Numerous clinical studies reported the effectiveness of herbal formula WuShen (WS) in treating cardiovascular diseases, yet relevant basic research was rarely conducted.Twelve main bioactive compounds of WS decoction were identified using the ultra-performance liquid chromatography-LTQ-Orbitrap mass spectrometer. A total of 137 active compounds with 613 targets were predicted by network pharmacology; their bioinformatic annotation and human microarray data suggested that wounding healing, inflammatory response, and gap junction were potentially the major therapeutic modules. A rat model of post-myocardial infarction (MI) heart failure (HF) was used to study the effects of WS on cardiac function, adverse cardiac remodeling, and experimental arrhythmias. Rats treated with WS led to a significantly improved pump function and reduced susceptibility to both ventricular tachycardia and atrial fibrillation, and restricted adverse cardiac remodeling partly via inhibiting TGFβ1/SMADs mediated extracellular matrix deposition and Rac1/NOX2/CTGF/Connexin43 -involved gap junction remodeling.The present study highlights that WS can be applied to the treatment of heart failure and the upstream therapy for atrial fibrillation and ventricular tachycardia through its preventive effect on adverse cardiac remodeling.
