  • Bold values indicate statistical significance at the p < 0.05 level.

  • Age=1-year increase; BMI categories=18.5–26, ≤18.5 or >26; chronic kidney disease=eGFR≥60 mL/min per 1.73 m2, eGFR<60 mL/min per 1.73 m2; Killip classification=1, 2, 3, 4; LVEF≥50%, <50%.

  • ACS, acute coronary syndrome; BMI, body mass index; eGFR, estimated glomerular filtration rate; GTN, nitroglycerin; LVEF, left ventricular ejection fraction; MACE, major adverse cardiovascular event; MI, myocardial infarction; PCI, percutaneous coronary intervention; STEMI, ST-elevation myocardial infarction.
