Transcript of The heart
Cardiovascular Diseases and Conditions
The main function of the heart is to
pump your blood and to keep the
blood circulating though the body.
Myo- Muscle, Cardial- Heart
Infraction- Clog or blockage
Most often caused by a clot in the coronary artery, it blocks the supply of blood and oxgyen to the heart
Cardiovascular Risk Factors:
1. High Cholesterol
3. High Blood Pressure
7. Stress and Tension
8. Hereditary Lifestyle
Is the death of a body tissue.
It occurs when there is not enough blood flowing to the tissue, weather from injury radiation or chemicals.
Coronary Artery Disease
Coronary heart disease (CHD) is a disease in which a waxy substance called plaque builds up inside the coronary arteries.
These arteries supply oxygen-rich blood to your heart muscle.
CHD is the most common type of heart disease. In the United States, CHD is the #1 cause of death for both men and women.
Lifestyle changes, medicines, and medical procedures can help prevent or treat CHD. These treatments may reduce the risk of related health problems.
Supply blood to muscle tissue of the heart
What are the Coronary Arteries?
Angina- serve chest pain
Like the elephant on the chest
Nitroglycerin- used to help treat angina-
helps to widen blood vessels
Procedures-tests that are done to verify a suspected MI
Shows the electrical impulses of the heart
Contraction and relaxation of the heart
Drugs used to break up clots in the coronary artery.
Treat and prevent MI
Ex. Baby Aspirin
This is released when the heart feels it is in distress or damaged.
Follow up tests:
1. Stress Tests
2. Cardiac catheterization
3. Balloon Angioplasty
4.Open Heart surgery
5. Heart Transplant
-Help identify abnormal heart beat
- how the heart handles increasingly strenuous physical activity
Procedure where a small tube is inserted into the heart to look at its structure
A dye can be put in to show where the blockage in the coronary arteries are
Balloon is inflated in an artery pushing fatty deposits against the artery wall
Open Heart Surgery
Vein used to replace a blocked coronary artery
During this surgery, a healthy artery or vein is grafted (attached) to a blocked coronary (heart) artery. This allows the grafted artery to “bypass” the blocked artery and bring fresh blood to the heart.
Donor heart used to replace a sick heart
The most common reason is that one or both ventricles have aren't functioning properly and severe heart failure is present.
the force of blood against the walls of arteries.
Blood pressure is recorded as two numbers:
the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats)
High blood pressure is a common condition in which the force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.
How to measure:
Blood can't flow
Not flowing smoothly
Blood flow back to normal
