Only men suffer from Heart Failure.
Over 50% of sufferers are women.
How many people are affected with Heart Failure?
5 million (2x a decade ago)
How many people die each year of Heart Failure?
How much money is spent on health care of patients with Heart Failure?
Hint: in the diagram, look at the direction of blood flow and how the valves close

Right side pumps venous blood into lungs, which drains into left side of heart for pumping oxygenated blood to the brain and body.
Cause: heart arteries get filled with deposits (“plaques”) that promote clots that block the artery. See artery cross section below:
narrowed opening for blood flow
The heart needs blood and oxygen too!!
When one of these arteries gets blocked, a heart attack can occur
The inability of the heart to pump enough blood to the rest of the body.
Why do you suppose it is called CONGESTIVE heart failure?
Some of the symptoms of heart failure are related to
Arrows indicate the presence of fluid in the lungs
(>140-160 mmHg or >90 diastolic, or both) seen in 91% of people with CHF
*** Both women and men are at risk, especially if they have any of the above risk factors
Tendon-like cords connect valves (underside at top) to walls of the heart and help hold the valves shut during contraction
Small white ring is an artificial valve that is being lowered into heart.
Patent: to make open
Ductus: tube or canal
Arterio: relating to an artery
Put the words together to see that it means there is an artery that is open (that should be closed!)
It is an artery that needs to be open in the fetus but needs to be closed in the adultPatent Ductus Arteriosus (PDA)
After birth: blood must go through lungs
Fetus: shunt bypasses lungs
