Abstract:
Objective To study the prognostic value of fragmented QRS (fQRS) in the recurrence of cardiac events in acute STEMI patients underwent emergency percutaneous coronary intervention (PCI). Methods Ninety-two acute STEMI patients who underwent emergency PCI were enrolled. The presence of fQRS was evaluated by a 12-lead ECG in 72 h after PCI. Cardiac events (myocardial infarction, need for revascularization or cardiac death) and all-cause mortality were recorded in all patients during 12 months follow-up. Results Cardiac event rate[15 (31.3%) vs. 4 (9.1%)]were higher in the fQRS group (n=48) compared with the non-fQRS group (n=44) during a mean follow-up of 12 months. A Kaplan-Meier survival analysis revealed significantly lower event-free survival for cardiac events in the fQRS group (P < 0.004). The results of Cox regression model analysis revealed that signiifcant fQRS was an independent signiifcant predictor for cardiac events (HR 2.19, 95%CI 1.38-3.50, P=0.023). Conclusions The presence fQRS is an independent risk factor for poor prognosis in STEMI patients undergoing emergency PCI.
