Comparative Outcome Study between Resolved and Unresolved St Segment in St Segment Elevation Acutemyocardial Infarction (STEMI) after Thrombolytic Therapy

Abstract

Background: To study the comparative outcome between resolved an unresolved ST segment in ST Segment Elevation Acute Myocardial Infarction (STEMI), after thrombolytic therapy. Method: A study was carried out on patients admitted with 1st episode of ST elevated myocardial infarction in MICU of a tertiary health care center of a teaching hospital. On admission detailed history was taken and a complete clinical examination was done. Thrombolysis was done using streptokinase, 2D ECHOs were performed before and after thrombolytic therapy. Result: Most of the study population in both the group (Unresolved STEMI and Successful thrombolysis), belonged to the age group of 41 to 50 years. Co-morbidities like hypertension were present in 83% of Unresolved STEMI and 53% of Resolved STEMI. Comorbidities like diabetes were present in 66.7% of Unresolved STEMI and 52.6% of Resolved STEMI. RWMA on 2D-Echo before thrombolysis was present in 58.3% of Unresolved STEMI and 47.4% of Resolved STEMI. RWMA on 2D-Echo after thrombolysis was present in 66.7% of Unresolved STEMI and 18.5% of Resolved STEMI. Conclusion: Symptom to needle time is an important predictor of whether thrombolysis will be successful or not in acute myocardial infarction patients. Hence it is important to educate the public about prompt recognition of symptoms and seeking medical help urgently. As the rate of unsuccessful thrombolysis is higher in patients with old age, diabetes, hypertension and dyslipidemia, such patients should be monitored and treated aggressively.
