Back to the basics: neutrophil/lymphocyte ratio in peripheral blood smear predicts morbidity/mortality in patients of acute MI following the index event.
Isra Med J Jan ;5(3):189-92.

OBJECTIVES: To find out the simple, economical and diagnostic test for detecting Acute Myocardial Infraction (AMI) at distant areas. STUDY DESIGN: Cross sectional study PLACE AND DURATION: Six months METHODOLOGY: 03 ml of blood sample was collected from 140 patients presenting to the Emergency /Coronary Care Units of hospitals viz Isra University Hyderabad, Red Crescent Hyderabad and Civil Hospital Hyderabad. The slides were prepared and white blood cells were counted microscopically at Post Graduate laboratory of Isra University Hyderabad. RESULTS: In present study Neutrophil/Lymphocyte (N/L) ratio was observed and compared in both subjects (cardiac and non-cardiac). The N/L ratio was found to be normal in non-cardiac patients but was significantly raised in patients with myocardial infarction. Especially in Acute Myocardial Infarction with ST segment elevation (AMI-STE) in comparison to Acute Myocardial Infarction with non ST segment elevation (AMI-NSTE) was also observed (p< 0.001). CONCLUSION: The N/L ratio was significantly raised in patients with AMI suggesting an additional diagnostic parameter for AMI at primary health care units.
