NCT00975858
The randomized comparison of two strategies in coronary revascularization: bypass surgery without the use of a heart lung machine and coronary stenting procedure. The comparison comprised the occurrence of cardiac adverse events after the procedure. In addition, costs, cognitive outcomes and angiography were assessed.
NCT00975494
In heart failure (HF), a defective nitric oxide (NO) signaling may be involved in left ventricular (LV) diastolic abnormalities and LV remodelling progression. PDE5-inhibition, by blocking NO degradation and overexpressing cellular cyclic guanosine monophosphate (cGMP) pathways might be beneficial. Several short term studies have demonstrated safety and clinical improvement in stable heart failure (HF) patients. The purpose of this study is to test the effects on LV diastolic function, cardiac geometry and clinical status in a cohort of HF patients.
NCT00924833
Exposure of healthy subjects to high altitude hypoxia elicits changes in cardiovascular, respiratory and metabolic features as weel as in exercise performance similar, for some aspects, to those observed in chronic heart failure. Exposure to high altitude hypoxia represents a suitable model to assess different treatments proposed for this pathological condition. Our aim was to evaluate the impact of two different third-generation beta-blockers used in heart failure (carvedilol and nebivolol) on cardiovascular, respiratory, metabolic profile and on exercise performance at high altitude.
