Breathing Training for Older Patients with Controlled Isolated Systolic Hypertension

Area of Science:

• Cardiology
• Respiratory Physiology
• Geriatric Medicine

Background:

• Isolated systolic hypertension (ISH) is a prevalent condition in older adults, often posing management challenges with conventional therapies.
• Effective non-pharmacological interventions for ISH are sought to complement existing treatment strategies.

Purpose of the Study:

• To evaluate the efficacy of slow breathing training, with and without an inspiratory load, in reducing resting blood pressure in older patients with ISH.
• To determine if inspiratory loading enhances the blood pressure-lowering effects of slow breathing.

Main Methods:

• Thirty older adults with ISH were randomized into three groups: loaded breathing (inspiratory load), unloaded breathing, or a control group.
• Participants trained for 30 minutes daily for 8 weeks, with blood pressure and heart rate monitored throughout the study and a follow-up period.

Main Results:

• Slow breathing training significantly reduced systolic blood pressure by 18 mmHg (loaded) and 11 mmHg (unloaded) compared to baseline.
• The reduction in systolic blood pressure was significantly greater in the loaded breathing group.
• Systolic blood pressure reductions persisted for up to 6 weeks post-training in the loaded group.

Conclusions:

• Slow breathing training, especially when incorporating an inspiratory load, is a highly effective method for reducing resting systolic and pulse pressures in ISH patients.
• This technique represents a promising, non-pharmacological adjunct for the management of isolated systolic hypertension.
