19
Q

MOA spironlactone/eplirione?

A

compete w/aldosterone for intracellular mineralcortocoid receptor causing Na/H2O to excrete which decreases preload

20
Q

Aldosterone blockers in indicated for which stages of HF?

A

C and D HF

21
Q

ADE aldosterone blockers

A

hyperkalemia
gynecomastia
CI: hyperkalemia

22
Q

Are aldosterone blockers protein bound?Where are they excreted?

A

Yes, Highly

Kidneys

23
Q

Vasodilator drugs

A

hydralazine

isosorbide dinitrate

24
Q

hydralazine MOA

A

direct arterial vasodilator- coronary, cerebral and renal arteries
HA (hydralzaine arterial)

25
Q

Isosorbide dinitrate MOA

A

direct venodilator - convert into NO for vasodilation

26
Q

Vasodilators are indicated for what patients?

A

African American pts with stage C HF (along w/ ACE, BB etc)
used in B/C/D HF
Not CI to ACE I
Any race!

27
Q

ADE of vasodilators

A

Tolerance to nitrates
hypotension
CI: not really excreted

28
Q

Are vasodilators dosed multiple times a day?

A

Yes so they have bad compliance

29
Q

What are the Loop Diuretics?

A

Furosemide
butmetanide
torsemide

30
Q

Whats the MOA of Loops?

A

Exert action at loop of henle
increases Na + H2O excreted
reduces preload and edema

31
Q

What is the indication of Loops?

A

Initial: Sx HF (C or D)
goal: after diuresis + fluid reduction, get pt to lowest dose possible or consider d/c

32
Q

ADE Loops

A

electrolytes- hypokalemia, hypomagnesemia, hyperglycemia, hyperuricemia

33
Q

Do pts with renal failure need higher or lower doses of Loops?

A

Higher

34
Q

MOA Digoxin

A

increase inotropic activity and decrease chronotropic activity
increase intracellular Na + Ca which increases force of contraction

35
Q

Indication Digoxin

A

low dose for normal renal fxn
only in Sx HF stage C/D
elderly/renal insufficient- dose every other day!

36
Q

ADE digoxin

A

Toxicity- monitor it!
electrolytes- hypokalemia, hypomagnesemia
bradycardia
GI disturbance

37
Q

Why do the elderly/renal insufficient have a lower dose of digoxin?

A

a large VD

large in obese/small in elderly and primarily renally excreted

38
Q

Drugs to use for Morbidity?

A

morbiDDDD

digoxin and diuretics

39
Q

How does potassium effect digoxin?

A

hypoK increases effects

hyperK decreases effects

40
Q

What are the 4 compensatory mechanism of HF

A

RAAS
SNS
Ventricular Hypertrophy
Frank Starlings Law of the heart

41
Q

What blocks the RAAS

A

ACE-I ARBs Aldosterone blockers

42
Q

What blocks the SNS

A

BB

43
Q

What blocks ventricle hypertrophy

A

BB ACE-I ARBs Aldosterones

44
Q

What Blocks the Frank Starling Law

A

Hx of HF because there is a natural temporary fixing of first event HF (NO hx MI)

45
Q

What drugs are used to prevent mortality?

A

ACE I/ARBS
BBs
Aldosterone blockers
Vasodilators (in AAs)
