OBJECTIVE To determine the prevalence of micro- and macroalbuminuria in NIDDM and their relationship with some known and putative risk factors. RESEARCH DESIGN AND METHODS Out of a population-based cohort of 1,967 NIDDM subjects, 1,574 were investigated (80%). Albumin excretion rate (AER) was evaluated on an overnight urine collection, and plasma and(More)
BACKGROUND Percutaneous aortic valve replacement (PAVR) may be an alternative therapy for patients with severe aortic stenosis who are denied valve surgery because of age and comorbidity. Data are few regarding the incidence of early conduction disorders (CD) after PAVR. We examined the incidence and characteristics of CD in the immediate postoperative(More)
BACKGROUND Transcatheter aortic valve implantation (TAVI) carries higher risk of post-procedural adverse events than conventional percutaneous cardiovascular interventions. We report our experience about postoperative management protocol adopted in our Division. METHODS One hundred and ten patients underwent TAVI and 108 were transferred to the cardiac(More)
Secondary heart failure induced by organ siderosis is the main cause of death in patients affected by thalassemia major. At present it cannot be predicted whether heart siderosis is correlated with iron overload and little is known about the real cardiac histological pattern of post transfusional hemochromatosis in patients with thalassemia major and(More)
BACKGROUND Warfarin, despite its known limitations, is the reference standard treatment for patients with AF and risk factors for stroke. We performed a meta-analysis of phase III trials that compare novel oral anticoagulants (NOACs) with warfarin to determine whether they improve clinical outcomes of patients with non-valvular atrial fibrillation (AF).

Studies specifically designed to assess clopidogrel response in the elderly as well as treatment alternatives to improve platelet inhibition in this high-risk population are lacking. This study aimed to define pharmacodynamic (PD) profiles, including high platelet reactivity (HPR) rates, among elderly patients on maintenance clopidogrel therapy and to(More)
BACKGROUND Cardiac resynchronization therapy (CRT) is effective in selected patients with heart failure (HF). Nevertheless, the nonresponder rate remains high. The low-dose dobutamine stress-echo (DSE) test detects the presence of left ventricular (LV) contractile reserve (LVCR) in HF patients of any etiology and may be useful in predicting response to(More)
Conduction disorders and permanent pacemaker (PPM) implantation are common complications in patients undergoing transcatheter aortic valve implantation (TAVI). Previous studies, evaluating small populations, have identified several different predictors of PPM implantation after TAVI. The aim of this study was to assess the incidence rate of conduction(More)
BACKGROUND The assessment of defibrillation efficacy using a safety margin of 10 J has long been the standard of care for insertion of implantable cardioverter-defibrillator (ICD), but physicians are concerned about complications related to induction test. Therefore, the need for testing has been recently questioned. The aim of our study was to assess the(More)
Cardiac resynchronization therapy (CRT) is an effective methodology indicated in selected heart failure patients. Identifying responders to the therapy is still challenging. Most studies report that at least 30% of the patients are nonresponders. Baseline characteristics of the Low-Dose Dobutamine Stress Echocardiography to Predict Cardiac Resynchronization(More)
