CAD, coronary artery disease; eGFR, glomerular filtration rate estimated using the Cockroft-Gault formula; LAD, left anterior descending coronary artery; LCx, left circumflex coronary artery; LV, left ventricle; PCI, percutaneous coronary intervention; RCA, right coronary artery; STEMI, ST-segment elevation myocardial infarction.

^*Serum total cholesterol ≥230 mg/dL and/or serum triglycerides ≥200 mg/dL or treatment with lipid-lowering drugs.

^†Defined as systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg and/or the use of antihypertensive medication.

^‡Complete revascularisation was defined as treating all present significant coronary artery stenosis ≥70% during primary PCI or before discharge.

A two-sided p value of <0.05 was considered statistically significant.
