摘要

背景:

全身性熱療法(STT)已與慢性心力衰竭(CHF)患者的有益效果相關聯。然而,由於它需要專門且寬敞的設施以及受過訓練的人員,使其在CHF患者的日常護理中難以實踐。

目的:

本研究的目的是確定腿部熱療法(LTT)是否對CHF患者具有與STT相似的正面影響。方法和結果二十名CHF患者(57 ± 17歲,左心室射血分數= 30 ± 10%)接受了20分鐘的LTT(45°C)。治療後立即,核心溫度上升(+0.3 ± 0.3°C)(p <0.01)。儘管LTT對心率、收縮動脈壓和舒張血壓沒有顯著影響,但它增加了心輸出量(混合靜脈氧飽和度; +2 ± 3%)並降低了肺毛細血管楔壓(-2 ± 2 mmHg)。 LTT顯著改善了流動介導的血管舒張作用(FMD)從4.8 ± 2.6%增加到7.1 ± 3.6%,抗氧化標誌物,硫醇從4.0 ± 0.7增加到4.5 ± 0.9μmoL/g,以及氧化脫氧核糖核酸(DNA)損傷標誌物,尿液8-羥基-2’脫氧鳥苷(8OHdG)從100減少到82 ± 3%,分別(p <0.05)。沒有患者與LTT有任何不良反應。結論LTT急性改善了CHF患者的FMD和氧化壓力。儘管LTT的長期效果尚待研究,但其與STT相當的實用性使其成為CHF患者的一項有吸引力的治療策略。

Abstract

Background:

Systemic thermal therapy (STT) has been associated with beneficial effects in patients with chronic heart failure (CHF). The fact, however, that it requires a dedicated as well as spacious facility and trained personnel makes it difficult to practice in the daily care of patients with CHF.

Objective:

The aim of this study was to determine whether the leg thermal therapy (LTT) has a positive impact similar to that of STT in patients with CHF. Methods and Results Twenty patients with CHF (57 ± 17 years old, left ventricular ejection fraction=30 ± 10%) received LTT (45°C) for 20 minutes. Immediately after the treatment, the core temperature had increased (+0.3 ± 0.3°C) (p<0.01). While the LTT had no significant effects on the heart rate, systolic arterial pressure, and diastolic blood pressure, it increased the cardiac output (mixed venous oxygen saturation; +2 ± 3%) and decrease the pulmonary capillary wedge pressure (-2 ± 2 mmHg). The LTT significantly improved the flow-mediated vasodilatation (FMD) from 4.8 ± 2.6 to 7.1 ± 3.6%, the antioxidative markers, thiol from 4.0 ± 0.7 to 4.5 ± 0.9 μmoL/g, and the marker of oxidative deoxyribonucleic acid (DNA) damage, urine 8-hydroxy-2’deoxyguanosine (8OHdG) from 100 to 82 ± 3%, respectively (p<0.05). No patient had any adverse effects associated with LTT. Conclusion LTT acutely improved FMD, and oxidative stress in patients with CHF. Although the long-term effect of LTT remains to be investigated, its practicality which is comparable to that of STT would make it an attractive therapeutic strategy for patients with CHF.
