Effects of emergent percutaneous coronary intervention on the prognosis of patints with cardiac arrest and cardiopulmonary resuscitation after acute myocardial infarction / 中华急诊医学杂志

ABSTRACT

Objective To investigate effects of emergent percutaneous coronary intervention(EPCI)on the prognosis of patients with cardiac arrest(CA)and cardiopulmonary resuscitation after acute myocardial infarction(AMI).Methods Thirty-two patients with CA and carcliopulmonary resuscitation after AMI were retrospectively reviewed and divided into EPCI group(n=12)and eonservative treatment group(n=20).EPCI was used during or after primary eardiopulmonary resuscitation in EPCI group but not in conservative treatment group.Mortality and occurrence rates of severe arrhythmia,of heart failure,of cardiac shock and of severe bleeding in hospital were compared between the two groups.Results The mortality in hospital was 17% in EPCI group and 70% in conservative treatment group,respectively(P＜0.001).Heart failure was developed in 3 patients from EPCI group and 16 patients from conservative treatment group,respectively(P＜0.01).There was no significant difference in severe arrhythmia,cardiac shock and severe bleeding between two groups(P＞0.05).Logistic regression showed that EPCI decreased mortality but the prolonged cardiopulmonary resuscitation(＞20 min)increased the mortality.Conclusion Early EPCI might improve the prognosis of patients with cardiac arrest and cardiopulmonary resuscitation after acute myocardial infarction.
