基于CPET的康复运动对冠心病PCI术后患者心脏自主神经功能与生活质量的影响

Effects of rehabilitation exercise based on CPET on cardiac autonomic nervous function and quality of life in patients with coronary heart disease after PCI

目的探讨基于心肺运动试验(CPET)的康复运动对冠心病PCI术后患者心脏自主神经功能[心率减速力(DC)、连续心率减速力(DRs)、心率变异性(HRV)]与生活质量的影响。方法选取2019年8月至2022年8月收治的106例冠心病PCI术后患者,采用随机数字表法将其分为对照组和观察组,各53例。对照组给予常规治疗,观察组在对照组基础上实施基于CPET的康复运动。比较两组的治疗效果。结果干预后,观察组的峰值公斤摄氧量、无氧阈、峰值氧脉搏均高于干预前及对照组(P<0.05)。干预后,观察组的峰值功率、峰值代谢当量均高于干预前及对照组(P<0.05)。干预后,观察组的心率减速力(DC)、DR4、DR8、RR间期总体标准差(SDNN)、RR间期平均值的标准差(SDANN)、相邻RR间期差值的均方根(RMSSD)均高于干预前及对照组(P<0.05)。干预后,观察组的Barthel指数、中国心血管病人生活质量评定问卷(CCQQ)评分高于干预前及对照组(P<0.05)。结论基于CPET的康复运动能够明显增强冠心病PCI术后患者的心肺功能与运动能力,提高心脏自主神经功能,改善生活质量。

Objective To explore the effects of rehabilitation exercise based on cardiopulmonary exercise test(CPET)on cardiac autonomic nervous function[deceleration capacity of rate(DC),heart rate decleration runs(DRs)and heart rate variability(HRV)]and quality of life in patients with coronary heart disease after percutaneous coronary intervention(PCI).Methods A total of 106 patients with coronary heart disease after PCI admitted from August 2019 to August 2022 were selected and divided into control group and observation group by random number table method,with 53 cases in each group.The control group was given routine treatment,and the observation group was given rehabilitation exercise based on CPET on the basis of the control group.The therapeutic effects of the two groups were compared.Results After intervention,the peak oxygen uptake per kilogram,anaerobic threshold and peak oxygen pulse in the observation group were higher than those before intervention and in the control group(P<0.05).After intervention,the peak power and peak metabolic equivalent of the observation group were higher than those before intervention and in the control group(P<0.05).After intervention,DC,DR4,DR8,standard diviation of NN intervals(SDNN),standard diviation average of NN intervals(SDANN)and root mean square of the successive normal sinus R-R interval difference(RMSSD)in the observation group were higher than those before intervention and in the control group(P<0.05).After intervention,the Barthel index and China Cardiovascular Quality of Life Questionnaire(CCQQ)scores of the observation group were higher than those before intervention and in the control group(P<0.05).Conclusion Rehabilitation exercise based on CPET can significantly enhance the cardiopulmonary function and exercise capacity of patients with coronary heart disease after PCI,elevate cardiac autonomic nervous function,and improve the quality of life.
