Coronary heart disease remains the No. 1
cause of death and disability in the United States for both men and women.
Almost half a million Americans die of coronary heart disease each year, and
approximately half of these deaths are women. Preventing coronary heart
disease remains the leading challenge to biomedical researchers and public
health workers today. On the average, almost three Americans will suffer a
heart attack every minute of the day, adding up to almost one and a half
million attacks each year.
At the National Heart, Lung, and Blood
Institute (NHLBI) and the American Heart Association (AHA), we are committed
to addressing this challenge by encouraging fundamental research on the causes
and treatment of coronary heart disease and by strengthening our disease
prevention and health promotion programs. We have seen a dramatic decline in
coronary heart disease mortality during the past two decades. This has been
accompanied by a growing interest in making lifestyle changes which can reduce
the risks for coronary heart disease.
With prevention as our ultimate goal,
the communication of health information to the public will continue to be an
important part of our activities. We have long provided the public with
educational materials to help reduce three primary risk factors: high blood
pressure, cigarette smoking and high blood cholesterol. In recent years, the
NHLBI and the AHA have addressed another major risk factor sedentary
lifestyle, or physical inactivity. The results of various studies now show
that regular physical activity can help reduce the risk of heart disease. It
also can help control other contributing risk factors, including obesity and
diabetes. We hope that this booklet will help to stimulate a sensible exercise
program as one way of keeping a healthy heart.
We are delighted to join together to
provide this message about physical activity. We believe that collaboration is
one important way of performing common public health missions. Revising and
distributing this publication is only one example of this ongoing partnership.
