Abstract

Objective: To determine the prognostic value of myocardial ischemia, function and coronary risk factors on total and hard cardiac events using myocardial perfusion imaging in a Japanese population. Methods: A prospective cohort study was performed in 117 Japanese hospitals, each with a nuclear cardiology facility. A total of 4,031 patients with suspected or confirmed ischemic heart disease were registered. The patients were followed up for a year to investigate total and hard events, and those who had any events were followed up for 3 years to evaluate subsequent hard events. A stress-rest gated myocardial perfusion study was performed with 99mTc-tetrofosmin using gated single-photon emission computed tomography (SPECT) and analyzed by semi-quantitative scores. Results: During the 1-year follow-up period, 263 (6.5%) patients had total events comprising all-cause death, non-fatal myocardial infarction (MI), heart failure, unstable angina, angina pectoris and coronary revascularization. Cardiac death occurred in 23 patients (0.6%) and non-fatal MI in 11 (0.3%). Among patients with ejection fraction (EF) of
