13. 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 with severe obstructive CAD and good (n = 70) or poor (n =

14. Relationship between Obesity and Coronary Artery Disease Defined by Coronary Computed Tomography Angiography
Abstract Background: Although associated with traditional cardiovascular risk factors, it is unclear whether obesity alone is associated with coronary artery disease (CAD). Objective: To investigate the role of obesity as a risk factor for CAD, defined by coronary computed tomography angiography (CCTA). Methods: This study retrospectively included 1,814 p

15. Myocardial Perfusion by Coronary Computed Tomography in the Evaluation of Myocardial Ischemia: Simultaneous Stress Protocol with SPECT
Resumo Fundamento: A avaliação funcional para descartar a isquemia miocárdica utilizando a angiotomografia computadorizada (angio-TC) de coronárias é de extrema importância e dados na população brasileira ainda são escassos. Objetivo: Avaliar o desempenho diagnóstico da perfusão miocárdica pela angio-TC de coronárias na detecção de doença a

17. Impact of Complications of Myocardial Revascularization Surgery on Expenses During Hospital Stay
Abstract Background: Coronary artery bypass grafting (CABG) is an important treatment option for obstructive coronary artery disease, but it represents a high expense for paying sources. The complications of CABG impose an additional expense to the procedure that is not yet clearly established. Objective: To determine the economic impact of postoperative c

19. Circulating levels of adiponectin and extent of coronary artery disease in patients undergoing elective coronary angiography
Adiponectin (APN), an adipose tissue-released adipokine with demonstrated anti-inflammatory and anti-atherogenic properties, is encoded by a gene whose polymorphisms are associated with presence of coronary artery disease (CAD). Serum APN levels are inversely related with presence and complexity of CAD. Within this context, we sought to compare levels of tot

20. Lipoprotein(a) as a predictor of poor collateral circulation in patients with chronic stable coronary heart disease
As a mechanism compensating for obstructive coronary artery disease, coronary collateral circulation (CCC) has attracted cardiologists for a long time to explore its potential impact. In the present study, Chinese patients suffering from ≥95% coronary stenosis, as diagnosed by angiography, have been investigated for the correlation between CCC and lipoprot

21. Epicardial adipose tissue and pericoronary fat thickness measured with 64-multidetector computed tomography: potential predictors of the severity of coronary artery disease
OBJECTIVE:The aim of the present study was to investigate the relationship between pericoronary fat and the severity and extent of atherosclerosis, quantified using 64-multidetector computed tomography, in patients with suspected coronary artery disease.METHODS:The study population consisted of 131 patients who were clinically referred for noninvasive multis

22. Validação de sistema portátil de monitorização respiratória para o diagnóstico de apneia obstrutiva do sono em pacientes com doença arterial coronariana / Validation of portable respiratory monitoring system for the diagnosis of obstructive sleep apnea in patients with coronary artery disease
Introduction: Obstructive sleep apnea (OSA) is characterized by repeated episodes of partial or complete collapse of the upper airway during sleep, resulting in respiratory events characterized by hypopnea or apnea, respectively. Respiratory events may result in sleep fragmentation, hypoxemia and recurrent generation of negative intrathoracic pressure. All t

23. The characteristics of stress cardiomyopathy in an ethnically heterogeneous population
OBJECTIVES: Stress cardiomyopathy is a cardiac syndrome that is characterized by transient left ventricular systolic dysfunction in the absence of obstructive coronary artery disease. Its epidemiology has been described in homogeneous Asian, Caucasian and Black populations, but its characteristics in heterogeneous populations are poorly understood. Our aim w

24. Estudo da perfusão miocárdica e reserva coronariana pela ecocardiografia sob estresse com perfusão em tempo real em pacientes com diabetes melito descompensado e após tratamento / Myocardial perfusion study and coronary flow reserve by real-time utilizing myocardial contrast echocardiography in decompensated diabetic patients after treatment
Background: Diabetes mellitus (DM) is associated with alterations in coronary flow reserve on microvascular circulation. Real-time myocardial contrast echocardiography has proven to be a useful method for non-invasive evaluation of microvascular alterations. The objective of this study was to assess whether the control of diabetes would influence the values
