Stress Reduction Through The Transcendental Meditation Program May Reduce
Atherosclerosis And Risk of Heart Attack and Stroke
LOS ANGELES, CA--Learning to relax and reduce stress through the practice of the
Transcendental Meditation (TM) technique may reduce atherosclerosisand risk of heart
attack and strokeaccording to findings published today in the American Heart
Association journal Stroke.
This is the first controlled study to suggest that stress reduction by itself can
reduce atherosclerosis without changes in diet and exercise, according to a team of
researchers from UCLA and Charles R. Drew University of Medicine and Science in Los
Angeles and Maharishi University of Management (M.U.M.) College of Maharishi Vedic
Medicine in Fairfield, Iowa.
"We are very encouraged by these preliminary findings and are looking forward to
replicating them in a larger sample of African Americans with heart disease," says
Hector Myers, PhD, coauthor of the study and professor of psychology at UCLA and professor
of psychiatry at Drew University.
Atherosclerosis is the hardening of the arteries accompanied by the buildup of fat
deposits in the artery walls. It leads to cardiovascular disease (CVD), the number one
cause of death for all Americans. CVD is particularly lethal to African Americans who are
twice as likely to die from the illness as whites.
The study was supported by a grant from the National Heart, Lung and Blood Institute
and was conducted at Drew University in collaboration with the M.U.M. Center for Natural
Medicine and Prevention.
Hypertensive African Americans who were at risk for cardiovascular disease were
randomly assigned to the Transcendental Meditation program or to a health education
control group. Sixty men and women volunteers completed pretests and post-tests over an
average intervention period of about seven months. The level of fatty substances deposited
on participants' arterial walls, or carotid intima-media thickness (IMT), was
evaluated by ultrasound. IMT is a widely used surrogate measure of coronary
atherosclerosis and predictor of heart attack and stroke.
Reduced risk of heart attack and stroke
The results showed that subjects practicing the TM program had a decrease of 0.098mm in
IMT wall thickness, whereas participants in the health education control group had an
increase of 0.054mm. Based on two previous clinical observations, a 0.1mm decrease in IMT
would indicate an approximate 11% decrease in the risk of heart attack and a 7.7% to 15%
reduction in risk of stroke.
Results comparable to medications and lifestyle modification
The reductions found in the TM group were comparable to those achieved by
lipid-lowering medications and intensive lifestyle modification programs. There were no
significant differences in baseline characteristics, intervention duration, or attrition
between the two groups.
Amparo Castillo-Richmond, MD, lead author of the study and assistant professor of
Medicine at the College of Maharishi Vedic Medicine, says, "Cardiovascular disease is
associated with psychological stress. Previous research has found that the TM program
decreases coronary heart disease risk factors, including hypertension, oxidized lipids,
stress hormones and psychological stress, and is associated with reduced cardiovascular
disease and death in African Americans and the general population."
Prevention-oriented approach
Robert Schneider, MD, second author of the study and director of the M.U.M. Center for
Natural Medicine and Prevention, says, "Taken together, these and other findings
suggest that the distinct state of restful alertness' gained during the TM
technique may be triggering self-repair homeostatic mechanisms in the body, which lead to
the regression of atherosclerosis. As a modality for both prevention and treatment, the TM
program could have vast implications for the current management of cardiovascular disease
and health care costs."
NIH to sponsor follow-up studies in Los Angeles
Three follow-up studies on the TM program are in progress or will begin in the next two
months at Drew University in collaboration with Cedars-Sinai Medical Center in Los Angeles
and M.U.M. The studies are supported by grants from the National Institutes of
Health's Heart, Lung and Blood Institute and National Center for Complementary and
Alternative Medicine. In addition to replicating the current findings, the studies will
investigate possible mechanisms by which stress reduction through the TM program may
affect the cardiovascular disease process.

director, from the Department of Radiology and Biobehavioral Research Center at Charles R.

Maxwell Rainforth, PhD; and John Salerno, PhD, from the Center for Natural Medicine and
Prevention at Maharishi University of Management College of Maharishi Vedic Medicine.
