Pathways to Equality: The Role of Men and Women in Gender Equity
Circulatory disorder heart attack
1.
2. Heart – pumps blood in body
Blood – carries important oxygen, food, & waste
through body
Blood Vessels - routes blood travels
3. • Our heart is a
muscular organ
that acts like a
pump to send
blood
throughout our
body all the
time.
4. •The complete round of cardiac
systole and diastole with the
intervals between, or commencing
with, any event in the hearts
action to the moment when that
same event is repeated.
•.The frequency of the cardiac
cycle is the heart rate.
5. There are 4 chambers -
• 2 upper chambers : Left Atrium
Right Atrium
• 2 lower chambers : Left Ventricle
Right Ventricle
6.
7. Lub
If you listen to
your heartbeat, it
makes a lub dub
sound.
The lub is when blood
is pushed out of the
heart into the body and
the dub is the
reloading of the heart
with more blood ready
to push it out to the
body
Dub
8. •Blood with little oxygen is pumped from the Right
Atrium through a valve to the Right Ventricle and
through another valve into the Pulmonary Vein. The
Pulmonary Vein sends it to the Lungs to pick up
Oxygen.
•It’s sent from the Lungs through Pulmonary Arteries
to the Left Atrium through a valve to the Left
Ventricle.
•The Left Ventricle sends it through a valve to the
Aorta.

10. Coronary Artery Disease
• Coronary artery disease is one of the most common
and serious effects of aging. Fatty deposits build up
in blood vessel walls and narrow the passageway for
the movement of blood. The resulting condition,
called atherosclerosis often leads to eventual
blockage of the coronary arteries and a “heart
attack”.
11. • None:. Blood to your heart
may be restricted due to
CAD, but you don’t feel any
effects.
• Chest pain: If your coronary
arteries can’t supply enough
blood to meet the oxygen
demands of your heart, the
result may be chest pain
called angina.
• Heart attack: Results when
an artery to your heart
muscle becomes completely
blocked

15. • Many people are able to manage
coronary artery disease with lifestyle
changes and medications.
• Other people with severe coronary
artery disease may need angioplasty or
surgery.
16.
17. Treatment
1) Stenting
• a stent is introduced into a blood vessel on a balloon
into the blocked area of the artery.
• the balloon is then inflated and causes the stent to
expand until it fits the inner wall of the vessel,
conforming to contours as needed
• the balloon is then deflated and drawn back
•The stent stays in place permanently, holding the
vessel open and improving the flow of blood.
18. Treatment
2) Angioplasty
• a balloon is passed through the guiding catheter to the area near
the narrowing.
• the angioplasty catheter is moved over the guide wire until the
balloon is within the narrowed segment.
• balloon is inflated, compressing the plaque against the artery wall
• once plaque has been compressed and the artery has been
sufficiently opened, the balloon catheter will be deflated and
removed.
19. Treatment
3) Bypass surgery
• healthy blood vessel is removed from leg, arm or chest
• blood vessel is used to create new blood flow path in your heart
• the “bypass graft” enables blood to reach your heart by flowing
around (bypassing)
the blocked portion
of the diseased
artery. The
increased blood
flow reduces angina
and the risk of heart
attack.
20. • Heart transplants are done
as a life-saving measure for
end-stage heart failure when
medical treatment and less
drastic surgery have failed.
They need to be sick enough
to need a new heart, yet
healthy enough to receive it.
21.
22. •Hypertension, also referred to as high blood
pressure, HTN or HPN, is a medical condition
in which the blood pressure chronically
elevated.
•Persistent hypertension is one of the risk
factors for strokes and heart attacks.
23. 1. Heart has to work harder; left ventricle
enlarges
2. Atherosclerosis may affect coronary
arteries as well (which have to work harder
anyway)→ heart disease
3. Deficient blood supply to other parts of body
damage to blood vessels accumulates
heart failure
25. •A heart attack occurs when
blood flow to a section of heart
muscle becomes blocked. If the
flow of blood isn’t restored
quickly, the section of heart
muscle becomes damaged from
lack of oxygen and begins to die.
.
26. •Severe problems linked to heart
attack can include heart failure and
life-threatening arrhythmias (irregular
heartbeats).
•A defibrillator is used to restart the
pumping of the blood after a cardiac
arrest by giving the patient electric
shocks ranging from 200-300 joules.

28. •Get regular medical checkups.
•Control your blood pressure.
•Check your cholesterol.
•Don’t smoke.
•Exercise regularly.
•Eat a heart-healthy diet.
•Manage stress.
29. • Heart is one of the vital organs in the
human body.
• Heart attack can happen to anyone
even if you are healthy.
• Obesity, high blood pressure and high
cholesterol can increase the risk of
developing heart disease .
30. The Difference Between a Heart
Attack, Stroke, and Cardiac Arrest
• Heart Attack
A heart attack happens when one of the
main arteries of the heart gets blocked,
causing the heart to not get enough blood
flow,”.
• Stroke
• There are two major types of strokes:
ischemic and hemorrhagic. Ischemic is
where a blood clot cuts off the supply of
blood to an area of the brain.
31. The Difference Between a Heart Attack,
Stroke, and Cardiac Arrest
Cardiac Arrest.
Cardiac arrest, on the other hand,
happens when the heart stops completely
or has a dangerous rhythm, she says.
Cardiac arrests can sometimes be caused
by heart attacks,
