Stress reduction through
the Transcendental Meditation program may reduce atherosclerosis and risk
of heart attack and stroke
Learning
to relax and reduce stress through the practice of the Transcendental
Meditation (tm) technique may reduce atherosclerosis and risk of heart
attack and stroke-according 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.
"This finding that the disease process in the arteries can be reduced
through the TM program may have vast implications for the current
management of cardiovascular disease and health care costs," says
Amparo Castillo-Richmond, M.D., lead author of the study and Assistant
Professor of Medicine at the College of Maharishi Vedic Medicine.
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 cardio-vascular disease were randomly
assigned to the Transcendental Meditation program or to a health education
control group. Sixty men and women volunteers completed pretests and
posttests 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 a
predictor of heart attack and stroke.
Reduced risk of heart
attack and stroke
The study's findings were
impressive. Subjects practicing the TM program showed a decrease of
0.098mm in IMT wall thickness, whereas participants in the health
education control group showed an increase of 0.054mm. Based on two
previous clinical observations, a 0.1mm decrease in IMT would indicate an
approximate 11 percent decrease in risk of heart attack and a 7.7 percent
to 15 percent 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 was no significant
differences in baseline characteristics, intervention duration or
attrition between the two groups.
Robert Schneider, M.D., second author of the study and director of the NIH-sponsored
Center for Natural Medicine and Prevention (CNMP) at the College of
Maharishi Vedic Medicine, states, "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."
Self-repair mechanism
activated
"Taken together, these
and other findings suggest that the distinct state of 'restful alertness'
experienced during the TM technique may be triggering self-repair
homeostatic mechanisms in the body, which lead to the regression of
atherosclerosis," says Schneider.
NIH to sponsor follow-up
studies in Los Angeles
Hector Myers, Ph.D.,
coauthor of the study and Professor of Psychology at UCLA and Professor of
Psychiatry at Drew University, is overseeing three follow-up studies on
the TM program conducted 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 the National Center for Complementary and
Alternative Medicine. The studies will be evaluating the current findings
in a larger group of African Americans with heart disease and will also be
studying possible mechanisms by which stress reduction through the TM
program may affect the cardiovascular disease process.
Other
coauthors of the current study are: Charles Alexander, Ph.D.; Sanford
Nidich, Ph.D.; Maxwell Rainforth, Ph.D.; and John Salerno, Ph.D., from the
Center for Natural Medicine and Prevention at Maharishi University of
Management College of Maharishi Vedic Medicine; and Robert Cook, M.D., and
Chinelo Haney, project director, from the Department of Radiology and
Biobehavioral Research Center at Drew University in Los Angeles.
