Abstract Background Acute coronary syndrome (ACS) is one of the leading causes of mortality worldwide. Knowing the predisposing factors is essential for preventing it. Objectives To describe the etiological and epidemiological characteristics of the population with ACS admitted to an emergency room in the State of São Paulo. Methods The prospective cohort study, based on electronic medical records from a public cardiology institute located in the state of São Paulo, Brazil, describes 5,580 patients hospitalized with ACS between August 2018 […]

The ORBITA trial Although the above-mentioned studies have demonstrated some improvement in angina after myocardial revascularization, one of their major limitations is the open nature and a possible placebo effect. In this regard, the ORBITA study showed no benefit of PCI versus a placebo procedure on the primary end-point of an increase in exercise time. ORBITA was a well conducted study that demonstrated the possibility of a placebo component and lack of symptom improvement by PCI. However, several limitations could […]

ABOUT THESE STATISTICS The publication Cardiovascular Statistics – Brazil aims to provide an annual compilation of data and research on the epidemiology of CVDs in Brazil. The report integrates official statistics from the Brazilian Ministry of Health and other governmental entities alongside data from the GBD project, coordinated by the IHME at the University of Washington. Additionally, it incorporates data derived from various sources and scientific studies, including cohorts and registries, that relate to CVDs and their associated risk factors. […]

Case description A 57-year-old Caucasian male patient with a past medical history of hypertension and pulmonary emphysema presented to the Cardiology outpatient clinic with exertional dyspnea, peripheral edema, orthopnea, and new-onset atrial fibrillation, with a III/VI continuous murmur, raising the possibility of an intrathoracic arteriovenous communication. A transthoracic echocardiogram revealed a dilated left ventricle with mildly reduced global systolic function (ejection fraction of 44%), biatrial enlargement, and mild pericardial effusion. Notably, this study showed multiple ‘rosary-like’ folds (, , -) […]

To the Editor, We read with great interest the article: “Cost-Effectiveness of Using the Coronary Calcium Score to Guide Therapeutic Decisions in Primary Prevention in the Brazilian Population” The study aimed to evaluate the cost-effectiveness of using the calcium score in therapeutic guidance for primary cardiovascular prevention. The analysis was based on population data from the “ Multi-Ethnic Study of Atherosclerosis (MESA),” a cohort of 6,814 participants from different study centers in the United States. The inferences made by the […]

Abstract Background Oncostatin M (OSM) is a pleiotropic cytokine which, after arterial injury, has proven to be to be rapidly expressed. Objectives To correlate the serum levels of OSM, soluble OSM receptor (sOSMR), and soluble fraction of glycoprotein 130 (sgp130) in patients with coronary artery disease (CAD) with clinical parameters. Methods Levels of sOSMR and sgp130 were evaluated by ELISA and OSM by Western Blot, in patients with CCS (n=100), patients with ACS (n=70), and 64 control volunteers without clinical […]

About these statistics This is the 2021 edition of the Cardiovascular Statistics – Brazil , a multi-institutional effort to periodically provide updated information on the epidemiology of heart diseases and stroke in Brazil. The report incorporates official statistics provided by the Brazilian Ministry of Health and other government agencies, by the GBD project led by the IHME of the University of Washington, as well as data generated by other sources and scientific studies, such as cohorts and registries, on CVDs […]

Abstract Background The Brazilian public health system does not include computed tomography angiography (CTA). Objective Rank, according to the Brazilian public health system, the cost-effectiveness of different strategies for the diagnosis of coronary artery disease (CAD), combining exercise tests (ET), myocardial scintigraphy (MS), stress echocardiography (SE), and CTA in a hypothetical intermediate pre-test probability cohort of patients. Methods This study implemented a cost-effectiveness analysis through a decision tree. The incremental cost-effectiveness ratio (ICER) and net benefit were analyzed by adopting […]
