Li X, Guo D, Zhou H, et al. - In this study, the effects of oxidative stress, pro-inflammatory microparticles, and pro-inflammatory cytokines on recurrent ventricular arrhythmias (VA) were explored in elderly patients after coronary stenting. Researchers recruited a total of 613 consecutive elderly patients with recurrent ventricular arrhythmias induced by coronary reocclusions after coronary stenting. After coronary stenting, high levels of pro-inflammatory microparticles, pro-inflammatory cytokines, and oxidative stress markers were associated with recurrent VA in elderly patients. The outcomes implied that the pro-inflammatory microparticles, pro-inflammatory cytokines, and oxidative stress may simultaneously induce and aggravate recurrent VA in elderly patients after coronary stenting.
