Therapeutic effect of coronary artery stent implantation on acute myocardial infarction / 心血管康复医学杂志

ABSTRACT

Objective:To explore therapeutic effect of coronary artery stent implantation (CASI) on acute myocardial infarction (AMI ) . Methods:According to voluntary choice , a total of 89 AMI patients were divided into drug thrombolysis group (n=44 ,received intravenous drug thrombolytic therapy) and CASI group (n=45 ,received CA‐SI treatment) .Therapeutic effect ,symptom relieving time after treatment ,hospitalization duration and left ventric‐ular ejection fraction (LVEF) were compared between two groups ;all patients were followed up for 1~3 years ,in‐cidence of death and cardiac events ,including re -occlusion ,severe heart failure and severe arrhythmias were ob‐served and compared between two groups .Results:Success rate of reperfusion of CASI group was significantly high‐er than that of drug thrombolysis group (91.11% vs .68.18% ) , P<0.05. Compared with drug thrombolysis group , there were significant rise in LVEF [(42.58 ± 13.10)% vs .(57.32 ± 18.61)% ] ,and significant reductions in symp‐tom relieving time [ (8.09 ± 8.31) h vs .(3.75 ± 3.58) h] and hospitalization duration [ (19.84 ± 8.15) d vs . (13.01 ± 5.40) d] in CASI group , P<0.01 all .During follow -up ,compared with drug thrombolysis group ,there were significant reductions in incidence rates of severe heart failure (18.18% vs .4.44% ) ,severe arrhythmias (22.73% vs .6.67% ) and death (6.82% vs .2.22% ) in CASI group , P<0.05 or <0.01.Conclusion:Coronary ar‐tery stent implantation possesses significant therapeutic effect on acute myocardial infarction ,it can significantly shorten hospitalization duration ,and its incidence rate of adverse cardiac events is significantly lower than that of drug thrombolysis ,which is worth extending .
