    This study was conducted to ascertain whether the modified Selvester QRS scoring system would be able to predict the clearance of ST segment elevation in patients undergoing streptokinase-based thrombolytic treatment for acute myocardial infarction. Methods This study was conducted in a hospital setting and involved 61 patients aged between 30 and 80 years who were diagnosed with a new onset acute ST elevation myocardial infarction receiving thrombolytic therapy with streptokinase. Based on 37 criteria and a modified Selvester scoring method, the QRS score was determined, yielding a total of 29 points. A QRS score greater than four was regarded as non-resolution. Additionally, patients were divided into non-resolution groups (STR < 50% of STE1) and resolution groups (STR ≥ 50% of STE1). The SPSS 24 program was used to carry out the statistical analysis. Results Patients with diabetes exhibited high QRS scores, but there was no relationship between them and the ST resolution. There was a substantial association between the QRS score, ST resolution and cardiac failure. The QRS score was higher and the incidence of ST non-resolution was higher in patients with heart failure. In this investigation, there was no significance for patients with dyslipidemia or MI. The resolution group's QRS score was lower than that of the non-resolution group. A noteworthy inverse relationship was observed between the STR and QRS scores. Additionally, there was a negative connection between QRS score and ejection percentage. Conclusion When patients with STEMI are receiving thrombolytic therapy, the QRS score accurately predicts the resolution of the ST segment. Patients are more likely to experience non-resolution of the ST segment if their QRS score is greater than 4.
