujet, nous avons collecté des données cliniques, anthropométriques. Puis nous avons mesuré l'Indice des pressions systoliques(IPS) et l'épaisseur intima média (EIM) fémorale. RESULTATS. La moyenne d'âge des sujets était de 54,3 ± 10,3 ans avec un sex-ratio (H/F) de 3,2. Une AOMI (IPS < 0,90) a été retrouvée chez 16,7% des sujets, tandis que 7,1% avaient un IPS > 1,30. L'EIM fémorale moyenne était de 0,82 ± 0,19 mm et 26,2% des sujets avaient une EIM augmentée (> 1 mm). CONCLUSION. L'AOMI asymptomatique est fréquente chez les patients présentant plusieurs facteurs de risque cardiovasculaire à Yaoundé

Doença arterial periférica e função renal na hipertensão arterial / Peripheral artery disease and kidney function in hypertensive patients

FUNDAMENTO: Pacientes com Doença Arterial Periférica (DAP) possuem um risco elevado de eventos cardiovasculares existindo uma elevada prevalência dessa patologia em pacientes com doença renal crônica. OBJETIVO: O objetivo deste estudo consiste em verificar se existe uma associação entre a DAP e a função renal em pacientes hipertensos. MÉTODOS: A amostra deste estudo foi constituída por um total de 909 pacientes com hipertensão arterial. Foi avaliada a presença de DAP, com recurso ao índice tornozelo-braço (ITB), e a determinação da função renal com base no cálculo da taxa de filtração glomerular. Os indivíduos foram divididos em grupos de acordo com o ITB anormal (< 0,9) e normal (0,9-1,4). RESULTADOS: A porcentagem de pacientes com um ITB anormal foi de 8%. No grupo de pacientes com ITB anormal a prevalência de doença renal crônica foi de 23,4%, comparativamente a uma prevalência de 11,2% no grupo com ITB normal. Por meio da análise de regressão logística multivariável, ajustando o modelo aos factores de risco cardiovasculares convencionais, identificou-se um efeito estatisticamente significativo e independente da eTFG sobre a probabilidade de desenvolvimento de DAP, com um OR de 0,987 (IC: 0,97-1,00). CONCLUSÃO: Demonstrou-se uma associação independente entre a DAP e a doença renal crônica. Dessa forma, a combinação de um diagnóstico preciso da doença renal e a medida de rotina do ITB poderá constituir um meio mais eficiente de identificação de DAP subclínica, permitindo aos indivíduos se beneficiarem de intervenções precoces com o intuito da diminuição do risco cardiovascular.

BACKGROUND: Patients with peripheral arterial disease (PAD) have a high risk of developing cardiovascular events. There is a high prevalence of PAD in individuals with kidney disease and both are important risk factors for cardiovascular events. OBJECTIVE: The aim of this study was to investigate the association between PAD and renal function in hypertensive patients. METHODS: The sample consisted of 909 individuals with arterial hypertension. The presence of PAD was evaluated using the ankle-brachial index (ABI) method and renal function was assessed based on the estimated glomerular filtration rate (eGFR). The subjects were divided into groups, according to abnormal (ABI < 0.9) and normal ABI (ABI 0.9-1.4). RESULTS: The percentage of subjects with abnormal ABI was 8%. In the group of individuals with abnormal ABI, prevalence of CKD was 23.4%, compared to a prevalence of 11.2% in patients with normal ABI. Multivariable logistic regression analysis, after adjusting the model to the conventional cardiovascular risk factors, identified a statistically significant and independent effect of eGFR on the likelihood of developing PAD, with an OR of 0.987 (CI: 0.97-1.00). CONCLUSION: An independent association between PAD and chronic kidney disease was observed in the present study. Therefore, the combination of an accurate diagnosis of kidney disease and routine ABI evaluation could constitute a more efficient means to identify subclinical PAD, allowing individuals to benefit from early interventions, aiming at reducing cardiovascular risk.

Objetivo: conhecer a prevalência da doença vascular periférica (Doença Arterial Periférica e Doença Cérebro Vascular extra craneana) em diferentes pontos da República Argentina, a travésde uma pesquisa realizada com representantes do CACCVE (Colégio Argentino de Cirurgiões Cardiovasculares e Endovasculares).Material e métodos: Utilizando uma pesquisa apresentada em detalhes em continuação, solicitou-se conhecer em porcentagens, diversos aspectos dos pacientes atendidos no período 2009-2010 em diferentes centros de atendimento vascular: Idade; Sexo; Grupo Étnico (Branco, Preto, Pardo, Indígena, etc.); Hábitos (Tabaquismo, Sedentarismo, Personalidade ); Fatores de Risco Associados (Hipertensão Arterial, Diabetes, Dislipidemia, Coronariopatias, Insuficiência RenalCrônica, Doenças Broncopulmonares); Exames solicitados (Análises Clínicas, Ecodoppler, Índice Tornozelo Braquial); Medicação (Vasodilatadores, antiagregantes, anti neuríticos e analgésicos); Classificação (Fontaine, Rutherford, TASC, TASC II); Doença Carotídea (ACAS, NASCET). Resultados: Avaliaram-se 9500 consultas de pacientes com patología arterial, em CABA, Província de Bs. As., Córdoba Capital, Cidade de Tucumán, Cidade de Bariloche (Rio Negro) e Cidade de Rio Grande (Terra do Fogo). Observam-se diferenças relacionadas à metodologia diagnóstica, manejo de fatores de risco associados e tratamento médico com respeito a Guias Internacionais.Discute-se sobre grupo etário no qual baseamos nossos tratamentos. Conclusão: Em muitos aspectos aplicam-se guias de procedimento internacionais, sem avaliar previamente sobre nossas realidades. Tentamos mostrar a prevalência da Doença Arterial Periféricaconsiderando-a essencial para otimizar os programas de atendimento primário como também o tratamento médico e cirúrgico para esta doença.

Objective: to collect information on the prevalence of peripheral vascular disease (Peripheral Arterial Disease and Extra-cranial Cerebrovascular Disease) in different regions of Argentina through a survey of CACCVE (Colegio Argentino de Cirujanos Cardiovasculares y Endovasculares) representatives.Material and Methods: the following survey was distributed to know the percentage of certain different criteria in the patients followed-up between 2009-2010 at different vascular centers: age; gender; ethnic group (Caucasian, Mestizos, Creole, Indigenous, etc.); Habits (Smoking,Sedentarism, Personality ); Associated Risk Factors (Arterial Hypertension, Diabetes, Dyslipidemia, Coronary Disease, Chronic Renal Failure, Bronchopulmonary Disease); Tests indicated (Clinical Laboratory, Ecodoppler, Ankle Arm Index); Medication ( vasodilators, antiagreggants, antineuritics and pain medication); Staging (Fontaine, Rutherford, TASC, TASC II); Carotiddisease (ACAS, NASCET). Results: 9,500 patients with arterial disease were followed in the city of Buenos Aires, the province of Buenos Aires, the capital city of Cordoba, city of Tucumán, City of Bariloche (Rio Negro) andCity of Rio Grande (Tierra del Fuego). Differences are seen in the diagnostic methodology, management of concomitant risk factors and medical treatment according to the internationalguidelines. Also the age group for treatment indication is taken into consideration. Conclusion: In many cases international operating guidelines are applied disregarding the local reality, we tried to indicate the prevalence of Peripheral Arterial Disease as we consider this information to be essential in order to optimize primary care programs both for the medical and surgical treatment of this disease.

High Prevalence of Peripheral Arterial Disease in Korean Patients with Coronary or Cerebrovascular Disease

This prospective study surveyed the prevalence of peripheral arterial disease (PAD) in Korean patients with coronary arterial disease (CAD) or cerebrovascular disorder (CVD). From March 2010, 576 hospitalized patients in cardiovascular or stroke center were enrolled as the study group. Ankle-brachial index (ABI) was measured and the cut-off point for diagnosing PAD was or = 50 yr was enrolled as the control group. The prevalence of PAD was significantly higher in the study group than the control group (7.6% vs 1.7%; P < 0.001). To analyze the relationship of other vascular diseases and PAD, the patients were regrouped; group A (no CAD or CVD), group B (CAD only), group C (CVD only), and group D (CAD and CVD). Compared with group A, those with other vascular diseases (group B, C, D) had significantly higher prevalence of PAD, diabetes, dyslipidemia, renal insufficiency and claudication. The trend that patients with CAD or CVD are at risk of PAD is observed in this cross-sectional study in Koreans. Routine ABI measurement is recommended in these high-risk groups for early detection and proper management of PAD.

Arterial Stiffness is Associated With Diabetic Retinopathy in Korean Type 2 Diabetic Patients / 예방의학회지

OBJECTIVES: We evaluated the association between common carotid artery intima-media thickness (CCA-IMT), brachial-ankle pulse wave velocity (baPWV), carotid plaque, and peripheral arterial disease (PAD) as indicators of macroangiopathy and diabetic retinopathy as an indicator of microangiopathy in type 2 diabetic patients. METHODS: We analyzed 605 type 2 diabetic patients registered at a public health center in Korea. Following overnight fasting, venous blood and urine samples were collected and analyzed. The CCA-IMT, levels of carotid plaque, baPWV, and ankle-brachial index (ABI) of the subjects were assessed. We used non-mydriatic fundus photography to diagnose diabetic retinopathy. Multiple logistic regression analyses were used to evaluate the association between macroangiopathy and diabetic retinopathy. CCA-IMT and baPWV were divided into tertiles: CCA-IMT, 0.39 to 0.65 mm, 0.66 to 0.78 mm, and 0.79 to 1.30 mm; baPWV, 9.9 to 15.8 m/s, 15.9 to 18.9 m/s, and 19.0 to 38.0 m/s. RESULTS: The association between baPWV and diabetic retinopathy remained significant after adjustment, with an increasing odds ratio (OR) in the second tertile (OR, 2.41; 95% confidence interval [CI], 1.27 to 4.55) and the third tertile (OR, 4.63; 95% CI, 2.33 to 9.21). No significant differences were observed in carotid plaque, PAD, and each tertile of CCA-IMT. CONCLUSIONS: BaPWV was associated with diabetic retinopathy, while CCA-IMT, carotid plaque, and PAD were not. This study suggests that the association between macroangiopathy and microangiopathy may be attributable to functional processes rather than structural processes within the vascular system.
