St сегмент элевацияли ўткир миокард инфарктида шифохонагача тизимли тромболизиснинг чап қоринча систолик дисфункциясига таъсири

Abstract

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.
