The cardiovascular system is made up of the heart and blood
vessels. Cardiovascular diseases (CVD), as defined by the
American Heart Association, include coronary heart disease
(coronary artery disease, ischemic heart disease), stroke (brain
attack), high blood pressure (hypertension), and rheumatic heart
disease. More than 80 million U.S. adults have one or more forms
of CVD. Each year in the U.S., cardiovascular diseases top the
list of most serious health problems. Coronary heart disease is
the leading cause of death, and stroke is the fourth leading
cause of death. Stroke is also the number one cause of serious,
long-term disability. Yet, studies show that nearly everyone can
become heart healthy by following a healthy diet and
participating in an appropriate exercise program; eliminating
tobacco products; and following a routine health care plan. Most
important to combating cardiovascular diseases as the number one
cause of disability and death is early detection and early
treatment.
