目的:分析24 h动态心电图参数与冠心病心力衰竭患者PCI术后预后的关系.方法:回顾性收集2022年3月-2022年3月期间本院收治的接受PCI术的103例冠心病心力衰竭患者的临床资料.PCI术前、术后6 h,所有患者均实施24 h连续动态心电图监测.根据患者的预后情况将患者分为预后良好组和预后不良好组.收集所有患者的基线资料.分析比较两组的基线资料及PCI术前、术后6 h SDNN、SDANN-index、RMSSD及 24 h-QTV变化情况.绘制ROC曲线分析PCI术、术后6 h SDNN、SDANN-index、RMSSD及24 h-QTV对术后预后的预测价值.结果:103 例冠心病心力衰竭患者中,14例发生心血管不良事件.预后良好组、预后不良好组基线资料比较,差异均无统计学意义(P＞0.05).随着时间增长,两组SDNN、SDANN-index、RMSSD及24 h-QTV水平均升高;且术前、术后 6 h 预后不良好组上述参数水平均低于预后良好组(P＜0.05).PCI 术前 SDNN、SDANN-index、RMSSD及24 h-QTV预测预后的AUC分别为0.746、0.798、0.723及0.726;术后SDNN、SDANN-index、RMSSD及24 h-QTV预测预后的AUC分别为0.788、0.815、0.781及0.863.结论:24 h动态心电图参数对于冠心病心力衰竭患者PCI术后预后具有较高的预测价值,但时间因素对SDNN、SDANN-index、RMSSD及24 h-QTV水平有一定影响,术后6 h行24 h动态心电图检查,其预测价值表现得更为突出.
Value of 24-hour holter ECG parameters in prognosis prediction of patients with coronary heart failure after PCI
Objective:To analyze the relationship between 24-hour holter ECG parameters and prognosis of patients with coronary heart failure after PCI.Methods:The clinical data of 103 patients with CHD and heart failure who underwent PCI in our hospital from March 2022 to March 2022 were retrospectively collected.24-hour continuous holter electrocardiogram monitoring was performed in all patients before and 6h after PCI.According to the prognosis of the patients,the patients were divided into good prognosis group and poor prognosis group.Baseline data were collected.Baseline data and the changes of SDNN,SDANN-index,RMSSD and 24h-QTV before and 6 hours after PCI were analyzed and compared between the two groups.ROC curve was drawn to analyze the predictive value of PCI,6 hours SDNN,SDANN-index,RMSSD and 24h-QTV in postoperative prognosis.Results:Among 103 patients with CHD and heart failure,14 had cardiovascular adverse events.There was no significant difference in baseline data between the good prognosis group and the poor prognosis group(P>0.05).With the increase of time,the levels of SDNN,SDANN-index,RMSSD and 24h-QTV increased in both groups.The levels of the above parameters in the group with poor prognosis were lower than those in the group with good prognosis before and 6h after surgery(P<0.05).The prognosis AUC of SDNN,SDANN-index,RMSSD and 24h-QTV before PCI were 0.746,0.798,0.723 and 0.726,respectively.The prognosis AUC of SDNN,SDANN-index,RMSSD and 24h-QTV were 0.788,0.815,0.781 and 0.863,respectively.Conclusion:24h holter ECG parameters have a high predictive value for the prognosis of patients with coronary heart failure after PCI,but time factors have certain effects on SDNN,SDANN-index,RMSSD and 24h-QTV levels,and the predictive value of 24-hour holter ECG examination at 6 hours after surgery is more prominent.
