Study of Serum Troponin-I Level in Non-diabetic Hyperglycemic ST Elevation Myocardial Infarction Patients

The most common cause of premature death in developing countries like Bangladesh is ischaemic heart disease. Cardiac troponin-I (cTnI) is 100 percent tissue specific for the myocardium which has been shown to be a very sensitive and specific biomarker for acute myocardial infarction. As acute myocardial infarction is a stressful condition so, plasma glucose level may also increase in this condition which is stress hyperglycemia and also plasma glucose level may be used for prediction of outcome as it is a cheap and easy available test. The aim of the study is to investigate the impact of the elevation of troponin-I level with plasma glucose level of non-diabetic patients in ST-elevation myocardial infarction. This study which was comparative type of analytical and cross- sectional study carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2021 to December 2021. Data was collected from Cardiology Department of Mymensingh Medical College Hospital, Mymensingh. A total number of 70 subjects participated in this study and were grouped as normoglycemic ST elevation myocardial infarction- Control group (Group I) and non-diabetic hyperglycemic ST elevation myocardial infarction- Study group (Group II). The results were calculated and analyzed by using SPSS. Serum troponin-I was measured by Fluorescence Immunoassay (FIA) and plasma glucose estimated by GOD-PAP method. Data were expressed in mean±SD and statistical significance of difference among the groups were calculated by unpaired Student’s ‘t’ test. The correlation between different parameter was done by Pearson’s correlation coefficient test. In this study, the result suggests that there is significant positive association between serum troponin-I and plasma glucose level in study group (hyperglycemic non-diabetic STEMI) in comparison to control group (normoglycemic STEMI). So, by this study we recommend that routine estimation of these parameters is important for prevention of complications related to acute myocardial infarction.
