Comparison of the Selvester QRS scoring system and GRACE scale in the evaluation of the risk of sub-acute myocardial infarction

Aim. To compare the performance of Selvester and GRACE scale in evaluating the risk prognosis of sub-acute myocardial infarction. Objectives. 1. To predict in-hospital mortality of sub-acute STEMI by Selvester QRS scoring system. 2. To predict in-hospital mortality of sub-acute STEMI by GRACE scale. 3. Comparison of Selvester QRS scoring system and GRACE scale in predicting in-hospital mortality of sub-acute STEMI. Material and Methods. Consecutive 48 patients (male 33.3 %, female 66.7 %) with the age of 80.31 ± 7.47 years were investigated in this study. The inclusion criteria were: confirmed MI by troponin and ECG criteria of sub-acute MI at admission to a hospital: still elevated ST segment >= 1 mV with inverted T wave at least 1 mV. Exclusion criteria were only the following: ventricular pacemaker and intraventricular conduction defects. The patients’ ECG, taken at the arrival to the hospital, were considered to predict the risk of in-hospital mortality by Selvester QRS score and clinical findings including ECG changes were used to interpret the high-risk of in-hospital mortality by GRACE score. The data analysis was performed by using the package SPPS 22.0. McNemar’s test was used to compare the scores. Results. Even high GRACE score > 154 points and Selvester score > 6 did not predict the death (significant difference in comparison with actual in-hospital mortality was found for both scores, p = 0.000 and p = 0.001, respectively). But Selvester score > 8 was predicting the death (there was no difference in comparison with actual in-hospital mortality, p = 0.092) with the accuracy 72.9%. Conclusion. Selvester score > 8 was predicting the in-hospital mortality in cases of sub-acute STEMI, even high GRACE score did not predict.

Conclusion. Selvester score > 8 was predicting the in-hospital mortality in cases of sub-acute STEMI, even high GRACE score did not predict.
