5. Visual assessment of target lesion stenosis ≥70%, TIMI blood flow≥ 1;
6. Subject who understand the purpose of testing, voluntary and informed consent, patients undergoing invasive imaging follow-up.
Exclusion Criteria:
* Patients will be excluded if any of the following conditions apply:
General:

7. Patients have ischemic stroke half a year before implantation, patients have transient ischemic attack 3 months before implantation, patients have high coagulation tendency judged by investigator or laboratory examination;
8. Bleeding, active gastrointestinal ulcers, brain hemorrhage or subarachnoid hemorrhage, contraindications on antiplatelet agents and anticoagulant therapy; patients would not allow to undergoing antithrombotic therapy;
9. Aspirin, clopidogrel, heparin, contrast agent, poly lactic acid polymer, rapamycin and metal allergies;
10. Patients who have a history of disease related to iron overload or iron disorder, such as hereditary hemochromatosis, etc;
11. The patient's life expectancy is less than 12 months;

Exclusion criteria by angiography:
1. Chronic total occlusion (TIMI blood flow=0 before implantation) , left main coronary artery lesion, ostial lesion, multiple vessel lesion, branch lesion and bridge lesion which branch vessel diameter ≥ 2.0 mm (if the ostium of branch vessel stenosis \>40% or needs balloon predilation); visible thrombus in target vessels;
2. Severe calcified lesions and distorted disease which unable to predilation, lesion not suitable for stent delivery and expansion;
3. In-stent restenosis;
4. Myocardial bridge is involved in target lesion;
5. In order to reach the target lesion, study stent has to go through the previous implanted stent;
6. Predilation balloon can't expand completely in target lesion site, judgment standard for fully expansion as below, patients are excluded when do not meet any item:
A. DS% \< 40%（visual），highly recommend DS% ≤20% B. TIMI blood flow= class 3（visual） C. No angiography complications (e.g., distal embolization, lateral branch closed) D.
