-MAP would be normal because the Left Ventricle is intact




-physical exam findings: JVD, pedal edema, hepatomegaly due to venous backup




Left Heart Failure

 -↑ PCWP (L heart)



-Decreased LV function leads to pulmonary congestion (↑ PCWP)




-↓ MAP




- Physical exam findings: Crackles due to backup of fluid in the lungs




Right & Left Heart Failure (combined)

 - ↑CVP & ↑ PCWP


-CHF with both ventricles or left ventricle pumping poorly will cause a backup in the

pulmonary system and may back up on the right side as well = which will elevate CVP &

PCWP




-CO/CI & BP will also be decreased
