• The oxygenated blood is pumped to the body to provide oxygen and nutrients and to remove waste products.
• The coronary arteries are the blood vessels that supply blood and oxygen to the heart muscle.
“Cardiovascular disease (CVD) claimed 39.4 percent of all deaths or 1 of every 2.5 deaths in the United States in 2000. CVD was about 60 percent of “total mention mortality.” This means that of over 2,400,000 deaths from all causes, CVD was listed as a primary or contributing cause on about 1,415,000 death certificates.” (American Heart Disease)

•Since 1900, CVD has been the No. 1 killer in the United States every year but 1918. •Nearly 2,600 Americans die of CVD each day, an average of 1 death every 33 seconds. •CVD claims more lives each year than the next 5 leading causes of death combined, which are cancer, chronic lower respiratory diseases, accidents, diabetes mellitus, influenza and pneumonia. •Almost 150,000 Americans killed by CVD each year are under age 65.

Blood Supply To The Heart
Two coronary arteries branch from the main aorta just above the aortic valve. “No larger than drinking straws, they divide and encircle the heart to cover its surface with a lacy network that reminded physicians of a slightly crooked crown (coronary comes from the Latin coronarius, belonging to a crown or wreath). They carry out about 130 gallons of blood through the heart muscle daily.”
