  1. Univariate logistic regression analysis included all available risk factors affecting the improvement of LV EF; identified that the presence of localized SWMA rather than global left ventricular hypokinesia (OR = 9.7; 95%CI = 2.1–44.2; P = 0.003), signs of myocarditis detected on CMR (OR = 4.7;95%CI = 1.9–24.7; P = 0.04) and a smaller left atrial area (OR = 0.277; 95% CI = 0.0072–0.963; P = 0.047) were independent predictors of complete LVEF recovery at 6 m. follow-up
