Abstract Background Ischemic Stroke (IS) and Coronary Artery Disease (CAD) frequently coexist and share atherosclerotic disease risk factors. According to the American Heart Association, IS subtypes may be considered CAD risk equivalents, but the evidence for non-atherosclerotic IS is uncertain. Additionally, the Coronary Calcium Score (CCS) is an accurate marker to address CAD risk; however, CCS distribution between IS subtypes is not well characterized. Objectives To compare the CCS between atherosclerotic and non-atherosclerotic IS groups; and to determine which covariates […]

Abstract Background In Chagas’ disease endemic regions, there has been for many years a recurrent empirical observation that coronary artery disease (CAD) is uncommon in patients with Chagas’ disease. Previous pathological and invasive coronary angiography studies led to controversial results. Objective We sought to investigate whether CAD is less prevalent and less severe in patients with chronic Chagas’ disease when compared with a matched population with a similar CAD risk profile. Methods A total of 86 participants, 43 consecutive patients […]

Abstract Background: Women seem to be more susceptible to psychosocial stress than men, and stress is associated with worse outcomes after acute myocardial infarction (AMI). Objectives: To investigate whether the female gender is an independent predictor of risk for stress and to compare stress levels between women and men after AMI. Methods: Cross-sectional study of a case series. Patients aged 18 to 65 years who were treated for AMI at the study facility between January 2017 and June 2018 were […]

Dear Editor, We read with interest the short editorial written by authors Chamié and Abzaid regarding the paper “Evaluation of Myocardial Ischemia with iFR (instantaneous wave-free ratio) in the catheterization laboratory: a pilot study”. The short editorial clearly translates to us the historical evolution reasoning that we must follow when interpreting coronary physiology studies in therapeutic decision-making. Although medicine is full of binary situations for resolution, such as the presence or absence of fever by the thermometer, it is very […]

Abstract Background TIMI flow grade and corrected TIMI frame count (CTFC) are widely used methods to evaluate angiographic coronary blood flow. Measurement of coronary blood flow (CBF) on standard coronary angiography (CAG) has aroused great interest recently, trying to combine the CTFC concept with new methods for post-angioplasty and for cardiac syndrome X assessment. Additionally, coronary slow flow it is now considered a major criterion for microvascular angina. Objective Explore a new approach of quantitative angiographic measurement of CBF based […]

Abstract Background Cardiovascular disease is the leading cause of mortality in the world. Parietal calcifications of the arteries may be visualized and quantified at initial and subclinical states by computed tomography (CT), and expressed as calcium score (CS). It is possible to estimate the prognosis of future cardiovascular events using this score. Objectives To correlate the detection and quantification of the CS obtained by chest CT with that obtained by electrocardiography (ECG)-synchronized cardiac computed tomography (the gold-standard). Method Cross-sectional, descriptive […]
