Abstrakt | The aim of the study was to assess, in patients with acute myocardial infarction (AMI), relation between electrocardiographically determined duration of electrical systole on one side and left ventricular regional wall motion abnormality score (WMS) and success of thrombolytic therapy on the other side. Sixty-two consecutive patients with 4 days old AMI were included. Among them were 38 males and 24 females, aged 62.5 +- 9.9 years; 28 had anterior wall AMI and 34 had inferior wall AMI. Thirty-one received thrombolytic treatment, which was presumably successful in 22. QT interval from a high resolution (HR) ECG, recorded in three bipolar precordial orthogonal Frank leads (QTc xyz), as well as the longest QT from those standard 12 ECG leads, which corresponded to infarct localisation (QTcs), corrected by Bazett's formula, were considered for the study. WMS was evaluated echocardiographically. We found a significant correlation between WMS and QTc interval duration; the correlation was stronger in patients with anterior AMI (r=0.9, p less th. 0.001) than in those with inferior AMI (r=0.66, p less th. 0.001). It was stronger ifwe used QTc xyz instead of QTcs and if patients with successful thrombolytic treatment were excluded from the calculation. WMS and QTc values were significantly lower in patients with successful thrombolytic treatment compared to those with unsuccessful thrombolysis (p less th. 0.003 and p less th. 0.002, respectively). In patients with anterior AMI, QTc interval duration might represent an addition al marker of left ventricular systolic dysfunction. It could also be used as an additional non-invasive criterion for coronary artery reperfusion in patients with AMI. | |
