BACKGROUND Computed tomographic pulmonary angiography (CTPA) has simplified the diagnostic approach to patients with suspected pulmonary embolism (PE). However, PE diagnosis is still probabilistic and CTPA should be used with caution in some patient groups, such as patients with severe renal insufficiency and pregnant women. Among alternative imaging tests,(More)
Experimental studies demonstrated that mineralocorticoid antagonists prevent or reverse myocardial fibrosis. Therefore, we tested the hypothesis that the aldosterone antagonist canrenone can improve left ventricular diastolic function in essential hypertension. Using digitized M-mode echocardiography and 24-hour blood pressure monitoring (ABPM), we realized(More)
BACKGROUND Aim of the study was to evaluate the role of atrial (ANP) and brain natriuretic peptides (BNP) as markers of preclinical cardiac disease in obesity. METHODS We selected 26 obese (BMI > 29 kg m(-2)) never-treated hypertensives (24-h BP > 140 and/or 90 mmHg), 26 obese normotensives (24-h BP < 130/80 mmHg) and 25 lean (BMI < or = 25 kg m(-2))(More)
Treatment with statins requires close monitoring of serum creatine kinase (CK) levels to prevent myopathy, a common and potentially serious dose-dependent adverse effect of these drugs. We have investigated the correlation between elevated CK levels and polymorphisms in the genes encoding transporters involved in statin disposition. Patients with and(More)
To verify whether beta-endorphin plasma levels influence the presence of anginal symptoms, 74 consecutive male patients were studied. All patients had previously documented coronary artery disease and reproducible exercise-induced myocardial ischemia. Thirty-five patients (Group I) had a history of angina and reported anginal symptoms during exercise stress(More)
OBJECTIVE AND DESIGN Possible variations occurring in the autonomic function during a normal ovulatory cycle have been poorly investigated and it is not known whether the baroreflex sensitivity may change according to the different phases of the cycle. The aim of this study was to evaluate heart rate variability (power spectrum analysis), and baroreceptor(More)
Some studies have suggested that high levels of total white blood cell (WBC) count and C-reactive protein (CRP) may be considered as independent prognostic factors in patients with acute coronary syndromes (ACS) and/or after cardiac revascularisation by percutaneous coronary intervention or coronary artery bypass grafting surgery. Evidence on the role of(More)
PURPOSE To conduct a serial evaluation of the cardiac effects of antineoplastic therapy with 5-fluorouracil (5-FU) and low-dose folinic acid. PATIENTS AND METHODS Sixteen patients with colon-rectal carcinoma, without cardiac disease, treated with 400 mg/ m2/die of 5-FU and 20 mg/m2/die of folinic acid for five days, once a month, for six months.(More)
The relationship between obstructive sleep apnea (OSA) and atherosclerosis-related inflammation has been poorly investigated, particularly focusing on functional responses of immune cells playing a key role in atherogenesis and in comparison with control groups with similar cardiovascular risk factors which are known to be themselves associated with(More)
BACKGROUND Hypertension is a major cause of cardiovascular remodeling. In the cardiovascular system, the remodeling of the extracellular matrix is controlled by the matrix metalloproteinases (MMPs) and the tissue inhibitors of MMPs (TIMPs). The aim of this meta-analysis is to elucidate the behavior of plasma MMP and TIMP levels in hypertension and their(More)
