Prognostic significance of fragmented QRS in patients with ST-elevation myocardial infarction undergoing revascularization.

ABSTRACT:

Background & objectives

This longitudinal study was carried out to evaluate the prognostic significance of fragmented QRS (fQRS) in patients with acute ST elevation myocardial infarction (STEMI) undergoing revascularization.

Methods

This study included 103 STEMI patients belonging to Killip class I and II who underwent primary revascularization. All patients underwent twelve lead ECG at admission before PCI. Serial ECG were done after PCI at 3 hours, 6 hours, 24 hours, 48 hours and at discharge for detection of fQRS and echocardiography on day 3 post revascularization. Patients developing fQRS within 48 hours and with persistence of fQRS till discharge were included in "persistent fQRS" group. They were followed up after 30 days for major adverse cardiac events (MACE) and as
