Cardiogenic Shock
either systolic or
diastolic dysfx of
the ♡'s pumping
action results in
⇓ CO(⇓ 4L/min)
⇓filling results in
⇓ SV
CO=SV X HR
systolic dysfx:
heart's inability
to pump the blood
forward
primarily affects
the LV
Most common
cause: MI
Leading cause of
death from MI

Signs of peripheral
