Abstract:
OBJECTIVE:To retrospectively evaluate the efficacy of stent-delayed implantation in patients with acute myocardial infarction (AMI) with high thrombus burden after thrombus extraction was performed.
METHODS:Of 186 consecutive AMI patients, 56 were included according to thrombus score(TS)>or=2, and then were divided into 2 groups based on the thrombus score after thrombus extraction was executed: the stent-direct implantation group (TS=0 or 1)and the stent-delayed implantation group (TS>or=2) even if 3 times thrombus extraction were given. Thrombolysis in myocardial infarction(TIMI)flow grade and TIMI myocardial perfusion (TMP) were used to assess the coronary artery flow and myocardial perfusion,respectively.
RESULTS:TIMI score in the stent-direct implantation group was lower than that in the stent-delayed implantation group. There was no significant difference(P=0.07). TMP score in the stent-direct implantation group was significantly lower than that in the stent-delayed implantation group (P<0.05).
CONCLUSION:Stent-delayed implantation can remarkably improve myocardial perfusion in AMI patients with high thrombus burden after thrombus extraction and intensive anti-thrombosis therapy is administrated.
