Trimetazidine has been shown to have an antianginal effect, increasing exercise capability without producing any significant change of heart rate or systolic blood pressure. The aim of this study was to compare trimetazidine efficiency to that of another classical antianginal drug. A double-blind crossover trimetazidine versus nifedipine trial was carried(More)
OBJECTIVE Coronary artery disease (CAD) is a leading cause of mortality and morbidity in diabetic patients; therefore, their risk stratification is a relevant issue. Because exercise tolerance is frequently impaired in these patients, pharmacological stress echocardiography (SE) has been suggested as a valuable alternative. Our aim was to evaluate the(More)
One hundred twenty-five patients (60 +/- 10 years old, 60 women) with known (35, previous myocardial infarction) or suspected (90) coronary artery disease (CAD) and no more than 50% coronary stenoses underwent pharmacologic (48 dipyridamole and 77 dobutamine) stress echocardiography (SE) and prospective follow-up (36 +/- 22 months) for cardiac death,(More)
BACKGROUND AND HYPOTHESIS The prognostic value of exercise technetium 99m sestamibi single-photon emission computed tomography (SPECT) imaging in patients with previous bypass surgery is unknown. The aim of our study was to assess the prognostic information obtained with exercise scintigraphy performed for routine follow-up or reappearance of symptoms. (More)
OBJECTIVE To test the hypothesis that chelation therapy with deferoxamine would prevent alterations in left ventricular systolic and diastolic function due to transfusional iron overload in patients with thalassemia major. DESIGN A consecutive series of patients receiving chronic transfusional and chelation therapy were studied by two-dimensional and(More)
BACKGROUND Through contemporary literature, the optimal strategy to manage coronary chronic total occlusions (CTOs) remains under debate. OBJECTIVES The aim of the Italian Registry of Chronic Total Occlusions (IRCTO) was to provide data on prevalence, characteristics, and outcome of CTO patients according to the management strategy. METHODS The IRCTO is(More)
UNLABELLED Cardiac PET studies in patients with left bundle branch block (LBBB) are few, and the results are conflicting. In particular, even if a reduced uptake of FDG is reported, confirmation in a large group of patients and exact understanding of the underlying cause are lacking. METHODS We selected 29 consecutive patients who had complete LBBB and no(More)
Arteriotomy closure devices used to obtain hemostasis at the end of cardiac catheterization represent a valid alternative to manual compression. We are the first to report on a series of 60 patients in whom a novel system was used, Star-Close, which obtains vessel closure by deployment of a clip at the puncture site. Subsequent early (2 hours) mobilization(More)
OBJECTIVES The purpose of this study was to assess the determinants of mortality in a large group of patients with ischemic cardiomyopathy who are treated medically and the impact of the extent of viable tissue on prognosis. BACKGROUND Whether the presence of viability drives mortality in patients with ischemic cardiomyopathy who are treated medically and(More)
The present study evaluated the association among sonographic characteristics of carotid plaques, angiographic morphology of coronary lesions, and outcomes of patients who had acute coronary syndromes. In treatment-stratified Cox's proportional hazards regression analysis, hard carotid plaques and coronary lesions of complex morphology were found to be(More)
