In a nutshell
This study analyzed data from previous studies investigating if voluntary slow breathing exercises (VSBE) can improve cardiovascular disease symptoms.
They found that VSBE resulted in reduced heart rate and blood pressure in patients with cardiovascular disease.
Some background
Increased heart rate and blood pressure can cause significant complications for patients with cardiovascular (heart and circulatory system) disease. There are many medications to manage these symptoms, however not all patients respond well to pharmacological (drug) therapy.
Voluntary slow breathing exercises (VSBE) are self-controlled breathing patterns which aim to slow respiratory (breathing) rates. Evidence suggests that reducing respiratory rates may also reduce heart rate and blood pressure levels.
Methods & findings
This study compared data from a range of studies to determine any effects of VSBEs on cardiovascular symptoms. This study included results from 269 individuals with cardiovascular disease, across 6 separate investigations. Patients were assigned to either VSBE or natural breathing. The trials lasted between 2 weeks and 6 months. Heart rate and blood pressure were monitored during and at the end of the trials.
VSBE resulted in an average reduction in heart rate of 1.72 beats/min, which was statistically significant. Systolic (during heart beat) blood pressure was reduced by 6.36 mm Hg. Diastolic (during rest) blood pressure was reduced by 6.39 mm Hg.
The bottom line
This study concluded that voluntary slow breathing exercises can reduce heart rate and blood pressure in patients with cardiovascular disease.
The fine print
The number of studies/participants was low for a study of this nature. Longer studies are needed to confirm the effects.
What’s next?
If you have any concerns regarding managing cardiovascular symptoms, please discuss this with your physician.
