The discovery tha carnitine takes an active part in the transportation of long-chain acyl residues across the inner mitochondrial membrane dates back to 1958. It has been shown experimentally tha a reduction in myocardial carnitine content takes place after 15-30 min of ischemia. L-carnitine was administered orally in doses of 3 g/day for 30 days to 16(More)
BACKGROUND Heart failure is one of the main causes of hospitalization in Italy. In some industrialized countries since the second half of 1990s a halt in the grow rate of hospitalization for this pathology has been observed, and in some cases a reversal. The aim of this study was to evaluate the trend of hospitalization for heart failure in Italy in the(More)
Radiation induced heart disease, with its clinical manifestations, is becoming a growing problem. Its prevalence is increasing, keeping pace with the increased survival of many malignancies. The majority of patients with radiation induced heart disease is constituted by Hodgkin's disease survivors, followed by non Hodgkin's disease, esophageal carcinoma,(More)
BACKGROUND The independent prognostic impact of diabetes mellitus (DM) and prediabetes mellitus (pre-DM) on survival outcomes in patients with chronic heart failure has been investigated in observational registries and randomized, clinical trials, but the results have been often inconclusive or conflicting. We examined the independent prognostic impact of(More)
AIMS To investigate whether myocardial ischaemia elicitable during pharmacological stress echocardiography portends different prognosis in men and women. METHODS AND RESULTS The study group was made by 1733 patients (941 men, 792 women) who underwent dipyridamole (n=1008) or dobutamine (n=725) stress echo for evaluation of known or suspected coronary(More)
BACKGROUND Preoperative screening for coronary artery disease is recommended in high-risk renal transplant candidates. Aim of this study was to prospectively assess the value of a comprehensive risk stratification strategy including clinical, resting echo, and dipyridamole stress echo findings before renal transplantation. METHODS The study group(More)
AIMS The aims of this study were to assess the safety, feasibility and prognostic value of dipyridamole-atropine stress echo in patients with medically stabilized unstable angina. METHODS The initial population consisted of 173 patients consecutively admitted at two different Coronary Care Units with class IIIB unstable angina. Of these, 56 were excluded:(More)
Limited functional capacity has an important negative predictive value both in normal subjects and in patients with heart disease. In heart failure patients the improvement in physical capacity produces an increase in survival and a reduction in morbidity and hospital admission. The main cause of physical capacity reduction in heart failure elderly patients(More)
