Brief summary
This study compared the effect of Yangxinshi on exercise tolerance of patients with percutaneous coronary intervention (PCI) for the first time with Trimetazidine.Half of participants will receive Yangxinshi and Trimetazidine mimic tablets in combination,While the other half will receive Trimetazidine and Yangxinshi mimic tablets.
Detailed description
The Primary Purpose of this study is to compare the effect of Yangxinshi on exercise tolerance of patients with percutaneous coronary intervention (PCI) for the first time with Trimetazidine, The target patients are the people who underwent PCI for the first time and can be carried on Cardiopulmonary exercise test. The treatment period was 24 weeks. The patients were randomly divided into two groups.： A: Yangxinshi pill 3 pills /tid and Trimetazidine mimic tablets 20mg/tid B: Trimetazidine mimic tablets 20mg/tid and Yangxinshi pill 3 pills /tid The patients were followed up for 0 weeks, 4 weeks, 12 weeks, 24 weeks and 28 weeks after entering the group.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in METs assessed by the CPET | 24 weeks | MET=Metabolic Equivalent of Task; CPET=Cardiopulmonary Exercise Test |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of major cardiovascular events (MACE) | 4,12,24 and 28 weeks | — |
| PHQ-9 Depression Scale | 24 weeks | PHQ=Patient health questionaire, score range: 0-27 |
| Changes of Seattle Angina Questionnaire | 24 weeks | The Seattle Angina Questionaire (SAQ) quantifies patients'physical limitations caused by angina. The scale is transformed to a score of 0 to 100, where higher scores indicate better function (less physical limitation) |
