Q

Pathophysiology of Heart Failure

A
  • Overgrowth of heart
  • Increased Cardiac Output, from Adrenergic Activation : Contractility, and Heart Rate

Q

What is HFrEF

What are the problems with this?

A

Heart Failure Reduced Ejection Fraction
Systolic Heart Failure
Reduced Ejection Fraction (Ejects less than 40% normal volume)
-LV cavity is dilated, wall is lengthened, thin
-Impaired contractility
-Reduced tissue perfusion

Q

What is HFpEF

What are the problems with this

A

Heart Failure Preserved Ejection Fraction
Diastolic Heart Failure
Ventricle does not fill with blood well in the relaxation phase.
-LV is abnormally stiff, thick
-Impaired relaxation during diastole
-Unable to increase output in response to demands
-More common in women

Q

ACCF/AHA Stages/classes of HF

List em 4

A

A- At high risk but without structural heart disease or symptoms of HF
B- Structural heart disease but without signs or symptoms of HF
C-Structural heart disease with prior or current symptoms of HF
D- Refractory HF requiring

22
Q

NYHA Functional Classification

List em 4

A

I – No limitation of physical activity. Ordinary physical activity does not cause symptoms HF
II – Slight limitation of physical activity. Comfortable at rest, but ordinary physical activity results in symptoms of HF
III – Marked limitation of physical of physical. Comfortable at rest, but less than ordinary activity causes symptoms of HF
IV – Unable to carry on any physical activity without symptoms of HF, or symptoms of HF at rest.
