Background and Objectives:
It is known that slow breathing (<10 breaths/min) reduces blood pressure (BP). But, this phenomenon has never been studied in hypertensive patients with chronic kidney disease. Thus, the aim isto evaluate the responses of the BP and heart rate (HR) using device-guided slow breathing (breathe with interactive music (BIM) or lounge music in hypertensive patients with chronic kidney disease.
Design and Methods:
In all, 32 hypertensive patients with chronic kidney disease were enrolled. The BIM device was used for 15 min. during eight weeks in hemodialysis sessions. The patients that did not use this device listened to lounge music during this same period. BP and HR were measured for 5 min before the use of the device (n = 16) or while subjects listened to lounge music (n = 16); it was measured again for 15 min while in use and finally, 5 min after the interventions. These parameters were measured in pre and post hemodialysis too.
BIM device reduced respiratory rate from 15.8 ± 3.5 breaths/min to 8.1 ± 2.5 (P < 0.05); this variable was not affected by lounge music. After eight weeks, both interventions did not reduce pre hemodialysis BP, but the post hemodialysis BP reduced significantly (P < 0.05) with BIM device (from 158.4 ± 28.6/93.6 ± 13.8 to 143.7 ± 24.4/86.1 ± 12.4). Lounge music also reduced the BP, but not statistically significant (from 143.1 ± 18.9/84.4 ± 12 to 136.5 ± 25/80.5 ± 11.7). HR did not change.
Slow breathing exercise seems to be a non-pharmacological treatment modality that can be used in hypertensive patients with chronic kidney disease and it reduces the post hemodialysis BP.
