OBJECTIVE: The aim of this study is to determine whether coronary HIP visualized by non-contrast T1WI can predict mortality and future coronary events for primary prevention.
DESIGN, SETTING, AND PARTICIPANTS: A multicenter prospective observational study in which 660 patients with high cardiac risk estimated by risk factor categories for a Japanese urban population Suita score are recruited from 6 institutions. After CMR data are obtained, study patients are divided into 3 groups according to the PMR cutoff value of 1.4 or 1.1 as follows: PMR >1.4, PMR 1.1 to 1.4, and PMR <1.1 and follow at least 3 to 6 years until the occurrence of 1 of the following coronary events.
MAIN OUTCOMES AND MEASURES: The primary outcome is a composite of all-cause mortality, cardiac mortality, stroke, nonfatal MI, or ischemia proven unstable angina, stable effort angina, and silent myocardial ischemia, requiring coronary intervention.
ANTICIPATED RESULTS: Among the 3 groups based on PMR cutoff, the primary outcome event rate is highest in the group with PMR >1.4 and lowest in the group with PMR <1.1.
CONCLUSIONS AND RELEVANCE: Coronary HIP is significantly associated with coronary events and may thus represent a novel predictive factor for primary prevention. Among high cardiac risk patients at primary prevention, use of non-contrast T1WI to screen for coronary HIP may reduce the composite cardiovascular events.
