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.

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.

Background/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.

Introduction: The underlying cause of death is the single diagnosis to which the cause of death is attributed. Other diagnostic codes written in the death certificate are the multiple causes. The study of the multiple causes allows the identification of the diseases present in the death.

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 (CVD) are the leading cause of death in Brazil.

Objective: To estimate total CVD, cerebrovascular disease (CBVD), and ischemic heart disease (IHD) mortality rates in adults in the counties of the state of Rio de Janeiro (SRJ), from 1979 to 2010.

Methods: The counties of the SRJ were analysed according to their denominations stablished by the geopolitical structure of 1950, Each new county that have since been created, splitting from their original county, was grouped according to their former origin.

Method: Were analysed in-hospital administrative database coming from the Public Health System of Rio de Janeiro (SUS-RJ) from 2006 through 2010 and the Public Registers of death of Rio de Janeiro (SIM-RJ) from 2006 through 2013. Both groups of information had linkaged using the Stata program of statistics.

Introduction: Ischemic peripheral arterial disease is a form of presentation of systemic atherosclerosis and can be treated by angioplasty or open vascular surgery Objective: To find in-hospital lethality after revascularization according to sex, age, procedures and hospitalization conditions.

Method: The data comes from authorizations to hospitalize from The State of Rio De Janeiro´s Public Healthcare System from the years 2006/10. We performed a search using the International Code of Diseases tenth revision (ICD-10) to identify codes of revascularization by angioplasty or open vascular surgery.

Background: End-stage kidney disease patients continue to have markedly increased cardiovascular disease morbidity and mortality. Analysis of genetic factors connected with the renin-angiotensin system that influences the survival of the patients with end-stage kidney disease supports the ongoing search for improved outcomes.

Objective: To assess survival and its association with the polymorphism of renin-angiotensin system genes: angiotensin I-converting enzyme insertion/deletion and angiotensinogen M235T in patients undergoing hemodialysis.

Background: The standardization of images used in Medicine in 1993 was performed using the DICOM (Digital Imaging and Communications in Medicine) standard. Several tests use this standard and it is increasingly necessary to design software applications capable of handling this type of image; however, these software applications are not usually free and open-source, and this fact hinders their adjustment to most diverse interests.

Objective: To develop and validate a free and open-source software application capable of handling DICOM coronary computed tomography angiography images.

Objective: To evaluate associations between post-operative complications in patients who survive surgery and in-hospital deaths and lengths of hospital stays of patients who undergo coronary artery bypass graft surgery

Methods: Patients who underwent coronary artery bypass graft surgery and survived the operating theater were randomly selected. Information on complications and hospital lengths of stay until hospital discharge or death were retrospectively collected based on medical records and declarations of death. These aspects were estimated according to the presence of complications, frequency of complications, mortality, relative risk and attributable population risk.
