Heart Attack Vs Stroke: What Is The Difference?
It is important to know the differences between heart attack and stroke because many people think that they are similar. Heart attack and stroke develop from blockages in the blood vessels but the difference is that they affect different critical functions of the body.
The symptoms of heart attack and stroke also differ. Heart attack starts with chest pain and the latter one starts with a sudden and powerful headache.
The symptoms of stroke and heart attack depend on the severity of the episode, your age, your overall health and your gender. Discussed here is the difference between a heart attack and stroke.
Heart Attack
A heart attack occurs when a sudden damage happens to the heart muscles usually from the lack of blood flow in the coronary artery. The blocked coronary artery then prevents the oxygen from getting to the muscle tissues of the heart.
Most
of
the
time,
blood
clots
form
in
the
coronary
arteries
thereby
blocking
the
blood
flow
to
the
heart
muscle
which
leads
to
chest
pain
and
other
heart
attack
symptoms.
Heart
attacks
can
result
in
permanent
damage
to
the
heart
muscle
and
cause
the
death
of
the
person.
Stroke
A stroke occurs when there is a formation of blood clot in the arteries that supply blood to the brain. The brain tissues become deprived of oxygen leading to damage or death of the brain tissue. A stroke is often associated with losing the ability to move which affects only one side of the body.
Strokes
come
in
three
forms
which
include:
1.
Bleeding
in
the
brain
which
is
called
a
haemorrhagic
stroke.
2.
A
stroke
caused
by
a
blood
clot
is
known
as
ischemic
stroke.
3.
Narrowing
of
an
artery
that
feeds
blood
to
the
brain
is
called
a
transient
ischemic
attack.

levels

Diagnosis Of Heart Attack And Stroke
In the case of stroke, your doctor will ask about the symptoms and medical history, followed by a CT scan of the brain. The CT scan shows the areas of the brain that have been affected by poor blood flow or if there is any bleeding. An MRI of the brain is also done.
To diagnose a heart attack, a different set of tests are done. But first, your doctor will examine your symptoms and medical history. Then, an electrocardiogram is done to check on the health of the heart muscle. To check for enzymes that indicate a heart attack, a blood test is done. To check for blockages in the blood vessels into the heart, a cardiac catheterization is done by inserting a long, flexible tube through the blood vessel.
How Are Heart Attack And Stroke Treated?
Heart attack treatment
The emergency treatment for heart attack is cardiopulmonary resuscitation which is done when the patient has no pulse. To open blocked arteries, clot-busting medications are given to the patients. Also, sometimes treating the blockage responsible for a heart attack may require emergency coronary artery bypass grafting. It is a surgery where segments of blocked heart arteries are removed and is replaced with open vessels taken from other areas of the body.
Stroke treatment
If the patient has a haemorrhagic stroke, he/she may need surgery to repair the damaged blood vessels. Or if the patient has an ischemic stroke and made it to the hospital within a few minutes of the symptoms starting, the doctor may give a medication called tissue plasminogen activator which helps to break a clot.
Steps To Be Taken To Prevent Heart Attack And Stroke
Taking the same preventive methods can help prevent strokes and heart attack which include:
1.
Checking
your
cholesterol
and
blood
pressure
levels
on
a
regular
basis.
2.
Avoiding
smoking.
3.
Maintaining
a
healthy
weight.
4.
Limiting
the
intake
of
alcohol.
5.
Keeping
your
blood
sugar
under
control.
6.
Doing
moderate
exercises.
7.
Following
a
diet
that
is
low
in
saturated
fat,
sodium
and
added
sugars.
