although systolic dysfunction is revealed as a prognostic factor in cardiac surgery , the role of diastolic dysfunction as a predictive factor is less evaluated. in this retrospective study from 872 patients that underwent isolated coronary artery bypass graft(jan 2008-feb 2009),388 patients had normal left ventricular ejection fraction (>50%). these are divided in two groups, group 1: 361 pati...

Proinflammatory stimuli produce expression of inducible NO-synthase (iNOS) within blood vessels and are associated with impaired endothelium-dependent relaxation. Gene transfer of iNOS was used to test the hypothesis that expression of iNOS in blood vessels produces impairment of NO-dependent relaxation as well as contraction. An adenoviral vector containing cDNA for murine iNOS, AdCMViNOS, and...

BACKGROUND Vascular abnormalities are a major cause of postoperative complications in irradiated tissues. Endothelial cell dysfunction characterized by diminished endothelium-dependent relaxation may be involved. We examined the endothelium-dependent relaxation and morphology of the endothelium in irradiated human cervical arteries. METHODS AND RESULTS Irradiated arteries were taken from the ...

The relation of impaired left ventricular relaxation, as measured by prolonged isovolumic relaxation time, to ventricular systolic function in hypertension remains uncertain in population-based samples. In the Hypertension Genetic Epidemiology Network (HyperGEN) Study, echocardiograms were analyzed in 1457 hypertensive participants without diabetes, $21 valvular regurgitation, or coronary disea...
