highly significantP <0.001
LV mass indexed by BSA as a continuous variable was highly significant associated with infarct size ( r =0.3; P <0.001), LVEF ( r =0.4; P <0.001), myocardial salvage index ( r =0.3; P <0.001), and the combined endpoint of all‐cause mortality and readmission for heart failure (HR, 1.03 [95% CI, 1.01–10.5]; P =0.005).
