慢性心力衰竭（HF）患者的睡眠质量通常会受到损害，这可能会恶化他们的生活质量甚至预后。腿部热疗 (LTT)，即局部腿部加温，已被证明可以改善心力衰竭患者的内皮功能、氧化应激和心脏功能。然而，其对心力衰竭患者睡眠质量的短期影响尚未得到评估。 23 名稳定心力衰竭患者中，有 18 名连续 3 晚在睡前接受 LTT（45 摄氏度加温 15 分钟，保温 30 分钟），另外 5 名患者作为对照。主观睡眠质量通过圣玛丽医院睡眠问卷、小栗白川安昙睡眠量表和Epworth嗜睡量表进行评估，并通过多导睡眠图进行客观评估。 LTT 显着改善了主观睡眠质量，具体表现为睡眠深度 (p < 0.01)、睡眠持续时间 (p < 0.05)、觉醒次数 (p < 0.01)、午睡持续时间 (p < 0.01)、睡眠质量 (p < 0.05) 和睡眠满意度 (p < 0.05)。 N1 睡眠阶段轻微但显着的下降（p < 0.01）和 N2 睡眠阶段的增加（p < 0.05）也客观地证实了这一点。控制措施没有发生重大变化。因此，短期LTT可以改善心力衰竭患者的主观和客观睡眠质量。 LTT 可以作为改善这些患者睡眠质量的补充疗法。
Sleep quality is often impaired in patients with chronic heart failure (HF), which may worsen their quality of life and even prognosis. Leg thermal therapy (LTT), topical leg warming, has been shown to improve endothelial function, oxidative stress, and cardiac function in patients with HF. However, its short-term influence to sleep quality has not been evaluated in HF patients. Eighteen of 23 patients with stable HF received LTT (15 min of warming at 45 A degrees C and 30 min of insulation) at bedtime for 3 consecutive nights and 5 patients served as control. Subjective sleep quality was evaluated by St. Mary's Hospital Sleep Questionnaire, Oguri-Shirakawa-Azumi Sleep Inventory, and Epworth sleepiness scale, and also objectively evaluated by polysomnography. LTT significantly improved subjective sleep quality indicated by depth of sleep (p < 0.01), sleep duration (p < 0.05), number of awaking (p < 0.01), nap duration (p < 0.01), sleep quality (p < 0.05), and sleep satisfaction (p < 0.05). It was also objectively affirmed by a slight but significant decrease of sleep stage N1 (p < 0.01), and increase in sleep stage N2 (p < 0.05). No significant changes occurred in the controls. Hence, the short-term LTT could improve subjective and objective sleep quality in patients with HF. LTT can be a complimentary therapy to improve sleep quality in these patients.
