Stress reduction in the secondary prevention of cardiovascular disease: randomized, controlled trial of transcendental meditation and health education in Blacks.
Circulation. Cardiovascular quality and outcomes November 1, 2012 Robert H Schneider, Clarence E Grim, Maxwell V Rainforth et al.
A randomized controlled trial of 201 Black men and women with coronary heart disease compared the Transcendental Meditation (TM) program with health education. Over an average follow-up of 5.4 years, the TM group showed a 48% reduction in the combined risk of all-cause mortality, myocardial infarction, or stroke. Systolic blood pressure dropped by 4.9 mmHg, and anger expression scores improved. The authors argue that TM may be useful for secondary prevention of cardiovascular disease in this population.
