Selvester QRS Score to Quantify the Extent of Myocardial Infarction in Patients with Anterior Myocardial Infarction and Its Correlation with Left Ventricular Function

Background: The degree of left ventricle myocardial scarring in individuals with anterior myocardial infarction (MI) has a poor prognosis because it leads to worsening of left ventricular (LV) systolic and diastolic performance. Objectives: To assess the Selvester score’s applicability in quantifying the extent of myocardial infarction, and its relationship with systolic and diastolic LV function. Materials and Methods: A total of 50 individuals with anterior myocardial infarction participated in this cross-sectional study. The Selvester QRS score was calculated from the quantitative analysis of the 12-lead electrocardiogram (ECG) to determine the extent of the LV infarct. Two and three dimensional echocardiographic (2D and 3D-Echo) assessments were done for all patients to measure the left ventricular systolic and diastolic functioning. Results: The Selvester scores of all participants varied from 1 to 15, with a mean equal to 6.1 ± 3.51 points, and the extent of the LV infarct ranged from 3% to 45%, with a mean of 20% ± 0.09389. Correlation studies of LV infarct size with LV diastolic and systolic parameters revealed a statistically significant positive correlation with E / e ′ ( P = 0.004), a statistically significant negative correlation with 2,3D-ejection fraction ( P = 0.004, 0.000, respectively), and a statistically significant positive correlation with 3D-sphericity index ( P = 0.04). Conclusion: Selvester scoring can be used in the assessment of infarct size in anterior MI patients, and could additionally reflect the degree of systolic and diastolic LV dysfunction from the significant correlation results of this study, so it could be considered a part of the routine evaluation of ECGs in these patients.
