Yinxingmihuan Oral Solution in Treatment of Chest Pain After PCI
- Conditions
- Chronic Stable Angina
- Interventions
- Drug: Yinxingmihuan oral solutionDrug: Placebo
- Registration Number
- NCT06224582
- Lead Sponsor
- China National Center for Cardiovascular Diseases
- Brief Summary
A prospective, multi-center, double-blind, randomized, placebo-controlled trial is conducted to evaluate the efficacy and safety of Yinxingmihuan oral solution in the treatment of chest pain after percutaneous coronary intervention (PCI) in patients with stable angina. Patients should undergo at least 1-week standardized medical treatment phase before randomization. The primary end point is the 12-week angina frequency assessed on the basis of Seattle Angina Questionnaire (SAQ) subscales. The main secondary endpoint is the improvement of anxiety assessed by Hamilton Anxiety Scale (HAMA) to evaluate its effectiveness for chest pain caused by psychological factors.
