Bold text indicates a statistically significant difference with a P value less than 0.05.
CI = confidence interval; cTnI = cardiac troponin I; fQRS = fragmented QRS; HR = hazard ratio; IVS = interventricular septum; LV = left ventricle; LVEF = left ventricular ejection fraction; NYHA = New York Heart Association; RBBB = right bundle branch blocker; RV = right ventricle; TAPSE = tricuspid annular plane systolic excursion.
