Abstract

Background: Inflammation has an essential role in atherosclerosis that is the leading reason for acute coronary syndrome (ACS) which includes acute myocardial infarction (AMI) and unstable angina (UA). The objective of this work was to study the existence of difference in Neutrophil to Lymphocyte ratio and its relation to inflammatory markers between cases with AMI and cases with chronic coronary syndrome. Methods: This work included sixty consecutive cases with AMI and ACS who presented to cardiovascular medicine department at Tanta university hospital. The cases were classified into two equal groups; group I: cases with AMI and group II: cases with chronic coronary syndrome. All participants were subjected to ECG, Echocardiography, color Doppler, coronary angiography and laboratory investigations as differential CBC, cardiac enzymes, troponine, CK, CK-MB, CRP, urea, creatinine and random blood sugar. Patients who didn’t meet the criteria for invasive treatment, continued on medication and further noninvasive investigations done, starting from stress ECG, stress echocardiography, or CCTA. Results: There were insignificantly different between the two groups regarding age, gender and residency (p= 1.00). There was insignificant difference between the two groups regarding hypertension (p= 0.592), DM (p= 0.795) and dyslipidemia (p= 0.504). 7 (23.3%) cases were smokers in group I and 8(26.7%) patients were smokers in group II with insignificantly different between the two groups (p= 1.00). Conclusions: NLR is a powerful marker of myocardial damage in acute myocardial cases.
