All patients were monitored for the occurrence of POAF with continuous electrocardiographic telemetry until the day of discharge from the hospital.
The binary logistic regression analysis with enter method was used for all relevant independent variables predictive of POAF with a p value <0.
Patients with POAF had lower left ventricular EF (p<0.
While non-AF group had higher statin use, POAF group had higher usage of calcium channel blockers.
001) were independent predictors of POAF (Table 3).
The sensitivity and the specificity of FQRS for detecting POAF in the study participants were evaluated by ROC analysis.
We revealed a significant association between new-onset POAF and pre-operative, operative and postoperative poor prognostic factors and the presence of fQRS.
POAF is associated with increased mortality and morbidity following CABG (19, 20).
Moreover, QRS time was not a predictor for POAF independent of fQRS in our study.
POAF is a clinically important and common postoperative complication, and previous studies have shown that prophylaxis may be possible with treatments such as beta-blockers, sotalol, amiodarone and possibly magnesium (37, 38).
If we speculate, the potential common pathophysiological mechanisms for POAF may be elevated ventricular filling pressure due to abnormal LV diastolic and systolic functions as well as ischemia; all of which have been related to the presence of fQRS in previous studies.
Fragmentations on preoperative ECG may be useful in identifying patients at higher POAF risk whom will need additional support after their operations.
