BACKGROUND Serum cystatin C (s-CC), an endogenous marker of kidney function, has also been proposed as a cardiovascular risk marker. However, it is unknown whether it is a direct marker of atherosclerosis, independently of kidney function. OBJECTIVE The aim of this study was to correlate s-CC with two surrogate markers of subclinical atherosclerosis. (More)
BACKGROUND Left ventricular hypertrophy (LVH) is an independent predictor of cardiovascular risk, and its characterization and prevalence in chronic renal disease (CRD) should be further studied. OBJECTIVE To establish the diagnosis of LVH in patients with stage-5 CRD using six different electrocardiographic criteria, and to correlate them with left(More)
OBJECTIVE To assess the safety and efficacy of unsupervised rehabilitation (USR) in the long run in low-risk patients with coronary artery disease. METHODS We carried out a retrospective study with 30 patients divided into: group I (GI) - 15 patients from private clinics undergoing unsupervised rehabilitation; group II (GII) - control group, 15 patients(More)
Coronary artery disease has a heterogeneous range of clinical presentations that varies from asymptomatic patients with multivessel disease to patients with one-vessel disease with acute myocardial infarction (AMI) and even sudden death. Other patients have stable angina that has evolved over many years, even decades, without progressing to unstable angina(More)
BACKGROUND Predischarge exercise testing early after myocardial infarction is useful for risk stratification, exercise prescription, and assessment of prognosis and treatment. OBJECTIVE The objective of this study was to compare the findings of exercise testing early after myocardial infarction with those of echocardiography, electrocardiographic(More)
BACKGROUND In patients with type 1 diabetes mellitus, atherosclerosis occurs earlier in life and coronary artery disease (CAD) constitutes the major cause of death. OBJECTIVE Evaluate the prevalence and anatomic characteristics of coronary artery disease (CAD) in type 1 diabetic patients with chronic renal failure undergoing hemodialysis. METHODS This(More)
Coronary angiography can lead to different kinds of complications. Catheter-induced coronary dissection is one of the most feared of them. It is uncommonly reported and may result in ischemic events ranging from angina to death. We report a case of a woman admitted to the hospital due to progressive effort angina who had a complication during percutaneous(More)
As células-tronco mesenquimais representam uma rara subpopulação das células-tronco da medula óssea (< 0,01% das células mononucleares da medula óssea) com capacidade de expansão mitótica in vitro. Em decorrência da facilidade em se dividir e proliferar, concluiu-se que as células-tronco mesenquimais seriam as células responsáveis pela manutenção e(More)
A 38-year-old man with acute myocardial infarction in the lower wall affecting the right ventricle underwent thrombolytic treatment with streptokinase. Approximately 2 hours after the thrombolytic treatment started, he presented with signs of coronary reocclusion. He underwent emergency cineangiocoronariography that revealed that his right coronary artery(More)
A meta-analysis of clinical studies of patients with cardiovascular disease demonstrated that the use of aspirin was associated with a 22% decrease in death rates and relevant ischemic vascular events. However, clinical studies demonstrated that patients that regularly took aspirin presented recurrence of cardiovascular events. Such observation led to the(More)
