Fragmented QRS Complex as a Predictor of Multivessel Disease in Acute Coronary Syndrome


Background: The incidence of multivessel disease in acute coronary syndrome (ACS) is expected to be identified as early as possible in order to perform optimal management. The presence of multivessel disease can lead to ischemia or myocardial infarction. Fragmented QRS complex (fQRS) is a new electrocardiography (ECG) parameter that has been proven to be caused by ischemia or myocardial infarction.
Methods: A cross-sectional study. Patients with ACS that admitted at Dr. Wahidin Sudirohusodo Makassar since December 2014 - March 2015 who are eligible were enrolled in this study.Presence of fQRS evaluated on first 12-lead ECG at hospital admission. Presence of multivessel disease based on coronary angiography. Data were analyzed by logistic regression. Data was significant if the p-value<0.05.
Results: There are 63 subjects (56 men and 7 women) included in this study. Older age, history of ACS before, presence of dyslipidemia, and presence of fQRS were significantly more often in group with multivessel disease. After analyzed with logistic regression, the fQRS was the only significant predictor of multivessel disease with p value 0.003 and odds ratio 13.28.
Conclusion: Presence of fQRS in the first 12-lead ECG when admitted to the hospital was an independent predictor of multivessel disease in patients with ACS.
