Table 4 Independent predictors of complete EF recovery: univariate logistic regression model

From: Clinical course, viral etiology, and the diagnostic workup for patients with suspected myocarditis: a single-center prospective study

Predictor OR (95% CI) P value
Presence of localized SWMA 9.7 (2.1–44.2) = 0.003
Myocarditis by CMR 4.7 (1.9–24.7) = 0.04
Decreasing LA size/cm 0.277 (0.072–0.963) = 0.047
Increasing ESC PSC 0.51 (0.25–1.03) = 0.06
Residence (Rural) 3.6 (0.86–15.5) = 0.07
COVID Status (Positive) 0.46 (0.1–2.06) = 0.31
Age/years 0.963 (0.914–1.015) = 0.22
Sex (Male) 1.3 (0.36–4.8) = 0.66
Seropositive 0.993 (0.221–2.459) = 0.469
DM 1.5 (0.19–11.9) = 0.68
HTN 0.72 (0.06–8.5) 0.79
  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
