Heart Attack Symptoms and its Causes
2
A heart attack happens when there is a sudden
complete blockage of an artery that supplies
blood to an area of your heart. A heart is a
muscle, and it needs a good blood supply to keep
it healthy. As we get older, the smooth inner
walls of the arteries that supply the blood to
the heart can become damaged and narrow due to
the build up of fatty materials, called plaque.

Causes of heart Attack
The underlying cause of a heart attack
is coronary heart disease.  Some people may not
know they have coronary heart disease until they
have a heart attack. For others, a heart attack
can happen after weeks, months or years of having
coronary heart disease.

Sign and its Symptoms
Heart Attack
Heart attack symptoms vary. Not all heart attacks
begin with a sudden, . The warning signs and
symptoms of a heart attack arent the same for
everyone. Many heart attacks start slowly as mild
pain or discomfort. Some people dont have
symptoms at all (this is called a silent heart
attack).

areas in the area between shoulder blades, arm,
chest, jaw, left arm, or upper abdomen. Pain

Diagnosis
If you are rushed to hospital with a suspected
heart attack, your health care team will do some
tests to find out if you are having a heart
attack. They may include electrocardiogram (ECG)
, Blood tests
chest X-ray
coronary angiogram.

How is a heart attack
treated? When you arrive at hospital you will
receive treatment for your blocked artery. Either
you will have a Primary Percutaneous Coronary
Intervention (PPCI) which is an
emergency coronary angioplasty. It involves
reopening your blocked coronary artery, restoring
the blood supply to the part of your heart that
is starved of blood, which helps to save as much
of your heart muscle as possible. Or you will
have Thrombolysis, also called a clot buster.
This involves injecting a medicine into a vein to
dissolve the blood clot and restore the blood
supply to your heart. Sometimes this may be given
to you in the ambulance. In some types of heart
attack people do not receive either of these two
treatments because they will not benefit from
them.

Heart attack prevention
Living a healthy lifestyle can help prevent you
from developing coronary heart disease and having
a heart attack. If you have had a heart attack
you can dramatically reduce the risk of having
another heart attack and future heart problems
by keeping your heart healthy and taking your
medicines. If you're over 40 you should ask your
doctor or nurse for a heart health check to
assess your risk of having a heart attack in the
next 10 years.

What about recovery?
A heart attack can be a frightening experience
and it can take time to come to terms with what
has happened. It's natural to be worried about
your recovery and future. Many people make a full
recovery and within a few months are able to
return to their normal activities.  However some
people may find that they are not able to do as
much as they previously did. Attending a cardiac
rehabilitation course will increase your chances
of getting back to normal as quickly as possible.
