Does infarct-related myocardial resistance before reperfusion predict microvascular injury in patients with STEMI?
Infarct-related myocardial resistance before reperfusion may predict microvascular injury in STEMI, potentially aiding patient selection for future trials.
BACKGROUND: ) to predict MVI before reperfusion. Cardiac magnetic resonance imaging (CMR) characterizes MVI, in the forms of microvascular obstruction (MVO) and intramyocardial hemorrhage (IMH) with IMH being at the "extreme" end of the injury spectrum. METHODS: to predict MVO on CMR performed at 2-7 days. The secondary endpoint was a composite of all-cause mortality or hospitalization for heart failure up to 5 years. RESULTS: < 1000 WU groups, respectively (p = 0.06). CONCLUSIONS: is able to predict MVI in STEMI before reperfusion and may serve as a tool in future trials to select patients that might benefit most from experimental therapies.
