Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

to apply angiography-based quantitative blood flow ratio to quantify the severity of the stenosed coronary artery prior to percutaneous coronary intervention, and monitor per-procedural myocardial injury based on the troponin level.Finally, to find the relationship between quantitative blood flow ratio results and myocardial injury degree.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* unstable angina patients

Exclusion Criteria

* (1) multivessel diseases needed to be bypassed; (2) no track of high-sensitivity troponin I (hs-CTNI) level after PCI; (3) the elevated hs-CTNI level before PCI; (4) patients refusal to PCI; (5) side branch occlusion after PCI; (6) PCI failure with the main vessels occlusion; (7) eGRF (estimated glomerular filtration rate) less than 30ml/min/1.73m2; (8) no acquisition of QFR results because of the non-ideal angiographic quality.
