 arteriosclerosis
A group of disorders 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
 heart attack
A serious condition that occurs when the blood
supply to the heart slows or stops and the
heart muscle is damaged
 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
 stroke
A serious condition that occurs when an artery of
the brain breaks or becomes blocked
 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 the blockage
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.
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
have other unhealthy habits like poor diet
are more at risk for developing heart disease.
Types of Coronary Heart Disease
The heart is a muscle
that pumps blood
through the body.
The coronary arteries
Bring blood to the heart
From the lungs
Oxygen Rich
If the coronary
arteries are clear,
blood flows freely.
Coronary arteries on
the surface of the heart
supply it with
oxygen-rich blood.
Veins on the heart
take oxygen-poor
blood away.
If the coronary
arteries are blocked,
coronary disease
begins to develop.
A healthy
coronary artery
Is free of fatty
substances
Blood can flow
through
An unhealthy
coronary artery
has a buildup of
fatty
substances that
partially block
the flow of
blood
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.
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.
A Heart Attack
Symptoms of a Heart Attack
for Males
Symptoms of a Heart Attack
for Females
Pain or pressure in the chest
Similar to males, but more likely
than males to experience
shortness of breath, nausea, and
pain in their back jaw.
Pain in the arms, jaw, back or
abdomen
Shortness of breath
Shortness of breath
Cold skin
Nausea
Passing out
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
stroke A serious condition that occurs when an artery of the brain
breaks or becomes blocked
Other Problems of the Circulatory System
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.
Preventing Heart Disease
Eat healthful foods.
Limit cholesterol,
trans fats, and saturated fats.
Manage stress.
Participate in regular
physical activity.
Stay tobacco free.
Maintain a healthy weight.
Stay alcohol free.
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
Treating Heart Disease
Other methods used to treat heart disease are:
Medications
Pacemakers
Bypass surgery
Heart transplants
