Coronary heart disease is caused by plaque buildup in the coronary arteries that supply blood to the heart. Over many years, plaque narrows the arteries and reduces blood flow. If plaque ruptures, a blood clot can block blood flow and cause a heart attack. A heart attack occurs when an area of the heart muscle dies from lack of oxygen-rich blood. Angina is chest pain that occurs when blood flow to the heart is reduced. Coronary heart disease is the leading cause of death in the United States and lifestyle changes, medicines, and procedures can help prevent and treat it.

Coronary heart disease
1. Coronary Heart Disease
(CHD)
What Is Coronary Heart 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.
When plaque builds up in the arteries, the
condition is called atherosclerosis. The
buildup of plaque occurs over many years.
3. • Over time, plaque can harden or rupture.
Hardened plaque narrows the coronary
arteries and reduces the flow of oxygenrich blood to the heart.
• If the plaque ruptures, a blood clot can
form on its surface. A large blood clot can
mostly or completely block blood flow
through a coronary artery. Over time,
ruptured plaque also hardens and narrows
the coronary arteries.
• If the flow of oxygen-rich blood to your
heart muscle is reduced or blocked, angina
or a infarct can occur.
4. Angina
Angina is chest pain or discomfort. It may feel like
pressure or squeezing in your chest. The pain also
can occur in your shoulders, arms, neck, jaw, or
back. Angina pain may even feel like indigestion.
Infarct
A infarct occurs if the flow of oxygen-rich blood to a
section of heart muscle is cut off. If blood flow isn’t
restored quickly, the section of heart muscle begins
to die. Without quick treatment, a infarct can lead to
serious health problems or death.
5. How to cure?
• 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.
6. Ictus
• Is the interruption, temporary or permanent,
the blood supply to part of the brain that
appear suddenly.
When blood flow ceases to reach any area of
the brain, may alter the functions of this area
• Has come to be considered one of the
leading causes of death in developed
countries. In fact, in women is the first cause,
and in males the second, behind the infarct.
