What is the primary goal ensure adequate cardiac output for proper perfusion
of normal heart function? of tissue/organs
What 3 factors influence preload, afterload and contractility
the stroke volume?
pathophysiologic condition when the heart is unable
to generate adequate cardiac output/ pump enough
What is Heart Failure? blood to meet the body's metabolic needs
- inadequate circulatory volume & pressure
- results in inadequate perfusion of tissue
What are the 2 types of - systemic: left side to body

programs
Left side
-because blood accumulates in the LV --> LV
Which side is HF more
hypertrophies to compensate for the increased
common on and why?
preload (extra blood in the chamber)
-because HTN affects it (75% of HF cases)
To eliminate excess fluid
Why do you cough with
- If LV is weakened/failing, bld goes backwards and
left sided HF?
fluid builds up in the lungs
