Construction of a risk assessment scale on acute myocardial infarction and reperfusion arrhythmia with percutaneous coronary intervention

Abstract

Objective To construct a risk assessment scale for patients with acute myocardial infarction (AMI) and reperfusion arrhythmia after percutaneous coronary intervention (PCI) by Delphi expert consultation at home and abroad. Methods From 1st January 2017 to 31st December 2017, we preliminarily drew up risk factors related to patients with AMI and reperfusion arrhythmia after PCI by retrieving and analyzing the heart surgery related risk assessment scale at home and abroad; and we confirmed the weight of risk factors by two rounds of expert consultation on scientific nature, suitability and operability of risk factors with the method of Delphi method and the expert evaluation method. Results The recovery rates of questionnaire were 90% and 95% respectively in two rounds of expert consultation, and the authority coefficient was 0.89 and 0.93. The risk assessment scale constructed for patients with AMI and reperfusion arrhythmia after PCI included 3 first-level risk factors, 13 second-level risk factors. Among weight of risk factors by two rounds of expert consultation, the variation coefficients were all less than 0.2, and the coordination coefficient ranged from 0.20 to 0.34. Conclusions All the experts participating in the investigation are positive with the high consistency of expert opinion, good coordination, professional representativeness and high authority. The constructed risk assessment scale can effectively assess the risk of AMI patients after PCI, reduce the processing time of reperfusion arrhythmia, enhance the ability of nurses to predict the reperfusion arrhythmia of those patients so as to early decrease the incidence of reperfusion risk.
