ABSTRACT
Objective To study the value of deferred stent implantation in patients with high thrombus burden of acute ST-segment elevation myocardial infarction (STEMI). Methods Select 106 cases with a high thrombus burden within 12 hours of onset in patients with STEMI ,the infarct-related artery thrombus aspiration after antegrade flow of TIMI 2-3 and≤2 points of the thrombus aspiration(TS)patients were randomly divided into immediate stenting group(n = 43)and deferred stenting group(n = 40). Two groups of patients were compared with the myocardial blush grade(MBG),the incidence of slow-/no-reflow ,the incidence of compound endpoints in 6 months and the cardiac function after PCI for 6 months. Results After stenting,the MBG of deferred group was significantly higher than that of immediate group ,the incidence of slow-/no-reflow and the compound endpoints events within 6 months in deferred group was significantly lower than that in the immediate group. After PCI for 6 months,the improvement of LVEF in the deferred group was significantly higher than that in the immediate group, the left ventricular end diastolic dimension(LVEDD)in deferred group was significantly lower than that in immedi-ate group,and the differences were statistically significant(P < 0.05). Conclusions The high thrombus burden in patients with acute STEMI after thrombus aspiration ,deferred stent implantation can significantly reduce the rate of slow-/no-reflow ,improve myocardial perfusion ,reduce the incidence of compound endpoints events ,im-prove cardiac function in patients.
