个性化营养支持联合呼吸训练对慢性心力衰竭患者心脏康复的影响

摘要

目的 探讨个性化营养支持联合呼吸训练对慢性心力衰竭患者心脏康复的影响。方法 本次研究共纳入62例慢性心力衰竭病例，入组对象全部为2022年10月至2025年12月区间内在本院接受住院诊疗的患者。所有入组病例通过随机数字表法完成组别划分，分别归入对照组与观察组两个队列，两组各分配31例患者。对照组采取常规护理，观察组实施个性化营养支持联合呼吸训练，对比两组患者的心功能指标、呼吸功能指标、运动耐量指标。结果 观察组患者在干预后的LVEF、LVEDD、NT-proBNP等各项心功能指标均优于对照组（P＜0.05）。观察组患者干预3个月后的FEV1、FVC、MVV等呼吸功能指标均优于对照组（P＜0.05）。观察组患者干预后的6分钟步行测试距离优于对照组（P＜0.05）。结论 个性化营养支持联合呼吸训练能有效改善慢性心力衰竭患者的心功能、呼吸功能及运动耐量，促进心脏康复。

Abstract

Objective To explore the impact of personalized nutritional support combined with respiratory training on cardiac rehabilitation in patients with chronic heart failure.
Methods A total of 62 cases of chronic heart failure were included in this study, all of whom were hospitalized in our hospital between October 2022 and December 2025. All enrolled cases were randomly assigned to either the control group or the observation group using a random number table, with 31 patients in each group. The control group received routine care, while the observation group underwent personalized nutritional support combined with respiratory training. The cardiac function, respiratory function, and exercise tolerance indicators of both groups were compared.
Results After the intervention, the observation group exhibited superior cardiac function indicators such as LVEF, LVEDD, and NT-proBNP compared to the control group (P < 0.05). The respiratory function indicators of the observation group, including FEV1, FVC, and MVV, were also significantly better than those of the control group after 3 months of intervention (P < 0.05). Additionally, the 6-minute walk test distance in the observation group was superior to that of the control group (P < 0.05).
Conclusion   Personalized nutritional support combined with respiratory training can effectively improve cardiac function, respiratory function, and exercise tolerance in patients with chronic heart failure, promoting cardiac rehabilitation.
