Abstract

Background: To detect the potential in hospital prognostic value of fQRS complex in patients with acute coronary syndrome (ACS) & investigate whether FQRS complex can be used to distinguish patients with early NSTEMI from those with unstable angina. Methods: It included 150 patients with acute NSTEMI and unstable angina. All patients were subjected to Grace score calculation, ECG to detect ischemic changes and detect presence or absent of fQRS, transthoracic echo to detect LV ejection fraction and recording in-hospital outcome. Results: Patients with fQRS have significant higher Killip class>2, higher troponin &CKMB levels, higher grace score, increased LVEDD & LVESD and significantly lower LVEF%. LVEF is significantly lower among patients with fQRS than patients with not fQRS in NSTEMI patients while there is no significant difference of LVEF % between both groups in unstable angina patients. There is significant association between fQRS and higher prevalence of NSTEMI and higher incidence of heart failure, arrhythmia and bad outcome. By multivariate analysis, NSTEMI (p =0.003) and high HR (p =0.004) and fragmented QRS (p =0.00) were the only significant predictors for bad outcome. FQRS have the ability to diagnose NSTEMI in 47.9% of cases, fQRs can truly exclude NSTEMI in 72.7% of case. Conclusion: Among patients with ACS, the presence of fQRS was associated with an increase incidence of complication, worse outcome, larger LV dimensions, and lower LVEF. The presence of fQRS in acute coronary syndrome patients could predict the presence of NSTEMI with fair diagnostic value.
