Clinical Observation And Research Of Reperfusion Arthythmia In Patients With Acuet Myo-Cardial Infarction During Emergency Percutaneous Coronary Interventions

Objectives：To more investigate clinical features of reperfusion arrhythmia(RA)in acute myocardial infarction(AMI) patients during emergencypercutaneous coronary interventions(PCI).Methods：Retrospective analysis the Clinical datas of125AMI patients whichreceived emergency PCI from October2010to October2011ofCardiology Department of Second Hospital of Jilin University. Observingthe relationship between RA and the opening time of the infarct-relatedartery（IRA）、the stenosis degree(partial or total) of IRA as well as theinfarct size.Results：RA occurs in85patients of the125cases(accounting for68%).TheRA incidence of the Patients with open coronary artery within6h isobviously higher than that of6~12h opened (77.50%vs51.11%P＜0.05); Patients with total occlusion of coronary artery has a more higherRA Incidence than patients with partial occlusion (75.58%vs51.28%P＜0.05); The RA incidence between patients with small myocardialinfarction and patienis with big myocardial infarction has no obviouslydifference (55.00%vs61.53%P＞0.05).Conclusion1、The RA incidence of AMI patients which received emergency PCIhas certain relationship with the opening time of the IRA. Ischemia timeis very short or very long, are not prone to reperfusion arrhythmia.2、The RA incidence of AMI patients which received emergency PCI has relationship with the stenosis degree(partial or total) of IRA. Partialocclusion of IRA is not easy to reperfusion arrhythmia. Partial occlusionof IRA is a process of ischemia，The myocardial cells IPC.3、The RA incidence of AMI patients which received emergency PCIhas relationship with Infarct size. The RA incidence between patientswith small myocardial infarction and patienis with big myocardialinfarction has no obviously difference.
