The reversible defect change ≥ 5 after treatment (including medical treatment and reperfusion) is a significant independent factor for predicting MI, mortality with HR: 1, 634, 95% CI: 1, 198 - 2, 228, p = 0.0019 in multivariate analysis. 23 Patients with The reversible defect change ≥ 5 should be closely monitored with optimally optimized medical treatment and consider invasive screening tests to treatment decision.
