Revascularized STEMI patients with baseline concurrent infarct related coronary artery (IRA) and nonIRA microvascular obstruction (MVO) [IRA + nonIRA+], as compared to IRA + nonIRA- MVO patients, had higher prevalence of diastolic dysfunction at baseline (40.7 vs. 6.1%, p = 0.006) and 4 years follow-up (50.0 vs. 13.0%, p = 0.05). The prevalence of grade 1 diastolic dysfunction increased (60.9–73.9%) and combined grades 2 and 3 decreased (30.4–13.0%) at follow up in patients with IRA + nonIRA- MVO. In contrast, grade 1 diastolic dysfunction decreased (77.8–61.1%) and combined grades 2 and 3 increased (8.3–22.2%) at follow up in patients with IRA + nonIRA + MVO.
