Heart failure (HF), a clinical syndrome most commonly occurring due to ischemic heart disease, causes significant morbidity and mortality. The benefits of revascularization versus medical treatment for ischemic heart failure remain controversial. Thus, we assessed a patient diagnosed with ischemic heart failure before and 3 months after coronary artery bypass grafting by myocardial radionuclide imaging. Findings of Tc-99m sestamibi myocardial perfusion imaging revealed that the degree and area of ischemia were significantly reduced, and the systolic function of the left ventricle improved compared with the preoperative value. This suggests the benefit of revascularization in cases of ischemic heart failure.
