Function of the Heart The overall strength and health of the heart muscle
affects how well it pumps blood.
Function of the Heart This is accomplished by the heart muscle contracting,
The heart functions as a pump. It is called systole, and relaxing, called diastole. The

arterial circulation and removing the
waste products of metabolism via

What is heart failure? Impaired heart function; the ventricle is unable to
maintain a cardiac output sufficient to meet the
metabolic needs of the body
Heart failure/Pump failure, is the because it is a poor pump or there is poor filling
inability of the heart to function It does not allow adequate Cardiac output to meet
properly; the ventricles are not able the demands of the body which are blood, nutrients
to maintain cardiac output and oxygen.
We used to refer to Heart Failure as however we are trying to get away from using CHF
Congested Heart Failure because heart failure is more than just Congestion in
the heart as you will see in coming slides.
,Heart failure happens when the heart pump enough blood and oxygen to support other

Systole Contraction of the heart
Diastole relaxation phase of the heartbeat
systolic pressure Blood pressure in the arteries during contraction of
the ventricles.
diastolic pressure Blood pressure that remains between heart
contractions.

Preload/Afterload Preload affects the amount of blood going into Right
ventricle. Afterload is the systemic resistance after
leaving the heart.
Preload precontraction The precontraction pressure in the heart as the
volume of blood builds up.

Preload volume volume of blood in ventricles at end of diastole
Preload is increased in hypervolemia, regurgitation of cardiac valves, heart
