BACKGROUND A number of epidemiological studies have described a positive relationship between serum ferritin levels and coronary heart disease. In this prospective study, we evaluated the association between serum ferritin levels and the angiographic extent of coronary atherosclerosis. METHOD We studied 307 consecutive patients (60.9% male, age(More)
Metabolic syndrome (MS) identifies cardiovascular risk; however, there is little information regarding the evolution of patients with MS after stent implantation. The aim of this single-center study is to evaluate the possible association between MS and clinical restenosis, after adjustment for highsensitivity C-reactive protein (hs-CRP) and angiographic(More)

OBJECTIVE To assess the association between cardiovascular risk factors and acute myocardial infarction as the first manifestation of ischemic heart disease, correlating them with coronary angiographic findings. METHODS We carried out a cross-sectional study of 104 patients with previous acute myocardial infarction, who were divided into 2 groups(More)
PURPOSE To compare the severity of the coronary heart disease and the presence of coronary risk factors between angina and myocardial infarction (MI) patients. METHODS We studied 62 patients with MI and 129 with angina through coronary angiography to evaluate occlusion (lesion of 99% or 100%), extent (with a score of 0-5 derived by the number of vessels(More)
Considering that the world's population average age is increasing and the proportions of those over the age of 80, the fastest growing population worldwide, new approaches to health care and treatment will be necessary. Due to the development of new drugs and by means of transluminal coronary angioplasty or coronary artery bypass graft, many elderly(More)
PURPOSE To identify a possible relationship of the extent of coronary artery disease, with risk factors for coronary artery disease and the retinal arteriolar changes (evaluated by fundoscopic examination). METHODS We studied 96 patients (66 males), 36 to 72 years of age. All patients were studied by selective cinecoronaryarteriography, fundoscopic(More)
In renal transplant patients dietary therapy alone does not always provide satisfactory results to control hyperlipidemia. To assess the effectiveness of diet, 151 renal transplant patients were selected for a prospective clinical study using pre- and posttest groups. During 8 weeks these patients received a diet with 25% energy intake from lipids, less(More)
