Yoga shown to slow heart disease

By C. Vidyashankar, MD
DELHI, Jul 13 (Reuters Health) - Yoga can help slow atherosclerosis--the
build-up of fatty deposits on the lining of arteries--in patients with severe
coronary artery disease, according to a report from Delhi, India.
Dr S. C. Manchanda and his team from the All India Institute of Medical
Sciences and the Adhyatma Sadhna Kendra in Delhi, studied 42 men with proven
coronary artery disease. For one year, the men undertook the conventional
regimen of controlling risk factors and modifying their diet, either with or
without the addition of regular yoga sessions.
The yoga was for 90 minutes daily. Exercises included health rejuvenating
exercises, breathing exercises, meditation, relaxation exercises, reflection
and contemplation. The medications for heart disease were continued in both
the groups. Before the treatment began, angiography--a technique that uses a
dye to outline the heart arteries on x-ray--was performed on all the patients.
Writing in the July issue of the Journal of the Association of Physicians of
India, the researchers observed that after one year, the yoga group showed a
significant increase in exercise capacity, reduction in episodes of chest
pain, less need to have their arteries unblocked, decreased body weight, and
lower cholesterol levels.
The investigators conclude that a yoga program is feasible as a way to treat
advanced coronary artery disease.
