3. A heart attack occurs when the
flow of blood to the heart is
blocked.
The blockage is most often a
buildup of fat, cholesterol and
other substances, which form a
plaque in the arteries that feed the
heart (coronary arteries).
HEART ATTACK

4. A heart attack happens when
blood stops flowing to part of
your heart muscle.

5. A heart attack occurs
when one or more of
your coronary arteries
becomes blocked. Over
time, a buildup of fatty
deposits, including
cholesterol, form
substances called
plaques, which can
narrow the arteries
(atherosclerosis). This
condition, called
coronary
artery disease, causes
most heart attacks

6. The coronary
arteries are the
arterial blood
vessels of coronary
circulation, which
transport
oxygenated blood
to the heart
muscle. The heart
requires a
continuous supply
of oxygen to
function and
survive, much like
any other tissue or
organ of the body.
The coronary
arteries wrap
around the entire
heart.

7. HEART ATTACK / CARDIAC ARREST
A heart attack occurs
when a coronary
artery becomes
blocked, preventing
blood flow to part of
the heart muscle.
During a heart attack a
person remains
conscious and keeps
breathing.
A cardiac arrest
occurs when the
heart stops pumping
blood around the
body.
Normal breathing
stops and
consciousness is
lost.

8. Symptoms
• Chest pain – The chest may feel tight, pressured and heavy as if
it is being squeezed
• Pain in other areas – The pain may radiate to other parts of the
body such as the arms (usually the left arm), the neck, jaw, back
and abdomen
• Feeling dizzy or lightheaded
• Sweating
• Shortness of breath
• Nausea and vomiting
• Coughing or wheezing
• Severe anxiety that is often described as a sense of impending
doom
It is possible to have a 'silent' heart attack, where you
do not experience pain or where the only warning sign
may be an indigestion type of discomfort

9. Diagnosis
• An ELECTROCARDIOGRAPH (ECG) test shows any
changes in the electrical activity of your heart.
• BLOOD TESTS can show higher levels of certain proteins or
enzymes made during a heart attack.
• ECHOCARDIOGRAPHY TEST imaging test can be used
during and after a heart attack to learn how your heart is
pumping and what areas aren’t pumping the way they should.

10. • AVOID TRANS FATS AND SATURATED FATS WHENEVER
POSSIBLE. These fats directly contribute to plaque formation in the arteries.
When your arteries become clogged, blood can no longer flow to the heart,
resulting in a heart attack. Instead, eat fats that come from plant sources, such
as olive oil or nuts.
• EAT FEWER CALORIES. Eating too many calories and having overweight
can also strain your heart. Managing your weight and eating a balance of
plant foods, lean meats, and low-fat dairy products can help.
DIET
A low-fat, low-calorie diet has been
proven to help prevent the risk of a
heart attack
• LIMIT SODIUM. Reducing your daily sodium intake to under 2,300 mg per
day can decrease blood pressure and the overall strain on your heart.
• FOCUS ON EATING PRODUCE. Whole, fresh fruits and vegetables should
be staples in your diet. When fresh produce isn’t available, consider
substituting with no-sugar-added frozen or salt-free canned versions.
