renin release=vAngiotensin2=
peripheral vasodilation
renal vasodilation
suppression of aldosterone-mediated volume expansion
angiotensin converting enzyme inhibitors (ACE) effects
peripheral/renal vasodilation
suppression of aldosterone mediated volume expansion
blocking aldosterone receptors in kidney promotes ____ excretion=___blood volume
sodium/water excretion= decreased blood volume
(HTN) what medication should patients with renal disease take?
aa?
pregnant?
renal disease-take ace/arb (renal protective)
AA-diuretic (thiazide)/ ccb+bblocker (monotherapy less effective)
pregnant-methlydopa/labetolol
CHF drugs

Beta blockers used for CHF
carvedilol
bisoprolol
metoprolol
what symptomatic CHF drug is used if maxed out on Bblockers w HR >70
Ivabradine
What role does digoxin/inotropes have in CHF treatment?
K/dig compete

xxxxProlong life/ stop remodeling
Cardiac drug for black patients only
isosorbide/dinitrate
Stage A CHF tx
Stage B CHF tx
stage a- risk mgmt
stage B (remodeling w/o sx)- ACE/ARB
can add BB w vEF/MI hx
