2. A group of disorders that cause a thickening and hardening of the arteries
arteriosclerosis
A condition that occurs when fatty substances build up on the inner lining of the arteries
atherosclerosis

A serious condition that occurs when the blood supply to the heart slows or stops and the heart muscle is damaged
heart attack

3. A disease in which the pressure of the blood on the walls of the blood vessels stays at a level that is higher than normal
hypertension
A serious condition that occurs when an artery of the brain breaks or becomes blocked
stroke

A surgical procedure in which an instrument with a tiny balloon, drill bit, or laser attached is inserted into a blocked artery to clear the blockage
angioplasty

4. In this lesson, you will learn to
identify types of heart disease.
explain how to reduce the risk of heart disease.
describe how heart disease is treated.
analyze the influences of food advertising on heart health.
explain how strokes and hypertension are related to heart disease.

5. What Is Cardiovascular Disease?
Cardiovascular or heart disease is any condition that reduces the strength of the heart and blood vessels.
Sometimes, heart disease is due to heredity, but it is usually related to lifestyle.
People who smoke, get very little exercise, or have other unhealthy habits are more at risk for developing heart disease.
People who
Smoke
get very little exercise
have other unhealthy habits like poor diet
are more at risk for developing heart disease.

6. Types of Coronary Heart Disease
The coronary arteries
Bring blood to the heart
From the lungs
Oxygen Rich
Types of Coronary Heart Disease
The heart is a muscle that pumps blood through the body.
If the coronary arteries are clear, blood flows freely.
A healthy coronary artery
Is free of fatty substances
Blood can flow through
Coronary arteries on the surface of the heart supply it with oxygen-rich blood.
If the coronary arteries are blocked, coronary disease begins to develop.
An unhealthy coronary artery has a buildup of fatty substances that partially block the flow of blood
Because the heart is a muscle, it needs oxygen just like all your other organs.
Veins on the heart take oxygen-poor blood away.

7. Types of Coronary Heart Disease
Arteriosclerosis is a group of disorders that includes atherosclerosis.
arteriosclerosis A group of diseases that cause a thickening and hardening of the arteries
atherosclerosis A condition that occurs when fatty substances build up on the inner lining of the arteries
When buildup collects inside the arteries, it takes up space needed for blood to flow through.
If the coronary arteries become blocked with too much buildup, the heart may not get enough oxygen.
When buildup collects inside the arteries,
it takes up space needed for blood to flow through.
If the coronary arteries become blocked with too much buildup,
the heart may not get enough oxygen.

8. A Heart Attack
A heart attack can happen if the heart does not get enough oxygen from the blood.
heart attack A serious condition that occurs when the blood supply to the heart slows or stops and the heart muscle is damaged.

9. A Heart Attack Symptoms of a Heart Attack for Males
Chest pain/pressure
Upper body pain – arms, left shoulder, jaw, stomach
Rapid or irregular heart beat
Upset stomach – indigestion, nausea or vomiting
Shortness of breath –even your resting
Dizziness, light headedness or fainting
Confusion, severe anxiety
Cold sweat
Each heart attack is different. Trust your instincts if you
think something is wrong get help.

10. A Heart Attack Symptoms of a Heart Attack for Females
Heart attack symptoms can be quiet different for women
than for men.
Many times a women’s symptoms do not include chest
pain.
Sometimes they just don’t feel good
80% of the time women experience at least one
symptom for more than a month before their heart attack

11. A Heart Attack Symptoms of a Heart Attack for Females
Unusual fatigue lasting for several days or sudden
severe fatigue
Sleep disturbances
Anxiety
Lightheadedness
Shortness of breath
Indigestion or gas like pain
Pain – upper back, shoulder, throat, jaw, stomach
Pressure or pain in center of chest which may spread
to arm
Rapid or irregular heart beat
Sweating

12. Other Problems of the Circulatory System
Hypertension can lead to a heart attack or a stroke.
hypertension A disease in which the pressure of the blood on the walls of the blood vessels stays at a level that is higher than normal
Hypertension:
People who have hypertension can manage the condition by following a healthful eating plan, exercising regularly, avoiding stress, and taking medicine if needed.
Stroke:
Like the heart, the brain needs plenty of oxygen and nutrients to function.
If an artery leaks or develops a thick mass called a clot, blood flow to the part of the brain is interrupted, causing damage.
The effects of a stroke depend on what part of the brain is affected.
stroke A serious condition that occurs when an artery of the brain breaks or becomes blocked

14. Preventing Heart Disease
Eat healthful foods.
Limit cholesterol, trans fats, and saturated fats.
Manage stress.
Participate in regular physical activity.
Stay tobacco free.
Eat healthful foods:
Choose plenty of fresh fruits and vegetables, whole grains, and lean sources or proteins.
Limit cholesterol, trans fats, and saturated fats:
These foods are linked to cardiovascular disease.
Participate in regular physical activity:
Physical activity makes your heart stronger.
Maintain a healthy weight:
Your heart works best if your weight is within a healthy range.
Manage stress:
Stress contributes to hypertension.
Stay tobacco free:
Chemicals can cause heart disease, heart attacks, hypertension, and strokes.
Stay alcohol free:
Alcohol has been linked to high blood pressure and heart failure.
Maintain a healthy weight.
Stay alcohol free.

15. Treating Heart Disease
Angioplasty is a popular method for treating heart disease.
angioplasty A surgical procedure in which an instrument with a tiny balloon, drill bit, or laser attached is inserted into a blocked artery to clear a blockage
With the balloon method, doctors inflate the balloon which then crushes the blockage against the artery walls. Lasers or drill bits are used to cut or burn away the blockage.

16. Treating Heart Disease
Other methods used to treat heart disease are:
Medications
Pacemakers
Bypass surgery
Heart transplants
Medications:
Medications can break up blood clots. Aspirin can dissolve blood clots and keep new ones from forming. Drugs that cholesterol levels also help fight heart disease.
Pacemakers:
Pacemakers and implantable defibrillators are electronic devices inside a person’s chest. A pacemaker sends out electrical signals that help the heart beat regularly.
Bypass surgery:
Bypass surgery creates new pathways for blood to flow around blockages. Surgeons can take a healthy blood vessel from another part of the body and set up a new route for blood to flow around the blockage.
Heart transplants:
Heart transplants completely replace a damaged heart with the healthy heart of someone who has just died.
