Shen Song Yang Xin Capsule Combined with Antiarrhythmic Drugs, a New Integrative Medicine Therapy, for the Treatment of Frequent Premature Ventricular Contractions (FPVC)‎: A Meta-Analysis of Randomized Controlled Trials

Abstract EN

Objective.

To evaluate the beneficial and adverse effects of Shen Song Yang Xin Capsule (SSYX Capsule) combined with antiarrhythmic drugs for the treatment of frequent premature ventricular contractions (FPVC).

Methods.

Seven electronic databases were searched to retrieve any potential randomized controlled trials (RCTs) designed to evaluate the clinical efficacy of SSYX Capsule combined with Antiarrhythmic Drugs for FPVC reported in any language, with total effect for FPVC and number of ventricular premature contraction as the main outcome measure.

The methodological quality of the included studies was assessed using criteria from the Cochrane Handbook for Systematic Review of Interventions, Version 5.1.0, and analysed using RevMan 5.1.0 software.

Results.

Sixteen RCTs of SSYX Capsule were included.

The methodological quality of the trials was generally evaluated as low.

The results of meta-analysis showed that SSYX Capsule combined with antiarrhythmic drugs was more effective in total effect for FPVC and number of ventricular premature contraction compared with Antiarrhythmic Drugs in patients with FPVC or FPVC complicated by other diseases.

Ten of the trials reported adverse events, indicating that the safety of SSYX Capsule is still uncertain.

Conclusions.

There is some but weak evidence about SSYX Capsule combined with antiarrhythmic drugs appearing to be more effective in total effect for FPVC and number of ventricular premature contraction in patients with FPVC and its complications.
