: Individuals who are at risk of CVD( cardio vascular disease) may also have comorbidities like elevated blood pressure, glucose levels, dyslipidemia, obesity etc. Identifying those high risk individuals helps in prevention of premature deaths. So there might be an association between elevated blood glucose levels and overall mortality rate in MI (Myocardial Infarction ) patients. So the present study is undertaken to estimate the severity of myocardial infraction with estimated average blood glucose levels. This is an observational study done on 50 patients divided into 2 groups, group 1-patients having diabetes, group2- patients without diabetes of age >18 years who admitted in VMMC, Karaikal coastal area hospital with complaints of STEMI, NSTEMI and unstable angina for a duration of 18 months from July 2021 to December 2022. After admission, detailed history, blood sugar levels, ECG,2D-Echo, were estimated in the patients and it is correlated with the severity of the patient by comparing with GRACE 2.0 scoring. We observed that there is significant relation of GRBS,FBS,PPBS,HBA1C levels between study group and control group with MI. eAG (estimated average glucose )of patients with diabetes to non-diabetic patients it shows that the severity of myocardial infraction is more in diabetics compared to non-diabetics eAG to risk and grace 2.0 scoring in general is statistically insignificant. So further studies are needed to be done prove its association.
