Summary

Coronary microvascular dysfunction (CMD) is increasingly recognized as an important indicator for long-term prognosis in patients with acute myocardial infarction (AMI). The angiography-derived index of microcirculatory resistance (angio-IMR) is a novel guidewire-free measure for CMD in patients with AMI. Ticagrelor has recently been suggested to have additional benefits on coronary microcirculation beyond its antiplatelet effect. This study was designed to compare the protective effects of ticagrelor and clopidogrel on CMD and prognostic impact in patients with AMI, using the angio-IMR as a novel assessment tool.
