A small group of sixty patients with stable coronary artery disease joined this research project. These individuals also met specific criteria related to traditional Chinese medicine concepts like qi deficiency and blood stasis. They received either the herbal Shenqi Yangxin Formula or a fake pill, plus their usual heart medications. Neither the patients nor the doctors knew who got which treatment during the study.
The main goal was to check heart health after twenty-four weeks. Scientists used special imaging to measure blood flow around the heart and look at the fat inside the plaque buildup. They also checked how the heart muscle pumped blood and how patients felt with their chest pain. Other tests looked at metabolic changes and safety.
Follow-up visits happened at four, twelve, and twenty-four weeks to track progress. The team carefully watched for any side effects or serious problems, but the report did not list any specific safety issues found yet. This research might offer a new way to help heart patients feel better alongside their regular treatment plan.
