“The research is suggestive, but not definitive,” said Glenn N. Levine, M.D., chairman of the group of cardiovascular disease experts who reviewed recent science to determine whether meditation could help reduce heart disease risks.
The experts found a potential benefit to the heart from meditation, but mostly the small studies were not conclusive.
“Overall, studies of meditation suggest a possible benefit on cardiovascular risk, although the overall quality and in some cases quantity of study data is modest,” said the statement, released Thursday.

Some types of meditation included in the research were: Samatha; Vipassana (Insight Meditation); Mindful Meditation; Zen Meditation (Zazen); Raja Yoga; Loving-Kindness (Metta); Transcendental Meditation; and Relaxation Response.
