What is heart failure?
When the heart is unable to pump enough blood to meet the metabolic demands of the body
During heart failure, the heart can only pump enough blood with an elvated ____________.
Left Ventericular End Diastolic Pressure (LVEDP)
During heart failure, what is retained due to an increased release of Aldosterone from the Adreanal cortex?
NaCl and H2O
In heart failure, stimulation of the renin Angiotensin system will result in a decrease of _______ combined with _________ overload.
What causes pulmonary edema?
Decrease in Left Atrium Pressure (PCWP)
What is the most dramatic symptom of left heart failure?
What PCWP is seen with cardiogenic pulmonary edema?
PWCP >25-30 mmHg
