Summary
This study looked at whether adding a traditional Chinese herbal powder called Yixin Powder to standard heart medications helps people with stable angina (chest pain) from coronary heart disease. 70 adults aged 40-70 with a specific Chinese medicine pattern took part. The goal was to see if the herbal mix improves symptoms and heart function better than standard care alone.
