Introduction: Cardiovascular Disease (CVD) is the leading cause of death and disability globally. The Thrombolysis in Myocardial Infarction (TIMI) score is calculated to assess the risk outcome among myocardial infarction patients. Researchers found that diabetic patients with myocardial infarction have relatively unfavourable outcomes when compared to myocardial infarction patients without diabetes.
Aim: To evaluate Glycated Haemoglobin (HbA1c) levels, the TIMI score in Acute Myocardial Infarction (AMI) patients and compare them between ST Elevation Myocardial Infarction (STEMI) and non STEMI (NSTEMI) patients.
Materials and Methods: This cross-sectional study was conducted at the Intensive Care Unit (ICU) of the Department of Cardiology at SRM Medical College Hospital and Research Centre, Kattankulathur, Chengalpattu, Tamil Nadu, India, from July 2022 to June 2023. A total of 100 myocardial infarction patients were included and divided into two groups based on Electrocardiogram (ECG) findings and Creatine Phosphokinase-MB (CK-MB) values, with 50 STEMI and 50 NSTEMI. Patients blood samples were evaluated for HbA1c, total cholesterol, Triglycerides (TGL), High-density Lipoprotein Cholesterol (HDL-C), Low-density Lipoprotein Cholesterol (LDL-C), Very High-density Lipoprotein Cholesterol (VLDL-C), and CK-MB parameters. The TIMI score was calculated to evaluate the risk of developing complications among myocardial infarction patients. Pearson’s correlation was used to correlate biochemical parameters with the TIMI score.
Results: A total of 100 myocardial infarction patients were analysed in the present study, with 50 being STEMI (mean HbA1c%: 8.0±0.2.8) and 50 being NSTEMI (mean HbA1c%: 7.2±2.0) with a p-value of <0.01*, a high TIMI score in STEMI patients (means 5.38±2.76) and 50 NSTEMI (mean 3.24±1.20) with a p-value of <0.0001*. Also, HbA1c was strongly positively correlated with the TIMI score in both the STEMI and NSTEMI groups, with r-value of 0.6 (p=0.0001*) and 0.7 (p=0.0001*), respectively. CK-MB was correlated with the TIMI score in both STEMI and NSTEMI, with r-value of 0.308 (0.03) and 0.375 (0.007). There was no correlation between the TIMI score and the lipid profile.
Conclusion: The study concluded that HbA1c, along with the TIMI score, is a significant predictor of risk outcome in AMI patients.
