dose impaired relaxation of left ventricle affect early outcomes
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...

going dobutamine-stress (2). However, the PET technique enabled us to detect very early changes in myocardial blood flow before these clinical signs of ischemia eventually developed. Since we know that the presence of clinical signs of ischemia are inconsistent, subjective and variable in the same patient, we decided to focus on quantifiable, regional measures of myocardial blood flow. In contr...
متن کاملTransmural myocardial deformation in the ischemic canine left ventricle.
The myocardium is a complex three-dimensional structure consisting of myocytes interconnected by a dense collagen weave that courses in different directions. Regional ischemia can be expected to produce complex changes in ventricular deformation. In the present study, we examined the effects of ischemia on two- and three-dimensional finite strains during acute transmural myocardial ischemia in ...
متن کاملLeft ventricle restoration in end stage ischemic dilated cardiomyopathy
Background Patients with end stage dilated cardiomyopathy exhibit extensive remodeling of the left ventricle, annular dilation, and significant mitral and tricuspid regurgitation. These changes increase perioperative morbidity and mortality, and emphasize patient candidacy for heart transplantation. We previously published that Reductive Annuloplasty of Double (mitral and tricuspid) Orifices co...
متن کاملGestational diabetes influences the expression of hypertrophic genes in left ventricle of rat’s offspring
Objective(s): Gestational diabetes increases the risk of congenital heart disease in the offspring, but the molecular mechanism underlying this process remains unclear. Therefore, the current study was conducted to assess the effects of induced gestational diabetes on expression of some involved genes in cardiac hypertrophy in the offspring of diabetic rats.Materials and Methods: Diabetes was i...
