Analysis Of The Relative Factors About Reperfusion Arrhythmia During PCI In Patients With Acute Myocardial Infarction

Objective:Analysis of the relative factors about reperfusion arrhythmia(RA) during percutaneous coronary intervention(PCI) in 12 hours of patients with acute myocardial infarction (AMI).To conclude the mechanism ,relative factors,the type and the features of RA, to conclude how to prevent it in order to increase the quality and decrease the mortality of life .Methods:Collect the materials of AMI who underwent PCI and opened the infarct related artery (IRA) in 12 hours of Cardiovascular Center in the first hospital of Jilin university from January 2008 to October 2009. The patients who underwent PCI were choosed according to the standards by International society of cardiology and WHO ischemic heart disease. Reperfusion arrythmia (RA) occurred in 127 out of 240 patients. To conclude the type of RA, analysis of the relative factors about it during percutaneous coronary intervention (PCI). Establish the database about reperfusion arrhythmia during PCI in patients with acute myocardial infarction .The statistical software SPSS 16.0 for Windows was used for all the statistical analyses.Results:1.Compare reperfusion arrhythmia ( RA ) group with no reper- fusion arrhythmia(RA)group, smoking[56(44.1%)vs.52(46.0%), P=0.765],hypertension[58(45.7%)vs.59(52.2%),P=0.311] ,diabetes [36(28.3%)vs.32 ( 28.3% ) ,P=0.996],hyperlipidemia [62 ( 48.8% ) vs.61(54.0%),P=0.424],seriou congestive heart failure(Killip class≥Ⅱ) (Killip class≥Ⅱ)[12(9.4%) vs.17(15.0%),P=0.184] did not influence the RA.2.With the situations such as myocardial ischemia before AMI[41(32.3%)vs.71(62.8%),P<0.001],TIMI flow grade 0 on initial angiogram[86(67.7%)vs.42(37.2%),P<0.001], Attack-to-Balloon Time≤6 hours[82(55.1%)vs.45(49.5%),P<0.001], more branches involved[30(23.6%)vs.45 ( 39.8% ) ,P < 0.001], left trunk involved[5 ( 3.9% ) vs.16(14.2%),P=0.005], occlusion of LAD[53(41.7%)vs.80(70.8%),P<0.001],occlusion of LCX[26(20.5%)vs.7(6.2%),P=0.001], and occlusion of RCA [70(55.1%)vs.35(31.0%),P<0.001],RA was significantly higher.3.Slow RA were significantly higher in occlusion of RCA[56(74.7%)vs.14(26.9%),P<0.001], rapid RA were significantly higher in occlusion of LAD[15(20.0%)vs.38(73.1%),P<0.001=. Conclusion:1.RA was usually occurred in AMI during PCI.2.RA was tent to occur in the situations such as TIMI flow grade 0 on initial angiogram, Attack-to-Balloon Time≤6 hours, more branches involved, left trunk involved, occlusion of LAD,occlusion of LCX, and occlusion of RCA .3.RA was not tent to occur in the patients with myocardial ischemia before AMI.4.Slow RA were significantly higher in occlusion of RCA, rapid RA were significantly higher in occlusion of LAD.
