OBJECTIVE To verify if endothelial function is impaired in pre-menopausal women with systemic lupus erythematosus (SLE) and whether endothelial dysfunction is related to disease duration, cumulative prednisone dose, antimalarial use, anticardiolipin antibody (aCL), hypertension, Raynaud's phenomenon, disease activity score, and vasculitis. METHODS Using(More)
BACKGROUND Radiographic contrast media exposition can cause acute renal function impairment. There is limited and conflicting evidence that hydration with sodium bicarbonate prevents contrast-induced nephropathy (CIN) in patients undergoing cardiac catheterization. OBJECTIVE The present study was aimed at determining whether sodium bicarbonate is superior(More)
BACKGROUND Diabetic cardiomyopathy is a well-defined complication of diabetes that occurs in the absence of ischemic, vascular, and hypertensive disease. HYPOTHESIS The study was undertaken to test the relationship among autonomic neuropathy (AN), 24-h blood pressure (BP) profile, and left ventricular function. METHODS Nineteen type-1 diabetic patients(More)
Doppler derived systolic pressure gradients have become widely applied as noninvasively obtained estimates of the severity of aortic valvar stenosis. There is little correlation, however, between the Doppler derived peak instantaneous gradient and the peak-to-peak gradient obtained at catheterisation, the latter being the most applied variable to determine(More)
OBJECTIVES We assessed the endothelial-dependent vasomotor function in nonrestenotic coronary arteries more than six months following stent implantation, balloon angioplasty (BA), and directional atherectomy (DCA). BACKGROUND Catheter-based coronary interventions are associated with extensive arterial injury. Endothelial function has been shown to remain(More)
Seven female patients (age 27 to 53 yr) with significant mitral stenosis performed continuous, incremental, maximal treadmill exercise tests the day before and within 3-5 days after catheter-balloon valvuloplasty. Mitral valve area determined by the echo-Doppler method increased from 0.9 +/- 0.3 cm2 to 1.9 +/- 0.7 cm2 (p < 0.02). Mean left atrial pressure(More)
BACKGROUND We aimed to determine the incidence, predictors, clinical characteristics, management, and outcomes of infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS This multicenter registry included 53 patients (mean age, 79±8 years; men, 57%) who suffered IE after TAVI of 7944 patients after a mean(More)
OBJECTIVES We tested two novel drug-eluting stents (DES), covered with a biodegradable-polymer carrier and releasing paclitaxel or sirolimus, which were compared against a bare metal stent (primary objective). The DES differed by the drug, but were identical otherwise, allowing to compare the anti-restenosis effects of sirolimus versus paclitaxel (secondary(More)
