Randomized Controlled Trial
Effects of resveratrol on vascular tone and endothelial function of human saphenous vein and internal mammary artery.
The polyphenolic compound resveratrol presented in red wine has potent cardiovascular effect in animal. Here, we investigated the ability of resveratrol to relax human coronary bypass grafts, saphenous vein and internal mammary artery and also its effect on their endothelial reactivity. ⋯ Resveratrol produced mainly endothelium-dependent and nitric oxide-mediated vasodilation in human internal mammary artery but partially in saphenous vein rings and improved their endothelial reactivity. This may have a therapeutic potential in cardiovascular diseases.

Comparative Study
Combined right ventricular systolic and diastolic dysfunction represents a strong determinant of poor prognosis in patients with symptomatic heart failure.
The presence of right ventricular systolic dysfunction is known to significantly worsen prognosis of patients with heart failure. However, the prognostic impact of right ventricular diastolic dysfunction and of its combination with right ventricular systolic dysfunction and with other prognostic markers has not yet been systematically studied. The aim of this study was to assess the prognostic impact of combined right ventricular systolic and diastolic dysfunction in patients with symptomatic heart failure due to ischemic or idiopathic dilated cardiomyopathy. ⋯ The assessment of right ventricular systolic and diastolic function provides complementary information with a very high power to stratify prognosis of patients with heart failure. The combination of right ventricular systolic and diastolic dysfunction identifies those with a very poor prognosis.

To evaluate the performance of EuroSCORE in the prediction of in-hospital postoperative length of stay and specific major postoperative complications after coronary artery bypass grafting (CABG). ⋯ EuroSCORE can be used to predict not only in-hospital mortality, for which it was originally designed, but also prolonged length of stay and specific postoperative complications such as renal failure and sepsis and/or endocarditis after CABG. These outcomes can be predicted accurately using the standard EuroSCORE which is very simple and easy in its calculation.
