Admission Plasma Glucose as In-Hospital Outcome Predictor in First Attack of Non-ST Segment Elevation Myocardial Infarction in Non Diabetic Patient.

| Abstract |
Coronary artery disease is the leading cause of death and disability globally. The presentation of Non-ST segment elevation myocardial infarction (NSTEMI) is heterogeneous, with different risk levels in terms of death, infarction and recurrence of infarction. Current evidence suggests that plasma glucose level or hyperglycemia is a mediator of worse prognosis of MI. The objective of the study was to correlate on admission plasma glucose level in non-diabetic patient with in-hospital outcome of patients after first attack of NSTEMI. This prospective analytical study was conducted among purposively selected 280 patients with NSTEMI admitted in coronary care unit of Mymensingh Medical College Hospital during the period of June 2016 to May 2017. Data were collected from the informant by face to face interview, clinical examination and investigations using a pretested semi-structured case record form. Data were analyzed by SPSS. Patients were categorized into two groups; Group A: NSTEMI with admission plasma glucose level below 7.8mmol/l, (n=150, Male-110, Female-40). Group B: NSTEMI with admission plasma glucose level ≥7.8mmol/l, (n=130, Male-95, Female-35). Group B (n=130) is divided into two subgroups. Subgroup-I: NSTEMI with Hyperglycemia (7.8-9.3mmol/l), n = 67 (male 44, female 23), Subgroup-II: NSTEMI with Hyperglycemia (≥9.4mmol/l), n = 63 (male 51, female 12). All Patients were non diabetic excluded by HbA₁c. The mean left ventricular ejection fraction (LVEF) of Group B, Subgroup-II was significantly less than that of Subgroup-I (p<0.05). Correlation between LVEF levels and on admission plasma glucose level showed statistically significant moderate negative correlation, suggesting that the higher was the level of on admission plasma glucose level; the lower was the LV ejection fraction level in first attack of NSTEMI patients. Correlation coefficient between Troponin-I and plasma glucose level on admission of the study population (r=0.030) suggesting that the higher was the level of admission plasma glucose level the higher was the Troponin-I level in first attack of NSTEMI patients. The more was the plasma glucose level, less was LVEF, more was the heart failure and prolonged hospital stay. The study showed a strong predictor of adverse in-hospital outcome in the various levels of plasma glucose and NSTEMI. There was association between the concentration of the plasma glucose and the extent, severity of disease in the means of mean LVEF, the rate of heart failure and duration of hospital stay. The importance of this finding is even clear that RBS is a standard, valuable diagnostic tool for evaluation of severity and prediction of outcome of patients with NSTEMI.
