Chinese patent medicine Xuefu Zhuyu capsule for the treatment of unstable angina pectoris: A systematic review of randomized controlled trials.

Abstract

BACKGROUND:

Xuefu Zhuyu Capsule (XFZY) has been commonly used for relieving chest pain in patients with coronary heart disease (CHD). Randomized controlled trials (RCTs) on XFZY in treating unstable angina (UA) have not been systematically reviewed.

OBJECTIVE:

This study aims to provide a PRISMA-compliant systematic review to evaluate the efficacy of XFZY in treating UA.

METHODS:

An extensive search of 7 medical databases was performed up to June 2013. RCTs involving XFZY or combined with conventional drugs versus conventional drugs were identified. Meta-analysis was performed to evaluate the cardiovascular effects of XFZY. Rev Man 5.0 was used for data analysis.

RESULTS:

8 RCTs were included in this review. Statistical analysis of the results showed that XFZY combined with conventional drugs had significant effect on relieving angina symptoms (RR: 1.26 [1.16, 1.38]; P<0.00001) and improving ECG (RR: 1.20 [1.04, 1.38]; P=0.01) compared with conventional drugs alone. No severe adverse events were reported.

CONCLUSIONS:

XFZY combined with conventional drugs appears to have potential cardiovascular effects in treatment of UA with few adverse events. However, further rigorous designed trials are still needed.
