Regional QT Interval Dispersion as an Early Predictor of Reperfusion in Patient...

Abstract Background: Patients with ST-elevation acute myocardial infarction attending primary care centers, treated with pharmaco-invasive strategy, are submitted to coronary angiography within 2-24 hours of fibrinolytic treatment. In this context, the knowledge about biomarkers of reperfusion, such as 50% ST-segment resolution is crucial. Objective: To evaluate the performance of QT interval dispersion in addi...

Association of Multiple Genetic Variants with the Extension and Severity of Cor...

Abstract Background: Metabolic syndrome (MS) is a condition that, when associated with ischemic heart disease and cardiovascular events, can be influenced by genetic variants and determine more severe coronary atherosclerosis. Objectives: To examine the contribution of genetic polymorphisms to the extension and severity of coronary disease in subjects with MS and recent acute coronary syndrome (ACS). Methods: P...

Rare Presentation of Dercum’s Disease in a Child with Abnormalities in Lipoprot...

Electrocardiogram Performance in the Diagnosis of Left Ventricular Hypertrophy ...

Abstract Background: Left ventricular hypertrophy (LVH) is an important risk factor for cardiovascular events, and its detection usually begins with an electrocardiogram (ECG). Objective: To evaluate the impact of complete left bundle branch block (CLBBB) in hypertensive patients in the diagnostic performance of LVH by ECG. Methods: A total of 2,240 hypertensive patients were studied. All of them were submitted...

Effects of Chronic Exercise on Endothelial Progenitor Cells and Microparticles ...

Abstract Background: The effects of chronic exposure to exercise training on vascular biomarkers have been poorly explored. Objective: Our study aimed to compare the amounts of endothelial progenitor cells (EPCs), and endothelial (EMP) and platelet (PMP) microparticles between professional runners and healthy controls. Methods: Twenty-five half-marathon runners and 24 age- and gender-matched healthy controls we...

Diretriz brasileira baseada em evidências sobre prevenção de doenças cardiovasc...

Resumo Fundamentação: desde o primeiro posicionamento da Sociedade Brasileira de Diabetes (SBD) sobre diabetes e prevenção cardiovascular, em 2014,1 importantes estudos têm sido publicados na área de prevenção cardiovascular e tratamento do diabetes,2 os quais contribuíram para a evolução na prevenção primária e secundária nos pacientes com diabetes. Ferramentas de estratificação de risco mais precisas, novos f...

Microparticles as Potential Biomarkers of Cardiovascular Disease

Primary prevention of cardiovascular disease is a choice of great relevance because of its impact on health. Some biomarkers, such as microparticles derived from different cell populations, have been considered useful in the assessment of cardiovascular disease. Microparticles are released by the membrane structures of different cell types upon activation or apoptosis, and are present in the plasma of healthy i...

I Posicionamento Brasileiro sobre Combinação de Fármacos Anti-Hipertensivos

Avaliação da hipertensão arterial resistente pela monitorização residencial da ...

FUNDAMENTO: A monitorização ambulatorial da pressão arterial (MAPA) é considerada o padrão-ouro para a confirmação diagnóstica da hipertensão arterial resistente (HAR). No entanto, a monitorização residencial da pressão arterial (MRPA) tem sido considerada uma opção, pelo seu custo menor e maior conforto. OBJETIVO: Comparar os valores obtidos pela MRPA com os obtidos pela MAPA na identificação de pacientes hipe...
