Benefits of yoga for lowering blood pressure in cardiac-rehab pateints
Klinik Roderbirken der Deutschen Rentenversicherung, in Germany reported their findings during the EuroPREVENT 2010 meeting.
First, the details.
- 340 male cardiac-rehabilitation patients with high blood pressure following their initial heart attack or percutaneous coronary intervention (coronary angioplasty) were randomly assigned to a “relaxation” group for 5 sessions per week lasting 30- to 60-minutes for 3 weeks.
- Relaxation #1: Standard intensive cardiac-rehab program that included PMR (progressive muscle relaxation; a technique based on alternate tensing and relaxing of muscles)
- Relaxation #2: Viniyoga (most of the patients didn’t realize they were doing yoga)
- Cardiac rehabilitation is a medically supervised program to help heart patients recover quickly and improve overall physical and mental functioning.
- After 3 weeks, men were encouraged to continue their programs at home and told that a questionnaire would be sent to them after 6 months.
And, the results.
- At 3 weeks, systolic blood-pressure in men in the Relaxation #2 (yoga group) declined by 8 mmHg vs 6 mmHg in the Relaxation #1 group.
- Among men with the highest systolic blood pressures (greater than 140 mmHg), declines in the yoga group were significantly more pronounced: 21 mmHg vs 13 mmHg in the Relaxation #1 group.
- Most of the patients were on multidrug antihypertensive regimens.
- By 6 months, 50% of Relaxation #1 patients continued therapy at least once per week vs 30% of the Relaxation #2 (yoga group).
The bottom line?
The author’s concluded, it’s too soon to make yoga an integral part of cardiac-rehab. However, ongoing studies in patients with higher blood pressure might change this.
They were impressed that 30% of the patients (mostly “low educated” males) continued with yoga for 6 months.
