Development of nursing care to improve QOL and prognosis of CHF-patients using

本研究旨在评估腿部热疗（LTT）对心力衰竭（CHF）患者睡眠和心功能的影响，作为护理的基础数据。对chf患者进行LTT，采用45℃远红外加热，持续15分钟，连续3晚。评估包括血流动力学、血流介导的血管舒张反应（%FMD）指标的内皮功能，以及全多导睡眠图的睡眠参数。LTT显著改善了%FMD和血浆脑利钠肽水平，但血流动力学没有恶化。睡眠结构分析也显示，LTT显著减少轻度睡眠，增加深度睡眠，表明睡眠质量得到改善。LTT不仅能有效改善CHF患者的血管功能，还能改善睡眠结构。这些结果支持LTT作为chf患者的非药物和家庭补充治疗的有效性，以改善他们的生活质量和心血管结局。

We designed this study to evaluate the effects of leg thermal therapy (LTT) on sleep and cardiac function in patients with cardiac heart failure (CHF) as basic data for nursing care. LTT was applied to CHF-patients using far-infrared heating at 45oC for 15 minutes for 3 consecutive nights. Evaluation included hemodynamics, endothelial function indexed by the flow mediated vasodilation response (%FMD), and sleep parameters from full polysomnography. LTT significantly improved %FMD and plasma brain natriuretic peptide level without deteriorating hemodynamics. Analysis of sleep structure also revealed that LTT significantly decreased light sleep and increased deep sleep, indicating improvement in sleep quality. LTT was effective to improve not only vascular function but also sleep structure in CHF patients. These results support the effectiveness of LTT as a non-pharmacological and home complementary therapy for CHF-patients to improve their QOL as well as cardiovascular outcome.
