Chinese Herbal Medicine Dingji Fumai Decoction for Ventricular Premature Contraction: A Real-World Trial

الملخص EN

Background.

Chinese herbal medicine Dingji Fumai Decoction (DFD) is widely clinically used for ventricular premature contraction (VPC).

This real-word trial was designed to assess the safety and effectiveness of DFD for VPC.

Methods.

This was a double-blinded, randomized placebo-controlled trial.

Patients with VPC were randomized (1 : 1) to treatment with DFD combined with metoprolol (DFD arm) or metoprolol combined with placebo (MET arm).

A primary end point was a composite of clinical symptoms and signs determined by the traditionalChinese medicine syndrome score and the number of VPC determined by the Holter examination.

Second outcomes were adverse events, medication compliance, and laboratory examination.

Results.

144 patients were randomized to DFD arm (76 patients) or MET arm (68 patients), and 136 cases (71 in DFD arm and 65 in MET arm) finally completed this trial.

After a 12-week follow-up, DFD arm significantly decreased traditional Chinese medicine syndrome score and the number of VPC compared with MET arm (P=0.003 and 0.034, respectively).

There was no adverse drug effect and patient medication compliance was good.

Conclusions.

Superiority with DFD arm for VPC was demonstrated over MET arm for both the safety and effectiveness end points.
