What is heart failure? - (ANSWER)condition when the heart becomes damaged or weakened by disease.
The myocardium cannot pump effectively to meet metabolic needs
Left ventricle (first, usually) isn't strong enough to accommodate the flow of blood back from the lungs
to the heart
Heart may not be able to relax properly to accommodate the flow of blood back from the lungs to the
heart. Causes fluid to back up in lungs and other parts of the body
What does ventricular function depend on? - (ANSWER)Preload, afterload, contractility, heart rate.
Two types of HF - (ANSWER)acute and chronic
Two types of systolic dysfunction - (ANSWER)left and right
What happens in systolic dysfunction? - (ANSWER)enlarged ventricles fill with blood and end up
pumping less than 40 to 50 (compared to 60) percent
What happens in diastolic dysfunction? - (ANSWER)Stiff ventricles fill with less blood than usual. Those
ventricles pump out about 60 percent, but the amount may be lower than normal.
What happens in LEFT systolic dysfunction? Volume, contractility, ventricle status, pumping force... -
(ANSWER)Volume overload and decreased contractility. Left ventricle can no longer pump normally.
Heart can't pump with enough force for proper circulation.

What are causes of LEFT SYSTOLIC dysfunction? Diseases, structural changes, effects on the muscle of
the heart and the O2 of the body - (ANSWER)CAD and hypertension.
Structural changes lead to deteriorated cardiac function.
Symptoms of low cardiac output and congestion.
Effects the myocardium - volume overload or cardiac injury.
Heart is unable to meet the body's metabolic requirements.
Where does blood pool in left sided heart failure? - (ANSWER)The ventricle, atrium and ultimately the
PULMONARY veins.
What happens with pulmonary congestion? - (ANSWER)This occurs when pulmonary circulation
becomes engorged - pressure in capillaries rises and pushes sodium and water into the interstitial
spaces. EDEMA.
What are symptoms of pulmonary congestion, edema etc. - (ANSWER)Decreased CO - congestion.
Poor gas exchange - edema.
Also: cyanosis, hypoxia, cough, frothy sputum, orthopnea, nocturnal dyspnea.
What happens with right sided heart failure? - (ANSWER)Congestion of the peripheral tissue.
What defect occurs in right sided HF? - (ANSWER)The right ventricle is not pumping adequately.
