Analysis of the correlation between preoperative dynamic electrocardiogram parameters and the prognosis of patients with coronary heart disease treated with PCI
Objective To explore the correlation between preoperative dynamic electrocardiogram parameters and the prognosis of patients with coronary heart disease treated with PCI.Methods A retrospective analysis was conducted on the clinical data of 100 patients with coronary heart disease who underwent PCI treatment in our hospital from January 2021 to December 2022.All patients underwent PCI treatment and underwent dynamic electrocardiogram examination before surgery;Follow up for 1 year,divide patients into poor prognosis and good prognosis groups based on whether they have adverse cardiovascular events,and compare the differences in SDNN,SDNNI,SDANN,and rMSSD between the two groups;And draw ROC curves to analyze the clinical value of dynamic electrocardiogram parameters in predicting the prognosis of coronary heart disease patients after PCI treatment.Results 100 patients were followed up for 1 year,with a total of 23 cases experiencing adverse cardiovascular events;The SDNN,SDNNI,SDANN,and rMSSD of the poor prognosis group were(78.54±6.22)ms,(38.96±4.58)ms,(55.12±5.36)ms,and(22.65±2.39)ms,which were lower than those of the good prognosis group(125.41±10.33)ms,(58.03±5.89)ms,(84.74±6.87)ms,and(45.44±4.52)ms(P<0.05);Drawing ROC curves shows that the AUC of SDNN,SDNNI,SDANN,rMSSD,and combined examination for predicting the prognosis of coronary heart disease after PCI treatment are 0.789,0.784,0.801,0.813,and 0.973,respectively,with the highest value of combined examination.Conclusions Preoperative dynamic electrocardiogram examination can predict the prognosis of patients with coronary heart disease undergoing PCI treatment well,and it is necessary to improve the examination as soon as possible to guide treatment work and better improve patient prognosis.
