Diabetes Mellitus and Myocardial Infarction: Correlation Among Based on a Study in a Tertiary Care Centre, India

Background: Diabetics have a higher mortality rate during the acute phase of a myocardial infarction (MI) and a higher morbidity rate during the post-infarction period. The purpose of this study was to determine the prevalence of diabetes as a risk factor for acute myocardial infarction.

Methods: For each patient, detailed demographic information such as age, gender, weight, BMI, blood pressure, smoking and alcohol history, and previous clinical and medical history were recorded. Blood was drawn from the patients to determine random blood glucose levels and HbA1c levels. Fasting blood glucose levels were measured on the second and fifth days of admission.

Results: The average age of the patients was roughly 66 years, and 63.5 percent were males and just 36.5 percent were females. The majority of MI patients admitted to hospitals were obese or overweight, with high cholesterol and triglyceride levels. 59 (56.7%) of the 104 patients did not have diabetes, while 29 (27.9%) were diabetics. During their hospitalisation, 11 (10.6 percent) of them were diagnosed as diabetic.

Conclusions: Chronic and acute hyperglycemia associated with acute coronary syndromes, most notably acute myocardial infarction, is an independent and determinant factor in outcome for patients with and without diabetes mellitus.
