Non-infarct related artery microvascular obstruction is associated with worse persistent diastolic dysfunction in patients with revascularized ST elevation myocardial infarction

Background Infarct-artery (IRA) microvascular obstruction (MVO) is associated with diastolic dysfunction (DD) in STEMI patients. However, association between nonIRA MVO and DD in STEMI patients remains unknown. We hypothesized that revascularized STEMI patients with IRA and nonIRA MVO (IRA + nonIRA+), compared to those without nonIRA MVO (IRA + nonIRA-), have worse DD at presentation and long-term follow-up. Methods 87 IRA-revascularized STEMI...
