Coronary Arterial Disease (CAD)
Conditions
Brief summary
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.

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.
