A comparative study on the effect of coronary angioplasty on left ventricular function in post myocardial infarction among patients with and without type-2 diabetes mellitus

Background and objectives. Coronary angioplasty is a common intervention for improving cardiac function postmyocardial infarction. However, the impact of this procedure in patients with type-2 diabetes mellitus (T2DM) compared to those without diabetes remains less understood. Material and methods. This study included 50 patients who underwent coronary angioplasty post-myocardial infarction. Patients were divided into two groups based on the presence (Group A) or absence (Group B) of T2DM, with 6 patients in each group. We assessed left ventricular function using echocardiography, focusing on ejection fraction and wall motion score, at baseline, and at 1, 3, and 6 months post-angioplasty. Additional data on clinical outcomes, functional status, cardiac biomarkers, medication use, comorbid condition management, and hemodynamic measurements were also collected. Results. Both groups showed improvement in left ventricular function post-angioplasty, with no significant difference in ejection fraction and wall motion score between the two groups at each follow-up. Clinical outcomes, functional status, and biomarker levels were comparable between groups. Medication compliance was high in both groups. The control of comorbid conditions and hemodynamic stability post-angioplasty were similarly maintained in both diabetic and nondiabetic patients. Conclusion. Coronary angioplasty positively impacts left ventricular function in post-myocardial infarction patients, irrespective of the presence of T2DM. Both diabetic and non-diabetic patients demonstrated similar improvements in cardiac function and overall clinical outcomes, suggesting that angioplasty is an effective intervention for post-myocardial infarction patients regardless of their diabetes status. Further studies with larger sample sizes are recommended to validate these findings.
