SSII incorporates the anatomical Syntax score, age, gender, creatinine clearance, left ventricular ejection fraction, peripheral vascular disease and chronic obstructive pulmonary disease

CAG: coronary angiography; CI: confidence interval; HR: hazard ratio; PCI: percutaneous coronary intervention; SAP: stable angina pectoris; SSII: Syntax score II
