Q

What does the ANP or the BNP do?

A

Vasodilation
ANP/BNP do naturiesis- increase Na + excretion

Q

Define diastolic heart failure

A

impaired relaxation of the ventricles (ventricles become stiff) lots of high pressure, decrease compliance

Q

How does the LVEDP/compliance change in systolic heart failure?

A

increase, increase compliance.
cant pump out blood, therefore LVEDP increases and because of the volume overload the heart starts to expand and accomodate more blood therefore compliance increases

Q

In diastolic heart failure- how does contractility + compliance change?

A

increase contractility because increased pressures
decrease compliance (because of the way the sarcomeres are added)

Q

concentric hypertrophy is associated with which type of heart failure

diastolic heart failure

17
Q

High output failure causes

A

thiamine def
anemia
hyperthyroidism
AV fistula (dialysis arterial vein/Pagets disease)

18
Q

Loop diuretic and digoxin- does it improve survival?

A

no, only helps alleviate symptoms

19
Q

What is the function of aldosterone?

A

Increase Na absorption, Increase excretion of K+

PCWP is a surrogate marker

A

LAP (left atrial pressure)
