Xu S, et al. - Given that early repolarization (ER) conferring risk for ventricular tachyarrhythmias (VTAs) in acute myocardial infarction (AMI) patients has been reported in many studies, researchers focused on the prognostic values of ER detail features except J-point morphology, and inferior leads ER location for VTAs. They analyzed 10 studies, including 2,672 participants, identified from PubMed, Embase, and the Cochrane Library. This analysis included studies assessing the link between ER and the incidence of VTAs in AMI patients. As per the findings, the incidence of VTAs was significantly predicted by ER, irrespective of the type of AMI. In the long follow-up (≥ 30 days), a decline in the prognostic value of ER for VTAs by half was observed when compared with short follow-up duration (< 30 days). Findings revealed a significant link of ER with increasing risk of VTAs, especially ventricular fibrillation, in AMI patients. This link was not strengthened by J-point elevation and lateral leads’ ER location.
