What this trial studies

This clinical trial investigates the efficacy and safety of Qishenyiqi dripping pills in patients suffering from microvascular angina pectoris. Participants will receive either the Qishenyiqi treatment or a placebo, with a regimen of one bag three times a day. The study includes a long-term follow-up period of one year to assess the impact of the treatment on coronary flow reserve and the occurrence of adverse cardiovascular events. The trial aims to provide insights into the potential benefits of this traditional Chinese medicine for coronary microvascular disease.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals experiencing repeated chest pain attacks with typical exertional or resting angina, and who have a coronary flow reserve of less than 2.0.

Not a fit: Patients with a history of myocardial infarction, severe arrhythmias, or significant coronary artery disease are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new therapeutic option for patients with coronary microvascular disease, potentially improving their quality of life and reducing cardiovascular events.

How similar studies have performed: While the use of traditional Chinese medicine in cardiovascular conditions is explored, this specific approach with Qishenyiqi has not been widely tested in similar studies, making it a novel investigation.
