Lipoprotein lipase is the rate-limiting enzyme in the lipolysis of plasma triglyceride-rich lipoproteins. We studied six variants (T-93G, D9N, N291S, PvuII, HindIII and S447X) in the lipoprotein lipase (LPL) gene in 309 non-diabetic patients with angiographically assessed coronary artery disease and in 197 controls in a southern Brazilian population of(More)
Hepatic lipase (HL) is a glycoprotein that plays a major role in remodeling high-density lipoprotein (HDL). The effect of the -250G/A promoter polymorphism on coronary artery disease (CAD) and lipid levels was studied in 231 male CAD patients and in a population-based sample of men and women (n = 514). A sample of 140 men was chosen among those included in(More)
Horseshoe kidney is a rare congenital anomaly that may cause various technical problems during conventional repairs of abdominal aortic aneurysms. We report the case of a 68-year-old woman with a horseshoe kidney, symptomatic abdominal aortic aneurysm and mild renal failure. The patient underwent endovascular repair using a bifurcated endoprosthesis. The(More)
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)
INTRODUCTION The association between erectile dysfunction (ED) and coronary artery disease (CAD) has been described in various settings, but it is unclear if there is an independent interaction with age. AIM To investigate the interaction of age in the association between ED and CAD. METHODS This case-control study was conducted among 242 patients(More)
Endothelin (ET)-1 levels were analyzed in patients who underwent elective coronary stenting. There was a significant increase in systemic ET-1 levels immediately after the procedure, which is probably a marker of endothelial dysfunction that is associated with arterial injury. However, there was no association between ET-1 levels and in-stent restenosis in(More)
In this study, we examined the insertion/deletion (Ins/Del) and XbaI polymorphisms of the apolipoprotein B (APOB) gene and the -36delG polymorphism in the sterol regulatory element binding protein-1a (SREBP-1a) gene in 298 patients with non-diabetic angiographically assessed coronary artery disease (CAD), and 188 healthy controls, from a Brazilian(More)
Situs inversus totalis is a rare congenital anomaly. We report a case of a 78-year-old woman with this condition and ischemic coronary artery disease who underwent myocardial revascularization. The cardiac catheterism showed severe proximal stenosis with aneurysms in the anterior interventricular branch, diagonal artery, and right coronary artery. The(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)
