Criteria

Inclusion Criteria

• Patients between 18 and 80 years of age

• Must comply all the evaluations and follow-up protocols

• Clinical diagnosis of CTO detected using coronary angiography (at least one other major vessel should have exhibited no less than 75% stenosis)

• Patients should present with left ventricular ejection fraction (LVEF) above 35% determined using transthoracic echocardiography

• CTO located in an epicardial coronary artery with a reference diameter of ≥ 2.5 mm

Exclusion Criteria

• Patients have suffered from acute myocardial infarction within the previous 3 months

• Lesion located in the left main artery (stenosis ≥50%)

• Clinical diagnosis of rheumatic valvular disease

• Clinical diagnosis of severe arrhythmia

• With history of revascularization within the CTO artery

• Lesions unsuitable for PCI

• Severely abnormal hematopoietic systems, such as platelet counts <100 x 109/L or > 700 x 109/ L and white blood cell counts < 3 x 109/L

• Patients with active bleeding or bleeding tendencies (active ulcers, short-term ischemic stroke, history of hemorrhagic stroke, intracranial space occupying lesions, recent craniocerebral trauma, and other bleeding or bleeding tendency)

• Patients with severe coexisting condition including: severe renal function dysfunction [Glomerular filtration rate (GFR) less than 60 ml/min • 1.73 m2), severe hepatic dysfunction [glutamic-pyruvic transaminase (ALT) or glutamic-oxal acetic transaminase (ALT) elevated more than three times that of the upper limit of the normal reference], severe heart failure (NYHA classification III-IV), acute infectious diseases and immune disorders, tumors, surgery within 3 months, a life expectancy less than 12 months, pregnancy or planning to become pregnant, history of allergy or adverse reactions to aspirin, clopidogrel, ticagrelor, stains, contrast material, anticoagulant, or stents

• Patients cannot tolerate dual antiplatelet treatment (DAPT)

• Patients are unable to communicate due to cognitive impairment, auditory or visual impairment

• Patients are participating in another trial for medication or an apparatus and in which the main endpoint has not been reached, or plan to participate in a clinical trial within 12 months of the intervention
