Pre-hospital electrocardiographic severity and acuteness scores predict left ventricular function in patients with ST elevation myocardial infarction

About QRS prolongation, distortion and the acuteness score

“…None of the combination groups predicted left ventricular ejection fraction. Wall motion index score was the worst in patients with grade III and "late" ischemia and tended to be the least impaired in patients with grade III and "acute" ischemia [14]. Their results are in accordance with the study of Schoos et al [33].…”

“…1 with anterior ST elevation in the paper by Fakhri et al [14]. Thus the question remains whether the differences shown between the groups in the studies of Fakhri et al [14] are actually related solely to the presence of abnormal Q waves [37,39]. We are not aware of any study comparing the presence of Q waves to the more complicated calculated A-W acuteness score.…”

“…It seems that there is no clear difference in the T-wave morphology or amplitude among the ECG samples of Fig. 1 with anterior ST elevation in the paper by Fakhri et al [14]. Thus the question remains whether the differences shown between the groups in the studies of Fakhri et al [14] are actually related solely to the presence of abnormal Q waves [37,39].…”

“…Two papers included the "Sclarovsky-Birnbaum" score [14,15] and two the Anderson-Wilkins (A-W) acuteness score [14,16]. The Sclarovsky-Birnbaum score, originally described by Sclarovsky in 1990 [17], was first tested as a predictor of clinical outcomes in patients with acute myocardial infarction by Birnbaum and Sclarovsky [18][19][20].…”

“…Fakhri et al assessed the predictive value of both the Sclarovsky-Birnbaum score and the A-W acuteness score in the prehospital ECG of 273 STEMI patients on left ventricular function [assessed by echo (global longitudinal strain, left ventricular ejection fraction and wall motion index score) within 48 h after pPCI] [14]. They report that patients with grade III ischemia and "late" ischemia had the most impaired global longitudinal stain (GLS).…”
