Coronary heart disease is one of the most serious diseases that endanger people's health. Complex coronary artery disease is critical and has high mortality. Therefore, it is urgent to explore the best treatment method for complex coronary artery disease. Some previous studies have shown that patients with left main coronary artery disease with a SYNTAX score> 32 points, and diabetic/non-diabetic three-vessel disease patients with coronary heart disease with a SYNTAX score > 22 points, CABG is recommended for revascularization. However, with the continuous innovation of surgical technology and the rapid development of surgical instruments, the treatment of patients with complex coronary artery disease is increasing. Therefore, it is necessary to investigate the effects of different revascularization strategies on long-term prognosis in patients with complex coronary artery disease (SYNTAX score > 22 points).

Inclusion Criteria:

1. Male/female aged 18-80 years;
