简要总结
This was a randomized, single-blind, controlled, community-based trial comparing the clinical efficacy of the Transcendental Meditation program on carotid intima-media thickness and major adverse cardiovascular events in 197 African American men and women at risk for atherosclerotic CVD. After baseline testing, participants were randomly assigned to either a stress reduction program (Transcendental Meditation) or a standard health education program. Follow up was conducted over one year and 12 years.
详细描述
This was a randomized, single-blind, controlled, community-based trial comparing the clinical efficacy of the Transcendental Meditation (TM) program carotid intima-media thickness and major adverse cardiovascular events (MACE) in 197 African American men and women at high risk for ASCVD. This trial compared the efficacy of the TM program to health education over one year on cIMT. Eligible participants were randomly allocated to either the TM program or health education (HE). The primary outcome was carotid intima-media thickness (IMT) assessed by B-mode ultrasonography at baseline and 12 months. Secondary outcomes were blood pressure, lipids, lifestyle, psychosocial stress and MACE. Fatal and nonfatal clinical events were assessed over one year, and mortality after 12 years.
