Presentation transcript:

The function of the heart is to circulate blood throughout the body by: Pumping blood through the lungs removes carbon dioxide and refreshes the blood with oxygen 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. (Heart muscle cannot get oxygen and nutrients from the blood inside the chambers!)

2 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 to the heart muscle daily.” (Clark, 119) Blood Supply To The Heart

Cardiovascular Disease (CVD) Estimates for the year 2005 are that 80,700,000 people in the United States have one or more forms of cardiovascular disease (CVD). –High blood pressure — 73,000,000. –Coronary heart disease — 16,000,000. –Stroke — 5,800,000. –Heart Failure — 5,300,000

Cardiovascular Disease claimed 869,724 lives in 2004 (36.3 percent of all deaths or 1 of every 2.8 deaths).

Since 1900, CVD has been the No. 1 killer in the United States every year but 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.

Coronary Artery Disease Coronary artery disease is one of the most common and serious effects of aging. Fatty deposits (cholesterol) build up in blood vessel walls (plaques) and narrow the passageway for the movement of blood. The resulting condition, called atherosclerosis often leads to eventual blockage of the coronary arteries and a “heart attack” (myocardial infarction)

can, and does, occur in almost any artery in the body. But in the heart it’s effects can be crucial. “The body depends on a strong pumping heart to circulate life-giving blood, and this includes to the heart muscle itself. If the coronary arteries become blocked, the cardiac muscle begins to fail, and so the blood circulation decreases, which includes the circulation to the heart muscle itself.” (Thibodeau, 494)

Blood tests: used to evaluate kidney and thyroid function as well as to check cholesterol levels and the presence of anemia. Chest X-ray: shows the size of your heart and whether there is fluid build up around the heart and lungs. Echocardiogram: shows a graphic outline of the heart’s movement Ejection fraction (EF): determines how well your heart pumps with each beat.

Many people are able to manage coronary artery disease with lifestyle changes and medications. Other people with severe coronary artery disease may need angioplasty or surgery.

Treatment (continued) 1) Angioplasty a balloon catheter is passed through the guiding catheter to the area near the narrowing. A guide wire inside the balloon catheter is then advanced through the artery until the tip is beyond the narrowing. the angioplasty catheter is moved over the guide wire until the balloon is within the narrowed segment.

balloon is inflated, compressing the plaque against the artery wall once plaque has been compressed and the artery has been sufficiently opened, the balloon catheter will be deflated and removed.

Treatment (continued) 2) Stenting a stent is introduced into a blood vessel on a balloon catheter and advanced into the blocked area of the artery the balloon is then inflated and causes the stent to expand until it fits the inner wall of the vessel, conforming to contours as needed

the balloon is then deflated and drawn back The stent stays in place permanently, holding the vessel open and improving the flow of blood.

Treatment (continued) 3) Bypass surgery In a coronary bypass, surgeons often graft a leg vein from a coronary artery to the aorta so that blood flow can circumvent the blocked or narrowed vessel

Get regular medical checkups. Control your blood pressure. Check your cholesterol. Don’t smoke. Exercise regularly. Maintain a healthy weight. Eat a heart-healthy diet. Manage stress.
