✓ Cardiomyopathy⟶ viral, postpartum, substance abuse (cocaine, meth, stimulants)
✓ Valvular heart disease

Frank-Starling law:

✓ the more myocardial fibers stretched the greater contraction⟶ like a rubber band, and
can also be stretched too far


Ejection Fraction (EF):

✓ % of blood forced out of the left ventricle w/ each beat


normal EF

✓ 55-60%


if EF is good but have HF symptoms, what kind of HF is it?

✓ diastolic HF


Mean arterial pressure (MAP):
