Identification of therapeutic benefit from revascularization in patients with left ventricular systolic dysfunction: inducible ischemia versus hibernating myocardium.
BACKGROUND Although the recent surgical treatment of ischemic heart failure substudy reported that revascularization of viable myocardium did not improve survival, these results were limited by the viability imaging technique used and the lack of inducible ischemia information. We examined the relative impact of stress-rest rubidium-82/F-18 fluorodeoxyglucose positron emission tomography identi...
متن کاملGlucose metabolism as a marker of myocardial ischemia
Although the heart is omnivorous, glucose becomes the key substrate under conditions of stress. The utilization of exogenous glucose by the myocardium can be assessed non-invasively using positron emission tomography (PET) with the glucose analogue F-fluorodeoxyglucose (FDG). Several studies have demonstrated that glucose utilization is increased at peak stress and during conditions of reduced ...
متن کاملDobutamine stress echocardiography identifies hibernating myocardium and predicts recovery of left ventricular function after coronary revascularization.
BACKGROUND The identification of hibernating myocardium is important in selecting patients who will benefit from coronary revascularization. This study was performed to determine whether dobutamine stress echocardiography (DSE) could identify hibernating myocardium and predict improvement in regional systolic wall thickening after revascularization. METHODS AND RESULTS DSE was performed in 49...
متن کاملTime course of functional recovery of stunned and hibernating segments after surgical revascularization.
BACKGROUND Recovery of function is possible in patients with ischemic cardiomyopathy when left ventricular dysfunction is caused by stunning or hibernation. It is plausible that recovery of function after revascularization may take a longer time in hibernating myocardium compared with stunned myocardium. Accordingly, the time courses of functional recovery in hibernating and stunned myocardium ...
متن کاملA Comparison of Thallium-201 Spect and F-18 Deoxyglucose Positron Emission Tomography in Assessing Myocardial Viability
Assessment of myocardial viability 1>rior to revascularization procedures is an important clinical consideration for improved functional recovery of regional left ventricular dysfunction. In chronic coronary artery disease, impaired left ventricular function , at least in part, is due to ischemic or hibernating myocardium rather than just myocardial fibrosis. Functional recovery of the left ven...
