[The use of tirofiban in invasive treatment of patients with non-ST-elevation acute coronary syndrome].
The study assessed 123 patients with non-ST-elevation acute coronary syndrome who were randomized into two groups: percutaneous coronary intervention (PCI) (62 patients) and PCI against background of tirofiban injection (61 patients). The results of the study were estimated during the early (up to 30 days) and the late (up to 180 days) follow-up. It was stated that the use of tirofiban has led to the increase of minor bleedings (11% versus 4.8%, p<0.05), but the total amount of bleedings between the groups did not differ: 19.7% in the tirofiban group versus 14.5% in group I. The use of tirofiban has led to the significant growth of the LV ejection fraction (5+/-4% versus 2+/-3%, p<0.05) and increment of the LV wall motion index (0.28+/-0.18 versus 0.12+/-0.21, p<0.001). There was no difference in the frequency of the early events: 9.6% versus 8.2% in the groups without and with the use of tirofiban accordingly (p<0.05). The use of tirofiban was associated with the decrease in the frequency of all events during the first 180 days after PCI: 30.7% in group I and 13.1% in the tirofiban group (p<0.005). Absence the main cardiovascular complications according to Kaplan-Meier method for all patients amounted to 77+/-6%, in the group of the patients who received tirofiban 88+/-6%, and 64+/-8% in the group of the patients who did not receive tirofiban (p=0.009). Thereby, the use of tirofiban in the treatment of the patients with non-ST-elevation acute coronary syndrome does not lead to the increase in the frequency and severity of bleedings. At the same time, the use of tirofiban in the treatment of the patients with acute coronary syndrome has a significant influence on the growth of the LV wall motion index and the LV ejection fraction by increasing them. Under these conditions when using tirofiban in the late period the frequency of all events during PCI is 2.3 times lower compared to the patients who did not receive tirofiban.
