We carried out prehospital thrombolytic therapy (TLT) with tenecteplase in 24 patients with ST-elevation myocardial infarction (MI) at the background of standard concomitant therapy with unfractionated heparin, aspirin, and clopidogrel and analyzed clinical course of MI, ECG dynamics, systolic left ventricular function according to echocardiography. In 20 patients coronary angiography was performed after TLT. Mean symptom - needle time was 113 min. In 14 patients (58%) TLT was carried out within 2 hours after appearance of symptoms. In 19 patients the course of disease was uncomplicated. Electrocardiographic criteria of effective reperfusion were registered in 14 patients (58%), angiographic criteria - in 13 patients (65% of subjected to angiography). Percutaneous intervention was performed in 18 patients (75%). Systolic left ventricular dysfunction was revealed in 5 patients (21%), aborted MI - in 4 patients. Significant correlation was found between aborted MI (r=0,38, p=0,034) and uncomplicated MI (r=0,40, p=0,027) and performance of TLT during first 2 hours. There were no hemorrhagic complications. Results of the study evidence for high efficacy of prehospital thrombolysis with tenecteplase and real possibility of its use under conditions of existing system of organization of urgent cardiological aid. |
