BMI Body Mass Index; STEMI ST-segment elevation myocardial infarction; NT-proBNP N-terminal pro-Brain natriuretic peptide; LVEF Left ventricle ejection fraction
P-values refer to difference between groups with LTL below vs above median level; Pearson’s chi square or Mann-Whitney U test
^a Defined as previous diagnosis of hypertension
^bDefined as previous diagnosis of hyperlipidemia
^cCreatinine > 150 μmol/L
