Changes of electrocardiographic and echocardiographic data after early and late mechanical recanalization of infarct-related artery with and without stent implantation
Abstract
Material and methods. A total of 248 consecutive patients were divided into these groups: early angioplasty (≤24 hours) without stents (n=114) or with stents (n=6) and later (>24 hours) angioplasty without stents (n=114) or with stents (n=14). The changes in QRS score and echocardiographic left ventricular ejection fraction during the hospital and 3-month follow-up periods were compared between the groups.
Results. QRS score did not increase in a hospital in early or late angioplasty with stents groups, while in the groups without stents especially of early angioplasty increased (2.6±2.5 vs. 3.6±2.4, P=0.001). Left ventricular ejection fraction increased after 3 months only in early angioplasty groups especially with stents (30.0±3.5 vs. 38.4±5.2, P=0.008), but there were no significant differences between the QRS score at discharge and after 3 months (5.4±4.3 vs. 5.0±1.9).
Conclusions. Myocardial injury did not increase in a hospital in the cases of early or late angioplasty with stents, while in the cases without stents increased. Left ventricular ejection fraction increased after 3 months only in the cases of early angioplasty especially with the stent implantation, but the QRS score showed no differences, so the QRS score may be not predictive of improvement in ejection fraction at follow-up.
