Objective: This study evaluates the therapeutic effects of the Yangxin Huoxue Formula in the management of stable angina pectoris associated with Qi deficiency and blood stasis syndrome, co-occurring with anxiety and depressive disorders. The primary objective is to determine its efficacy in enhancing cardiac function and reducing emotional symptoms.
Methods: A randomized, single-blind, placebo-controlled clinical trial was conducted with 94 individuals with stable angina pectoris. Participants were randomly allocated to either a treatment group receiving Yangxin Huoxue Formula granules or a placebo group receiving placebo granules, administered twice daily over a 12-week period. Primary outcome measures included assessments of cardiac function, angina frequency, PHQ-9 and GAD-7 scores, traditional Chinese medicine (TCM) syndrome improvements, and inflammatory markers.
Results: The treatment group exhibited significantly greater improvements in cardiac output and reductions in peripheral vascular resistance compared to the placebo group. Additionally, a significant decrease in the frequency and duration of angina episodes was observed in the treatment group. Improvements in TCM syndrome scores and GAD-7 scores were also notably superior in the treatment group. No significant adverse reactions were recorded during the safety assessment of the treatment group.
Conclusion: The Yangxin Huoxue Formula demonstrates efficacy in improving cardiac function, alleviating symptoms of anxiety and depression, reducing inflammatory mediator release, and enhancing quality of life in individuals with stable angina pectoris. The treatment was well-tolerated, confirming both its safety and therapeutic effectiveness.
