An impaired myocardial perfusion state after primary angioplasty is a strong predictor of long-term adverse outcomes in patients with STEMI. We assessed the relationship between culprit plaque characteristics and myocardial perfusion state after primary angioplasty in patients with ST-segment elevation myocardial infarction (STEMI). ⋯ Culprit plaque with large plaque burden and high NC volume is closely associated with poor STR after revascularization.
