基于虚拟现实技术的中医传统功法对扩张型心肌病患者心功能及生活质量影响的研究

Effect of Virtual Reality Technology-based Traditional Chinese Medicine Training on Cardiac Function and Quality of Life of Patients with Dilated Cardiomyopathy

目的:探讨基于虚拟现实(VR)技术的中医传统功法对扩张型心肌病(DCM)患者心功能及生活质量的影响。方法:前瞻性选取2022年6月—2023年6月江西省人民医院心血管内科收治的60例DCM患者,采用随机数字表法分为观察组与对照组,各30例。对照组予常规护理,观察组在常规护理的基础上予基于VR技术的中医传统功法干预,均连续干预3个月。对两组入院第1天、干预3个月后的左室射血分数(LVEF)、左心室舒张末期内径(LVEDD)、左室收缩末期内径(LVESD)、N末端B型利钠肽原(NT-proBNP)、6分钟步行试验(6MWT)结果及明尼苏达心力衰竭生活质量问卷(MLHFQ)评分进行统计。结果:与入院第1天相比,两组干预3个月后的LVEF均升高,LVEDD、LVESD均缩短,NT-proBNP均降低,6MWT均延长,且观察组各指标均优于对照组,差异均有统计学意义(P<0.05);与入院第1天相比,两组干预3个月后的躯体领域、情感领域、其他领域评分及MLHFQ总分均降低,且观察组均低于对照组,差异均有统计学意义(P<0.05)。结论:针对DCM患者,采用基于VR技术的中医传统功法干预,能有效改善其心功能,降低NT-proBNP水平,延长6MWT,并提高患者生活质量。

Objective:To investigate the effect of virtual reality(VR)technology-based traditional Chinese medicine training on cardiac function and quality of life of patients with dilated cardiomyopathy(DCM).Method:A total of 60 patients with DCM who were admitted to the Department of Cardiovascular Medicine,Jiangxi Provincial People's Hospital from June 2022 to June 2023 were selected and randomly divided into the observation group and the control group by random number table method,with 30 patients in each group.The control group received routine nursing.On this basis,the observation group received VR technology-based traditional Chinese medicine training.All patients received 3 months of continuous intervention.Left ventricular ejection fraction(LVEF),left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD),N-terminal B-type natriuretic peptide(NT-proBNP),6-minute walking test(6MWT)results and the Minnesota living with heart failure questionnaire(MLHFQ)scores in the two groups were statistically analyzed on the first day of admission and 3 months after intervention.Result:Compared with the first day after admission,LVEF increased,LVEDD,LVESD and NT-proBNP decreased,and 6MWT were prolonged after 3 months of intervention in two groups,the above indicators in the observation group were better than those in the control group,the differences were statistically significant(P<0.05).Compared with the first day after admission,the scores of the physical domain,emotional domain,other domains and MLHFQ total scores were decreased in the two groups after 3 months of intervention,and the above scores of the observation group were lower than those in the control group,the differences were statistically significant(P<0.05).Conclusion:For patients with DCM,VR technology-based traditional Chinese medicine training can effectively improve their cardiac function,lower NT-proBNP level,prolong 6MWT and improve the quality of life.
