Pathophysiology of heart failure Flashcards
What is cardiac output equation?
Stroke volume x heart rate
Wwhat affects stroke volume?
Preload (filling pressure)
Contractility
Afterload
Define heart failure
An inability of the heart to maintain an adequate perfusion of the tissues (cardiac output) at a normal filling pressure
It is syndrome of signs and symptoms that may be caused by a variety of pathological conditions
What happens to blood volume in Heart Failure
Increased
What happens to blood volume in Hypovolaemic Shock
Decreased
What happens to JVP in Heart Failure
Increased
What happens to JVP in Hypovolaemic Shock
Decreased
What happens to pulse rate in Heart Failure
Same
What happens to pulse rate in Hypovolaemic Shock
Increased
What happens to cardiac output in Heart Failure
Decreased
What happens to cardiac output in Hypovolaemic Shock
Decreased
What happens to Total peripheral resistance in Heart Failure
Increased
What happens to Total peripheral resistance in Hypovolaemic Shock
Increased very much
Is it chronic or acute Heart Failure
chronic both
Is it chronic or acute Hypovolaemic Shock
acute
