Cardiac perfusion imaging is a recognized method for non-invasive evaluation for myocardial ischemia. There is currently limited report of myocardial perfusion applied in heart failure. In this study of tachycardia-induced heart failure in swine, perfusion shows delayed arrival time, delayed peak time, and reduced slope of enhancement in myocardium.
