The prognostic value of atrial thrombi (AT) among elective patients with atrial fibrillation (AF) referred for a rhythm control strategy is unclear. In this study, clinical variables were correlated with the presence of AT and long term survival among 205 patients submitted to transesophageal echocardiography before elective AF cardioversion or ablation. Atrial thrombi were present in 7.

The aim of this study was to compare the in-hospital complication rates and mortality in addition to long-term survival following elective PCI in two reference public and private cardiology hospitals in Rio de Janeiro, Brazil.
Methods: From January 1st 2013 to December 31st 2014, a total of 440 procedures were identified in both hospitals (public: 328 vs.
Medium-term outcomes of 78,808 patients after heart valve surgery in a middle-income country: a nationwide population-based study.
BMC Cardiovasc Disord
December 2017
Background: Heart valve surgery outcomes are unknown in middle-income countries and thus cannot be used in health system decision making processes. This study estimated in-hospital mortality and medium and long-term survival.
Methods: This was a retrospective study of 78,806 patients who underwent heart valve surgery between 2001 and 2007 in Brazil.
Troponin elevation after coronary angioplasty is a prognostic marker associated with significant morbidity and mortality, although its prevalence varies according to clinical and procedural characteristics. We analyzed the frequency of post-procedural enzyme elevation among 112 elective interventions between 2013 and 2014 in a private hospital in Brazil. Troponin increase was observed in 62.
View Article and Find Full Text PDFBackground/purpose: Although troponin I (TnI) elevation and myocardial injury after percutaneous coronary interventions (PCI) are frequent findings, their prognoses remain controversial. We aimed to determine the association between any or ≥5 times TnI elevation after elective PCI and subsequent one year mortality rates and long term survival.
Methods: Consecutive patients admitted for elective PCI between January 2013 and December 2014 were retrospectively analyzed by chart review in two hospitals in Rio de Janeiro.
Background: Although there is strong evidence of the benefits of antihypertensive treatment, the high prevalence of this important cardiovascular risk factor and its complications, as well as the low control rates of hypertension observed in many studies justify the investigation of these relationships in population studies. The objective was to investigate the ratio of cardiovascular disease mortality between hypertensives (non-treated, controlled and uncontrolled) and non-hypertensives in a cohort of a population sample of adults living in Ilha do Governador, Rio de Janeiro state, Brazil, who were classified in a survey conducted in 1991 and 1992 and whose death certificates were sought 19 years later.
Methods: A cohort study was performed on probabilistic linkage between data from an epidemiological study of hypertension performed in Ilha do Governador, in Rio de Janeiro, Brazil (1991 to 1992) and data from the Mortality Information System of Rio de Janeiro (1991 to 2009).
Background: Cardiovascular diseases are the major cause of death in Brazil.
Objective: To correlate cardiovascular mortality rates in the states of Rio de Janeiro, São Paulo and Rio Grande do Sul, and in their capitals, between 1980 and 2008, with socioeconomic indicators collected from 1949 onwards.
Methods: Population and death data were obtained from the Brazilian Unified Health System databank (Datasus).
Objective: To compare trends in mortality rates from cardiovascular diseases (CVD), ischemic heart diseases (IHD) and cerebrovascular diseases (CBVD) in the States of Rio de Janeiro (RJ), São Paulo (SP) and Rio Grande do Sul (RS) and respective capitals from 1980 to 1999.
Methods: Data regarding CVD deaths were obtained from Datasus, and those regarding populations were obtained from IBGE. Crude and sex and age-adjusted mortality rates were calculated using the direct method (standard population: State of Rio de Janeiro's population twenty years of age or older in 2000).
Objective: To determine the prevalence of risk factors for cardiovascular diseases in employees of the research center at Petrobras.
Methods: In a cross-sectional study, employees of the research center at Petrobras were assessed clinically and by laboratory testing from March 2000 and February 2001. Those who did not attend the periodical annual medical examination of 2000 were excluded from the study.
Objective: To study the distribution and interrelationship among constitutional and biochemical variables with blood pressure (BP) in an population of Yanomami indians. To compare these findings with those of other populations.
Methods: The Yanomami indians were part of the INTERSALT, a study comprising 10,079 males and females, aged from 20 to 59 years, belonging to 52 populations in 32 countries in Africa, the Americas, Asia, and Europe.
Objective: The present study aims to evaluate the environmental role in the distribution of hypertension, obesity, and smoking and spousal concordance for the presence/absence of these 3 cardiovascular risk factors.
Methods: A cross-sectional study was conducted in a community in Rio de Janeiro, Brazil. The households were randomly selected.
