BACKGROUND Coronary artery bypass graft surgery with cardiopulmonary bypass is a safe, routine procedure. Nevertheless, significant morbidity remains, mostly because of the body's response to the nonphysiological nature of cardiopulmonary bypass. Few data are available on the effects of off-pump coronary artery bypass graft surgery (OPCAB) on cardiac events(More)
BACKGROUND Prior comparisons of costs following CABG and PTCA have demonstrated higher initial costs after CABG but following PTCA, recurrent symptoms and repeat revascularization result in increased late costs and over time their costs equilibrate. The MASS II trial provides an opportunity to compare the costs of CABG and PTCA in addition to a strategy of(More)
There is a very well known correlation between diabetes and cardiovascular disease but many health care professionals are just concerned with glycemic control, ignoring the paramount importance of controlling other risk factors involved in the pathogenesis of serious cardiovascular diseases. This Position Statement from the Brazilian Diabetes Society was(More)
BACKGROUND Renal transplant candidates are at high risk of coronary artery disease (CAD). We sought to develop a new risk score model to determine the pre-test probability of the occurrence of significant CAD in renal transplant candidates. METHODS A total of 1,060 renal transplant candidates underwent a comprehensive cardiovascular risk evaluation.(More)
BACKGROUND The link between endogenous estrogen, coronary artery disease (CAD), and death in postmenopausal women is uncertain. We analyzed the association between death and blood levels of estrone in postmenopausal women with known coronary artery disease (CAD) or with a high-risk factor score for CAD. METHODS 251 postmenopausal women age 50-90 years not(More)
OBJECTIVES To determine the safety of intramyocardial injection of autologous bone marrow cells in patients undergoing surgical myocardial revascularization (CABG) for severe coronary artery disease. INTRODUCTION There is little data available regarding the safety profile of autologous bone marrow cells injected during surgical myocardial(More)
BACKGROUND The investigation of stable coronary artery disease (CAD) and its treatment depend on risk stratification for decision-making on the need for cardiac catheterization and revascularization. OBJECTIVE To analyze the procedures used in the diagnosis and invasive treatment of patients with CAD, at the Brazilian Unified Health System (SUS) in the(More)
OBJECTIVES Since waiting lists for coronary artery bypass graft surgery are common and carry a risk of severe events, the purposes of this study were: (1) to analyse the incidence and temporal distribution of cardiac complications during waiting for elective coronary artery bypass grafting; (2) to identify predictive factors of such complications. METHODS(More)
OBJECTIVE The participation of humans in clinical cardiology trials remains essential, but little is known regarding participant perceptions of such studies. We examined the factors that motivated participation in such studies, as well as those that led to participant frustration. METHODS Patients who had participated in hypertension and coronary arterial(More)
BACKGROUND The incidence of unexplained sudden death (SD) and the factors involved in its occurrence in patients with chronic kidney disease are not well known. METHODS We investigated the incidence and the role of co-morbidities in unexplained SD in 1139 haemodialysis patients on the renal transplant waiting list. RESULTS Forty-four patients died from(More)
