A Study on Yiyang Huoluo Decoction in the Treatment of Coronary Heart Disease

March 23, 2026 updated by: Xia Liang

Clinical and Basic Research on the Treatment of Senile Atherosclerosis and Coronary Heart Disease With Yiyang Huoluo Decoction

The goal of this clinical trial is to learn if Yiyang Huoluo Decoction (a custom Chinese herbal medicine) works safely and effectively to treat coronary heart disease with atherosclerosis in older adults. It also aims to find out how this herbal treatment may affect blood vessel health and repair at a cellular level.

The main questions it aims to answer are:

  • Does adding Yiyang Huoluo Decoction to standard Western medical care improve symptoms and heart-related health in older adults with coronary heart disease and atherosclerosis?
  • Is Yiyang Huoluo Decoction safe for older adults to take alongside their regular heart medications?
  • How does this herbal treatment affect the damaged blood vessels in study participants?

Researchers will compare two groups of participants to see if the combined treatment works better than standard care alone.

Who can take part: Older adults diagnosed with coronary heart disease and atherosclerosis who meet the study's health and eligibility rules.

What participants will do:

  • Be split randomly into two groups of 15 people each: one group gets standard Western heart medicine only, and the other gets standard Western heart medicine plus Yiyang Huoluo Decoction (herbal granules)
  • Complete the 12-week decoction treatment plan as directed by the research team
  • Attend scheduled study visits for health checks, blood tests, heart and blood vessel scans (such as carotid ultrasound and coronary CTA), and symptom reviews
  • Provide two small blood samples for research testing (samples will be destroyed after study testing is finished)
  • Report any side effects, discomfort, or changes in health to the research team right away

All personal health information collected for this study will be kept private and confidential. Participation is completely voluntary, and participants may quit the study at any time for any reason without losing access to regular medical care.
