Coronary microcirculatory dysfunction has been known to be prevalent even after successful revascularization of acute myocardial infarction (AMI) patients, and has been shown to be associated with poor prognosis. Angiography derived index of micro-circulatory resistance (Angio-IMR) is a novel pressure-wire free approach to assess coronary microvascular disease with great diagnostic performance. The current study will further investigate the prognostic value of Angio-IMR in patients with AMI in multicenter retrospective cohort.
