Controversy exists regarding the relative status of resting myocardial blood flow (MBF), coronary flow reserve (CFR), and contractile reserve (CR) in hibernating myocardium (HM). We hypothesized that CFR is more profoundly affected than resting MBF parameters in HM. Thus, resting MBF assessed by myocardial contrast echocardiography (MCE) will be more sensitive than CR elicited by dobutamine stress echocardiography (DSE) for the detection of HM.
