Enfermedad coronaria en el paciente portador del virus de la inmunodeficiencia humana

Rev. chil. cardiol; 40 (2), 2021
RESUMEN: Las enfermedades cardiovasculares, particularmente la enfermedad coronaria (EC), resultan de especial interés y preocupación en pacientes portadores del virus de la inmunodeficiencia humana (VIH). La ateromatosis acelerada como causa del aumento de prevalencia de enfermedad coronaria ha sido r...

Evaluación no invasiva de la significancia funcional de las lesiones coronarias mediante quantitative flow ratio (QFR): validación con reserva de flujo fraccional (FFR)

Rev. chil. cardiol; 40 (2), 2021
RESUMEN: Introducción: La evaluación de lesiones coronarias mediante Reserva de Flujo Fraccional (FFR), es de elección para determinar su significancia funcional en el laboratorio de hemodinamia. La razón de flujo cuantitativo (Quantitative Flow Ratio, QFR) es una nueva técnica no invasiva para la e...

QT Interval Dispersion Behavior in Patients With and Without Obstructive Coronary Artery Disease Undergoing Exercise Test

Abstract Background: Stress test is used to detect coronary artery disease (CAD). The QTc interval dispersion (dQTc) is an electrocardiographic index of ventricular repolarization heterogeneity. Some researchers have linked transient myocardial ischemia induced by physical exertion with increased hetero...

Visceral fat index: a novel predictor for coronary collateral circulation

ABSTRACT Objective This study was designed to investigate the role of visceral adiposity along with other clinical parameters in predicting poor coronary collateral circulation (CCC) among patients with severe obstructive coronary artery disease (CAD). Subjects and methods A total of 135 patients wit...

Association between Hemogram Parameters and Coronary Collateral Development in Subjects with Non-ST-Elevation Myocardial Infarction

SUMMARY OBJECTIVE Coronary collateral development (CCD) predicts the severity of coronary heart disease. Hemogram parameters, such as mean platelet volume (MPV), eosinophil, red cell distribution width, and platelet distribution width (PDW), are supposed novel inflammatory markers. We aimed to compare ...

Influence of the hydration on autonomic modulation and cardiorespiratory parameters of coronary heart disease patients submitted to a cardiovascular rehabilitation session: crossover clinical trial protocol

Motriz (Online); 26 (1), 2020
Abstract Aims: The influence of fluid replacement, realized during and after the exercise on individuals with coronary artery disease (CAD) remains poorly understood. To investigate the influence of hydration on cardiac autonomic modulation, cardiorespiratory parameters and perceived exertion and discom...

Análise do encurtamento pós-sistólico, do strain Miocárdico e do fluxo arterial na avaliação de Isquemia Miocárdica durante o Ecocardiograma sob Estresse

Myocardial Perfusion by Coronary Computed Tomography in the Evaluation of Myocardial Ischemia: Simultaneous Stress Protocol with SPECT

Arq. bras. cardiol; 113 (6), 2019
Abstract Background: Functional assessment to rule out myocardial ischemia using coronary computed tomography angiography (CCTA) is extremely important and data on the Brazilian population are still limited. Objective: To assess the diagnostic performance of myocardial perfusion by CCTA in the detectio...

Physical Activity Levels in Peripheral Artery Disease Patients

Arq. bras. cardiol; 113 (3), 2019
Abstract Background: Increases in daily physical activity levels is recommended for patients with peripheral artery disease (PAD). However, despite this recommendation, little is known about the physical activity patterns of PAD patients. Objective: To describe the physical activity patterns of patient...
