PCI: percutaneous coronary intervention; CABG: coronary artery bypass graft surgery; coronary artery: LM (left main); LAD: left anterior descending; RCA: right coronary artery; CX: circumflex artery; LVEF: left ventricular ejection fraction. Right ventricular (RV) dysfunction was defined as a right ventricular ejection fraction ≤ 45% severe pulmonary hypertension (PH), defined by >50 mmHg after right catheterisation measurements.
