OP-80 Fragmented QRS as a Cautionary Signal of Mortality in Non ST elevation Patients




Objective


Early diagnosis and identification of high risk non-ST elevation myocardial infarction (NSTEMI) is an important issue. Fragmented QRS (fQRS) complexes are defined as various RSR’ patterns on 12-leads resting electrocardiography (ECG). Previous studies revealed that fQRS is related with increased ventricular arrhythmias and cardiovascular mortality. The relation between fQRS and mortality in acute coronary syndromes, mitral valve disease severity and structural heart disease has been shown in different studies. The aim of this study was to investigate relation between fQRS and early (1 month) and late cardiovascular mortality (12 month) in NSTEMI patients.




Methods


Patients who admitted to our emergency unit and diagnosed NSTEMI between May 2012 -January 2013 were included prospectively. All patients evaluated for their clinical, laboratory, electrocardiographic characteristics. Angiographic features of 315 patients (72.7%) who underwent coronary angiography was also recorded.

Results


Of 433 patients (67% men, mean age 62.3±12.8 years), fQRS complexes determined in 85 patients. Patients were divided into two groups according to fQRS existence. Demographic characteristics and cardiovascular risk factors were similar in both groups except dyslipidemia. Coronary angiographic characteristics and coronary revascularization rates were similar in both groups. Left ventricular ejection fraction was significantly lower in fQRS (+) patients (45.1% vs 50.5%, p=0.002). Early mortality was found similar in both groups (2.4% vs 2.6%, p=1.0), however late mortality was higher (15.2% vs 5.4%, p=0.006) in fQRS group (Table-1).
