Coronary heart diseases

1. Coronary arteries and their function
• These are the vessels that
supply blood to heart
• These are very important
because they provide all the
nutrients to heart muscles
because the muscles are very
much strong and for their
proper contraction and
relaxation they need nutrients

2. Coronary heart
diseases
• Blockage of coronary
arteries is called
coronary heart
disease.
• It is the main cause of
illness and death
• It can cause heart
attacks, heart failure
and cardiac arrest

3. Risk factors for heart
diseases
• Smoking
• Diet irregularity
• Obesity
• Stress
• Inheritance
• Blood cholesterol level
• Age and physical inactivity
• High blood pressure
• Gender

5. Good and bad cholesterol
• LDL (low-density lipoprotein), sometimes
called “bad” cholesterol, makes up most
of your body’s cholesterol. High levels of
LDL cholesterol raise your risk for heart
disease and stroke.
• HDL (high-density lipoprotein), or
“good” cholesterol, absorbs cholesterol
and carries it back to the liver. The liver
then flushes it from the body. High levels
of HDL cholesterol can lower your risk for
heart disease and stroke.

6. How coronary heart
diseases are caused

7. Treatment of coronary heart
diseases
• Drug treatment with
aspirin
• Surgery ( stents ,
angioplasty , bypass)

8. Treatment by aspirin
• Aspirin, or acetylsalicylic
acid (ASA), is commonly used as
a pain reliever for minor aches
and pains and to reduce fever.
• It is also an anti-inflammatory
drug and can be used as a blood
thinner.
• People with a high risk of blood
clots, stroke, and heart attack
can use aspirin long-term in low
doses.

9. Stents
• This is a small mesh tube
called stent
• It is inserted into the
artery to keep it open

10. Angioplasty
• It involves usage of tiny
balloon
• Inserted into collapsed artery
• After this it is inflated using
water
• This pushes the artery open
• After this balloon is removed
• The process is called
angioplasty

13. Bypass surgery
• A blocked or severely
damaged artery can be
replaced with a length of
blood vessel taken from
another part of the body
• This is called bypass surgery
