CHRONIC DISEASES
Chronic Diseases are diseases that persist for a long period of time or reoccur throughout life. Chronic Diseases
are caused by behavioral factors, environmental factors or heredity. These diseases are also the leading cause of
death in the United States.
CARDIOVASCULAR
DISEASES
HYPERTENSION
DESCRIPTION
 Also known as ______________________ and is a silent killer!
 Normal blood pressure is 120/80. A person whose blood pressure consistently
measures __________ or higher has hypertension.
 Hypertension can lead to heart disease or death.
 ______________, ______________, ______________, eating foods low in sodium will
reduce your risk of hypertension.
ATHEROSCLEROISIS
 Also known as ______________________.
 A disease where fatty substances called _____________ build up in your __________.
 The buildup makes blood flow difficult, so your blood pressure rises.
HEART ATTACK
 Occurs when the tissue in your _____________ doesn’t receive normal blood supply.
 Usually caused by a _________________ that blocks the flow of blood to the heart.
 Each year, over a _________________ people in the United States suffer from heart
attacks and about _________________ of those million people will die because of the
heart attack.
 Also known as _________________ .
 Heart can either beat too slow or too fast.
 Fibrillation is a life-threatening arrhythmia is which the heart twitches rapidly in an
uncontrolled fashion. Some of these can be controlled by medicines others require
surgery and artificial pacemakers.
ARRHYTHMIA
CONGESTIVE HEART
FAILURE
 Sudden disruption of _________________ to the brain.
 Usually caused by a _________________ blocking an artery to the brain.
 Strokes can also occur when a weakened artery in the brain bursts, flooding the
area with blood. Without a supply of blood, brain cells soon die from lack of oxygen.
 Risk factors for stroke include high blood pressure, high cholesterol, smoking,
excessive use of alcohol, physical inactivity, and obesity.
STROKE
UNIT 7
 The heart slowly _________________ over time.
 Usually caused by years of arthrosclerosis and high blood pressure.
 The _________________ is unable to pump blood like it once did.

TESTING AND TREATMENT OF CARDIOVASCULAR DISEASES

Cardiovascular disease CANNOT be cured, but can be controlled. Below are some of the medical technologies
used to test for cardiovascular disease and the treatment methods used to treat and improve a person’s health.
TESTING FOR CARDIOVASCULAR DISEASE (page 606)
_______________________________: A device that generates __________________ is placed against the chest. The sound
waves create a moving picture of the ________. A doctor can evaluate the heart’s valves and chambers from the picture.
_______________________________: Electrodes attached to the skin detect the heart’s _________________. Abnormalities
in __________________ or other heart problems are revealed in the recorded pattern.
_______________________________: A flexible tube is threaded through an artery in an arm or leg until it reaches the
heart. A dye is then released in to the ________________, and X-rays are taken. The ________________ can reveal
blockages.
_______________________________: Magnetic energy is used to produce a clear image of the heart. Doctors can analyze
the image for damage.
TREATMENT FOR CARDIOVASCULAR DISEASE (page 606)
_______________________________: Surgeons use a ____________ from the patient’s leg or an artificial blood vessel to
construct a detour around a ____________ coronary artery. This procedure creates an alternate route for blood flow.
_______________________________: When a person’s heart cannot function adequately, it may be replaced with a heart
from an organ ____________. This surgical procedure carries some risk because the ____________ system may reject
the new heart. To lower rejection rates, doctors use drugs to suppress the immune system.
_______________________________: A thin tube with an expandable tip is guided into a coronary artery. As the tip is
inflated, it flattens fatty deposits in the artery wall, improving ___________________. Metal structures called stents are
some-times inserted to keep the artery open.
_______________________________: An artificial pacemaker is a small, battery operated device that is surgically
implanted in the chest. It produces electrical impulses that regulate the heartbeat.

1. In 2010, were there more incidences of breast cancer or prostate cancer? ____________________
2. Since 2005, have the incidences of breast and prostate cancer increased or decreased? _________
Why do you think this happened? _________________________________________________________
3. Prostate cancer kills more men every year then breast cancer kills women, why do you think this
is? ___________________________________________________________________________________
How Cancer Affects the Body
 Cancer is a group of diseases that involves the rapid, uncontrolled growth and spread of
_____________________.
 Cancer harms the body by destroying _______________________ body tissue.
 Cancer cells typically form a mass called a _____________________.
 Tumors can be either malignant or benign.
o _____________________ means the tumor IS cancerous.
o _____________________ means the tumor IS NOT cancerous.
 Cancer cells can travel in the blood stream and travel to other parts of the body and this is called
__________________.
 Many cancers can be treated if caught early.

Unusual bleeding or discharge
Thickening or Lumps
Indigestion or difficulty swallowing
Obvious change in a wart or mole
Nagging cough or hoarseness
Cancer Treatment
SURGERY – can remove part or the entire tumor either malignant or benign.
RADIATION THERAPY – can kill cancer cells and slow tumor growth by using an external source that
supplies the radiation either directly or indirectly to the tumor.
CHEMOTHERAPY – uses drugs to slow the reproduction of cancer cells. Immunotherapy uses drugs to stimulate the
body’s immune system to attack cancer cells.
