A total of 270 patients were included by a retrospective search of the existing databases of 4 institutions. In addition to hard events, consisting of cardiac death and nonfatal myocardial infarction, any significant events including death, nonfatal myocardial infarction, coronary revascularization, heart failure, and unstable angina were assessed. During a median follow-up of 3.9 years, 33 patients had significant events, among whom 10 had hard events. Kaplan-Meier survival estimates revealed a hard event-free survival rate of 98 % at 3 years in patients with a BMIPP defect score lower than 5 but 93 % in those with a defect score of 5 or greater (P = .03). With regard to significant events, the analysis showed an event-free survival rate of 92 % at 3 years in patients with a BMIPP defect score lower than 5 but 80 % in those with a defect score of 5 or greater (P = .0003).
These results indicate that resting BMIPP imaging has prognostic value and may have a role in the risk stratification of patients with known or suspected CAD.
