| Objective:Acute myocardial infarction patients with reperfusion arrhythmia within 24 hours after emergency PCI were collected from the department of cardiology,the first affiliated hospital of Kunming medical university,and the clinical factors that may affect their occurrence were analyzed to guide clinicians to prevent and manage the occurrence of reperfusion arrhythmia.Method:Retrospective study was used to collect 80 AMI patients who underwent emergency PCI in our hospital.They were divided into RA group and non-RA group according to the occurrence within 24 hours.the factors that may affect the occurrence of RA were recorded:gender,smoking,hypertension,hyperlipidemia,diabetes,heart failure,whether angina pectoris occurred before myocardial infarction,the location of myocardial infarction,whether it was polyvascular disease,whether there was cardiac enlargement,the time of myocardial infarction to PCI treatment,etc.Data statistics using SPSS 17.0 analysis,single factor analysis using chi-square test,m ulti-factor analysis using logistic regression analysis,with P value<0.05 as the difference is statistically significant.Results:80 patients with acute myocardial infarction,reperfusion arrhythmia were found in 47 patients,accounting for 58.75%.There was no significant difference for the occurrence of RA in gender,age,smoking,hyperlipidemia,heart failure,the location of myocardial infarction,multiple vascular lesions,cardiac enlargement,myocardial infarction to PCI time(P>0.05).There were statistically significant difference for the occurrence of RA in hypertension,angina pectoris before myocardial infarction,diabetes(P=0.039,0.003,0.001).There were statistically significant difference in anterior wall myocardial infarction and tachyarrhythmia(P=0.025),while inferior wall myocardial infarction and bradyarrhythmia was also(P=0.001).Conclusions:Hypertension,diabetes may be risk factors for RA;angina pectoris before myocardial infarction may be a protective factor for RA;the type of RA may be related to the location of myocardial infarction,in which anterior wall myocardial infarction often occurs tachyarrhythmia;inferior wall myocardial infarction often occurs bradyarrhythmia. |
