Prognosis of late versus early ventricular fibrillation in acute myocardial infarction (original) (raw)

This study evaluates the prognosis of late ventricular fibrillation (VF) in patients following acute myocardial infarction (AMI). Among 4,269 patients monitored, 413 experienced in-hospital VF, with 261 (6.8%) having early VF and 132 (3.2%) having late VF. While in-hospital mortality for early and late VF was similar, long-term survival analysis showed patients with early VF had better outcomes compared to late VF, largely influenced by associated heart failure. Findings highlight the need for prolonged monitoring to better understand VF's prognostic implications.
