Device-guided slow breathing as a non-pharmacological approach to antihypertensive treatment: efficacy, problems and perspectives
Key result
Device-guided slow breathing did not significantly reduce office blood pressure compared to listening to music (-7.5/-1.0 mmHg vs -12.2/-5.5 mmHg) in patients with type 2 diabetes and hypertension.

Implication
Device-guided slow breathing exercises do not significantly reduce blood pressure compared to listening to music in patients with type 2 diabetes and hypertension.
Structured PICO
Does device-guided slow breathing reduce blood pressure in patients with type 2 diabetes mellitus and hypertension?
P
Population
30 patients with type 2 diabetes mellitus and hypertension under antihypertensive drug treatment, followed for 8 weeks.
I
Intervention
Device-guided slow breathing exercise (RESPeRATE) aimed at obtaining a respiratory frequency of less than 10 breaths per minute
C
Comparator
Listening to various kinds of random music with a discman (placebo)
O
Outcome
Changes in clinic and home blood pressure and quality of lifesurrogate
Main Result
Absolute Event Rate: -7.5% vs -12.2%
Device-guided slow breathing exercises do not significantly reduce blood pressure compared to listening to music in patients with type 2 diabetes and hypertension.
Limitations
- Possible occurrence of autonomic dysfunction in hypertensive patients with diabetes
- Possible presence of clinically not evident pulmonary disease
- Only 60% of patients in the intervention group successfully lowered their breathing rates to the target
- No measure of autonomic cardiovascular regulation was obtained
- Possible presence of microalbuminuria was not investigated
- Focus on patients with type 2 diabetes who may have longstanding disease
- Possible occurrence of autonomic dysfunction in diabetic patients which may blunt the response to the intervention

Parati et al. (2006) conducted an editorial in Type 2 diabetes mellitus and hypertension (n=30). Device-guided slow breathing (RESPeRATE) vs. Listening to random music with a discman was evaluated on Office systolic blood pressure reduction. Device-guided slow breathing did not significantly reduce office blood pressure compared to listening to music (-7.5/-1.0 mmHg vs -12.2/-5.5 mmHg) in patients with type 2 diabetes and hypertension.
