The Clinical Efficacy Analysis Of Emergency PCI In Myocardial Infarction

Objective:This study is to evaluate the clinical efficacy of treatment with or without emergency percutaneous coronary intervention (EPCI) in acute myocardial infarction (AMI). Methods:145 AMI patients were enrolled and divided into 2 groups: A, EPCI using balloon angioplasty, atherectomy or intracoronary stenting was performed in 58 AMI patients. B, conventional therapy alone or plus thrombolysis was performed in 87 AMI patients. Patient follow-up 12 months was available. Then, clinical index difference of this procedure include average hospital days, left ventricular ejection fraction, the incidence rate of postinfarction angina, reperfusion arrhythmias, congestive heart failure and cardiac death are examined using statistic analysis. Results:(1) There were no significant differences in the general clinical data between group A and B(P>0.05). (2) For average hospital days, it is obviously decreasing in group A compared with group B (P<0.05). The incidence rate of postinfarction angina, congestive heart failure and cardiac death of group A is obviously lower than group B. The reperfusion arrhythmias and left ventricular ejection fraction are obviously increased in group A compared with that in group B (P<0.05). (3) Compared with the non-EPCI, EPCI resulted in the infarcttion relative artery recanaliztioning in time. Conclusions:The prognosis of the AMI is closely correlated with the therapy to be choiced. The EPCI obviously improved heart function, decreased the incidence rate of postinfarction angina, cardiac death and average hospital days. So, this suggested that AMI patients may get much clinical benefit from EPCI treatment.
