Risk factors and nursing of reperfusion arrhythmia in emergency percutaneous coronary intervention

Abstract

Objective To explore the risk factors of reperfusion arrhythmia in emergency percutaneous coronary intervention （ PCI ） in order to provide the evidence for the prospective nursing .Methods One hundred and twenty-three ST elevated acute myocardial infarction patients with emergency PCI within 12 h from June 2011 to June 2013 were chosen , and the incidence rate of reperfusion arrhythmia during the operation was evaluated.Seventy-one patients with reperfusion arrhythmia during the operation were chosen as the observation group, and 52 patients without reperfusion arrhythmia were chosen as the control group .The age, gender, diabetes , hypertension , hyperlipidemia , preinfarction angina , heavy smoking , mood fluctuations , CK-MB peak value, increased white blood cell count , heart failure, cardiogenic shock, multi-vessel vascular lesions and attack-to-ballon time were compared between two groups . The multivariate logistic regression was used to evaluate the independent risk factors of the occurrence of reperfusion arrhythmia .Results The incidence rate of reperfusion arrhythmia in emergency PCI in patients was 57.7%（71/123）.Return to multi-factor analysis ,the mood fluctuations , multi-vessel vascular lesions and attack-to-ballon time less than 6 h are the most important risk factors of the incidence of reperfusion arrhythmia .The male and preinfarction anginas are the protection factors.Conclusions We should pay attention to the high risk factors of reperfusion arrhythmia in emergency PCI, and observe the ECG monitoring closely , and carry out nursing and rescue actively so as to make the patients safety during the operation period .
