[DELAYED CORONARY SURGERY FOR THE TREATMENT OF ACUTE MYOCARDIAL INFARCTION WITH ELEVATED ST SEGMENT]

To develop algorithms of reperfusion therapy (RT) based on the assessment of the initial risk of death determining the priority use of delayed transdermal coronary surgery (TCS) unavailable in the early period. We compared effectiveness of different strategies for the treatment of 1245 patients with acute myocardial infarction (MI) and elevated ST segment in 2003-2007 including various TCS modalities at recommended time (n = 88), delayed TCS within 24-72 hr after the onset of MI (n = 194), thrombolytic therapy without subsequent TCS (n = 275), and conservative therapy (N = 688). The general and cardiovascular lethality was evaluated among 474 patients 5 years after discharge. The results suggest that unavailability of TCS in recommended time in case of enhanced risk of death does not exclude the possibility of its delayed application. TCS 24-72 hr after the onset of MI prevents complications and the fatal outcome the frequency of which remains high remains high not only in the early but also in the late post-infarction period. Delayed TCS can be effectively used to treat patients in case of their late admission or referral from other hospitals where X-ray endovascular methods for the treatment of acute MI are not used.
