Lesion-related
- Diffuse coronary artery disease in situ;
- Reference target vessel diameter of 2.5-4.0 mm and length of > 25 mm;
- Non-target vessel lesions needing to receive a successful intervention therapy first before randomization to receive treatment for target lesions (note: within the same hospitalization);

- Patients who have a previous history of intracranial neoplasms, aneurysm, arteriovenous malformation or cerebral hemorrhage;
- Patients whose life expectancy does not exceed 1 year or who are difficult to follow up clinically;
- Patients who have been scheduled to undergo elective surgery which may lead to the early discontinuation of ADP receptor antagonists;
