NLRP3 and Ventricular arrhythmia: In a previous study by our team, cinnamaldehyde significantly improved ISO-induced acute myocardial injury and postischemic ventricular arrhythmia, which is in line with the results reported by Song F and Mehrnoosh et al. [12, 13] Based on previous research, this paper focused on the mechanism of ventricular arrhythmia and the effect of cinnamaldehyde on the TAK1-p38MAPK-NLRP3 signalling pathway from the perspective of inflammation to provide new ideas and a basis for clinical treatment and new drug research and development.
