We studied heart rate variability in 14 healthy women before and after oophorectomy compared with 14 matched women who underwent hysterectomy with ovarian conservation. Surgical menopause induced a decline in cardiac vagal modulation with a shift toward sympathetic hyperactivity. Recovery of the baseline condition after 3 months of estrogen replacement(More)
BACKGROUND Metabolic syndrome is a cluster of common cardiovascular risk factors that includes hypertension and insulin resistance. Hypertension and diabetes mellitus are frequent comorbidities and, like metabolic syndrome, increase the risk of cardiovascular events. Telmisartan, an antihypertensive agent with evidence of partial peroxisome(More)
A phase II, open, nonrandomized trial was carried out in a group of epirubicin-treated patients with cancer at different sites with the aim of detecting early preclinical changes that are predictive of the risk for heart failure. All patients underwent conventional echocardiography, as well as tissue Doppler imaging (TDI) with strain (sigma) and strain rate(More)
BACKGROUND Patients with diabetic cardiomyopathy have an impaired myocardial glucose handling and distal distribution of coronary atherosclerosis. Trimetazidine, an anti-ischemic metabolic agent, improves myocardial glucose utilization though inhibition of fatty acid oxidation. Aim of the present study was to evaluate whether the metabolic effect of(More)
OBJECTIVES We prospectively investigated the relationship of circulating endothelial progenitor cells at time of percutaneous coronary intervention to the subsequent development of in-stent restenosis or progression of coronary atherosclerosis. BACKGROUND Endothelial progenitor cells provide an endogenous repair mechanism of the dysfunctional endothelium(More)
We studied the relationship between left ventricular (LV) function and the increased LV mass in 18 highly trained rowing athletes (14 men, 4 women; mean age 20.7 +/- 4.5 years) using pulsed wave Doppler tissue imaging (PWDTI). Thirteen untrained volunteers, matched for age and body mass index, acted as control participants. Peak systolic, early diastolic(More)
As recently claimed, TSH-suppressive therapy with L-T4 may have adverse effects on the heart, but these results have not been consistently confirmed. We assessed cardiac function by clinical, echocardiographic, and ergometabolic criteria in 19 patients (16 women and 3 men) receiving long term L-T4 at a fixed daily dose ranging from 1.8-4.0 microg/kg. The(More)
The changes in extracellular concentrations of noradrenaline (NA) in the prefrontal cortex of morphine-dependent rats were studied by microdialysis following an acute morphine challenge and during naloxone-precipitated withdrawal. Animals were implanted with morphine- or placebo-containing pellets for 5 days. In control rats a challenge dose of morphine (5(More)
Peripheral vascular responses to acute administration of natural progesterone were studied in 12 postmenopausal women (mean +/- SD age 50.3 +/- 4.8 years) with no evidence of cardiovascular disease. According to a randomized, double-blind protocol, all subjects were given natural progesterone as a vaginal cream, able to produce a rapid peak and decay of(More)
BACKGROUND Oxidative stress and RAAS play an important role in the occurrence of anthracyclines-induced cardiotoxicity. Telmisartan, an angiotensin II type 1 receptor blocker, inhibits activation of superoxide sources and induces anti-inflammatory effects. METHODS The possible role of telmisartan in preventing myocardial damage induced by epirubicin (EPI)(More)
