Efficacy and Safety of Metoprolol Tartrate Tablets Combined With Chinese Traditional Medicine on Premature Ventricular Complex.

Summary

Objective: investigators investigated the effects of metoprolol tartrate plus Tongmai Yangxin Pill on premature ventricular complexes and cardiac function in patients with premature ventricular complex. Methods: In total, 584 participants with premature ventricular complex will be randomly assigned (at a 1:1 ratio) into two groups: study group (metoprolol tartrate \[25 mg twice per day, orally\] plus Tongmai Yangxin Pill \[40 pills twice per day, orally\]) and control group (metoprolol tartrate \[25 mg twice per day, orally\] plus placebo \[40 simulated pills twice per day, orally\]). The total treatment period is 8 weeks. Efficacy endpoints and safety assessment: Primary efficacy endpoints are as follows: change in 24-h number of PVCs after treatment and effective rate of 24-h number of PVCs after treatment. Secondary efficacy endpoints are as follows: change in New York Heart Association classification; total effective rate of comprehensive effect; change in high-sensitivity C-reactive protein level; and change in echocardiography parameters (i.e., left ventricular ejection fraction, left ventricular end diastolic dimension, E/A, cardiac index, cardiac output, and stroke volume).
