Objective: To assess the performance of ten electrocardiographic (ECG) parameters regarding the prediction of left ventricular systolic dysfunction (LVSD) after a first ST-segment-elevation myocardial infarction (STEMI). Methods: We analyzed 249 patients (74.7% males) treated with primary percutaneous coronary intervention (PCI) included into a single-center cohort study. We sought associations between baseline and post-PCI ECG parameters and the presence of LVSD (defined as left ventricular ejection fraction [LVEF] ≤ 40% on echocardiography) 6 months after STEMI. Results: Patients presenting with LVSD (n = 52) had significantly higher values of heart rate, number of leads with ST-segment elevation and pathological Q-waves, as well as total and maximal ST-segment elevation at baseline and directly after PCI compared with patients without LVSD. They also showed a significantly higher prevalence of anterior STEMI and considerably wider QRS complex after PCI, while QRS duration measurement at baseline showed no significant difference. Additionally, patients presenting with LVSD after 6 months showed markedly more severe ischemia on admission, as assessed with the Sclarovsky-Birnbaum ischemia score, smaller reciprocal ST-segment depression at baseline and less profound ST-segment resolution post PCI. In multivariate regression analysis adjusted for demographic, clinical, biochemical and angiographic variables, anterior location of STEMI (OR 17.78; 95% CI 6.45–48.96; p < 0.001), post-PCI QRS duration (OR 1.56; 95% CI 1.22–2.00; p < 0.001) expressed per increments of 10 ms and impaired post-PCI flow in the infarct-related artery (IRA; TIMI 3 vs. <3; OR 0.14; 95% CI 0.04–0.46; p = 0.001) were identified as independent predictors of LVSD (Nagelkerke’s pseudo R2 for the logistic regression model = 0.462). Similarly, in multiple regression analysis, anterior location of STEMI, wider post-PCI QRS, higher baseline number of pathological Q-waves and a higher baseline Sclarovsky-Birnbaum ischemia score, together with impaired post-PCI flow in the IRA, higher values of body mass index and glucose concentration on admission were independently associated with lower values of LVEF at 6 months (corrected R2 = 0.448; p < 0.00001). Conclusions: According to our study, baseline and post-PCI ECG parameters are of modest value for the prediction of LVSD occurrence 6 months after a first STEMI.

Objective: to study the effect of prehospital thrombolysis on left ventricular systolic dysfunction in patients with acute ST-segment elevation coronary syndrome.Material and methods: The study included 70 patients with acute coronary syndrome with ST-segment elevation. Patients were randomized into two groups: control (group A) - 35 patients receiving standard therapy, and hospital TLT. Group B included 35 patients who underwent standard therapy and prehospital TLT. All 70 patients underwent echocardiography 1 day after myocardial revascularization and 3 months later.Results: the use of early myocardial reperfusion in patients with STEMI had a positive effect on central hemodynamics, reduced the development of LV volume overload, as a result of which end-diastolic and systolic volumes did not change during 3 months of follow-up. LVEF grew in both groups, and its growth was more pronounced in group B.Conclusion: timely prehospital reperfusion reduces the severity of myocardial damage and thus prevents the development of severe systolic myocardial dysfunction LV.
