2. Why Study Coronary Heart
Disease?
Coronary heart disease is a major factor
Leading cause of death in the United States claiming
370,000 lives annually.
Easily preventable and controllable through health
education on healthy eating habits and physical activity
to reduce the risk factors.
Important because there is a high rate of coronary heart
disease in underserved communities
Most prevalent among residents of underserved
communities, with habits originating during childhood
Educate communities to limit risk factors.
3. Overview
Coronary heart disease (CHD) is a narrowing of the small blood vessels that supply
blood and oxygen to the heart.
Alternative name of coronary heart disease: Heart disease, Coronary heart disease,
Coronary artery disease; Arteriosclerotic heart disease; CHD; CAD
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.
4. History of Coronary Hearth
Diseases
The earliest date for the medical communities awareness of coronary
heart disease and arteries narrowing is unknown.
- Leonardo da Vinci (1452–1519) investigated coronary arteries.
- William Harvey (1578–1657) is credited with discovering how the blood
moves: from the right ventricle of the heart through the lung and into the
aorta, then the peripheral vessels, and back into the lung.
- Subsequently, Friedrich Hoffmann (1660–1742), chief professor of
cardiology at the University of Halle, noted that coronary heart disease
started in the “reduced passage of the blood within the coronary
arteries.”

7. CauseOf TheCoronary Heart Diseases.
Coronary heart disease is caused by the
buildup of plaque in the arteries to your
heart.
Fatty material and other substances form
a plaque buildup on the walls of coronary
arteries. The coronary arteries bring blood
and oxygen to the heart.
This buildup causes the arteries to
narrow
As a result, blood flow to the heart can
slow down or stop which may lead to the
risks factors.
Working hard to eliminate the risk factors
can save lives.

9. What aretheSymptomsOf Heart
Diseases?
Symptoms may be very noticeable, or alternatively
imperceptible. Hearth disease is often asymptomatic in
its early stages.
Chest pain or discomfort (angina) is the most
common symptom. Affected individuals feel pain when
the heart is not getting enough blood or
oxygen. Though the pain intensity varies.
Manifestation of this pain includes:
Sensation if someone is squeezing ones heart. Often
noticeable under ones breast bone (sternum). Pain also
may radiate to the neck, arms, stomach, or upper back.
The pain most often occurs with activity or emotion.
It goes away with rest or a medicine called nitroglycerin.
Other symptoms include shortness of breath and
fatigue with activity (exertion).
Some people have symptoms other than chest pain,
such as: Fatigue, Shortness of breath, General weakness
