LVEF: left ventricular ejection fraction; AMI: acute myocardial infarction; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol; eGFR: estimated glomerular filtration rate. The odds ratio (OR) with 95% confidence interval (95% CI) of various factors associated with LVEF <50% was produced using multiple logistic regression analysis.
