Predictive value of neutrophil/lymphocyte ratio in predicting complications after non st elevation myocardial infraction

ABSTRACT

A Cross sectional study conducted in Cardiology Unit, Hayatabad Medical Complex from August 2011 to February 2012. In a total of 250 patients with non ST elevation MI were enrolled in study. Neutrophil to lymphocyte ratio [NLR] was determined. Those with high NLR were followed over two week period to detect in hospital mortality; Atrial Fibrillation and ST segment Deviation. Association of cellular response with the incidence of post-MI mortality/complications was assessed by multiple logistic regression analyses. There were 250 patients comprising of 154 [61.60%] males and 96 [38.40%] females. The overall mean age was 51.57 +/- 12.5 years. The frequency of high neutrophil to lymphocyte ratio was present in 78 [31.20%] patients. The In hospital mortality and atrial fibrillation rate was in 10.26% and 11.54% cases respectively while ST segment deviation was in 57.69% patients. Patients with Non ST Segment elevation Myocardial Infarction with high Neutrophil to lymphocyte ratio, is a good predictor of In hospital mortality, atrial fibrillation and ST segment deviation. Thus a single CBC analysis may help to identify Non- STEMI patients at risk for mortality and complications.
