Exclusion criteria:

1. Unprotected left main disease; 2. Hemodynamic instability; 3. History of recurrent myocardial infarction or coronary artery bypass grafting; 4. Aortic dissection is clearly, highly suspected, or cannot be ruled out; 5. Patients who have undergone intravenous thrombolysis; 6. Severe calcification, angulation or distortion of coronary arteries, and it is expected that the dual lumen microcatheter or aspiration catheter cannot pass through the target lesion; 7. Previous history of intracranial hemorrhage or ischemic stroke within 3 months; 8. Active bleeding or bleeding factors (including menstruation); 9. Severe trauma or major surgery within 3 weeks or bleeding in areas that cannot be compressed; 10. Severe or poorly controlled hypertension (SBP>180mmHg and/or DBP>110mmHg); 11. Known allergy to any drugs that may be present in the study; 12. Women who are pregnant, breastfeeding or at risk of becoming pregnant; 13. Complicated with severe lung disease, liver and kidney insufficiency; 14. Patients with malignant tumors or expected survival time < 6 months; 15. Long-term use of anticoagulant drugs (such as warfarin, rivaroxaban, etc.); 16. Contraindicated cardiac magnetic resonance examination; 17. The patient also participated in other clinical studies; 18. Subjects deemed unsuitable for inclusion in this study by the investigator.
