Heart Failure Flashcards
Which beta-blockers decrease mortality in HFrEF?
Carvedilol, metoprolol succinate (XL), Bisoprolol
BB AEs
Bradycardia, bronchospasm (esp non-selective BB)
BB management in HF exacerbation
Do not initiate while in a heart failure exacerbation
Reduce dose if patient experiencing an exacerbation (try not to discontinue if possible)
Bisoprolol: Specificity, starting, and target dose
Specificity: B1 selective
Starting dose: 2.5 mg daily
Target dose: 10 mg daily
Metoprolol succinate: Specificity, starting, and target dose
Specificity: B1 selective
Starting dose: 12.5-25 mg daily
Target dose: 200 mg daily
Carvedilol: Specificity, starting, and target dose
Specificity: alpha 1, B1, B2
Starting dose: 3.125 mg - 6.25 mg twice daily
Target dose: 25 mg twice daily (if > 85 kg: 50 mg twice daily)
BB decrease mortality in HFrEF (T/F)
TRUE
Preferred agent in HFrEF: ACEI/ARB/ARNI?
ARNI
Sacubitril/valsartan brand name
Entresto
Sacubitril MOA
Blocks breakdown of B-type natriuretic peptide → vasodilation and natriuresis
ARNI washout
ACEI: 36 hours
ARB: NONE
ACEi/ARB/ARNI decrease mortality in HFrEF (T/F)
TRUE
MRA MOA
Competitive antagonists of the mineralocorticoid receptor → decreasing sodium reabsorption and increasing potassium reabsorption
What is the eGFR or SCr or K+ requirement for initiating an MRA?
GFR>30, SCr<2.5 (male), SCr<2 (females), K<5
MRA Monitoring (HF)
Electrolytes and renal function 2-3 days after initiation, then again 7 days after initiation/titration. Then check monthly for 3 months and every 3 months afterwards
Selective MRA
Eplerenone
Spironolactone AE
HyperK, gynecomastia, breast tenderness, impotence
Eplerenone: Starting and target dose
25mg daily, 50 mg daily
Spironolactone: Starting and target dose
12.5-25mg daily, 25-50 mg daily
MRAs decrease mortality in HFrEF (T/F)
TRUE
SGLT2 inhibitor MOA
Osmotic diuresis via glucose excretion, likely improvement in cardiac metabolism
SGLT2i AE
Dehydration, UTI, hypoglycemia (if they also have diabetes)
Dapagliflozin brand name
Farxiga
Dapagliflozin dose
10 mg
eGFR must be above ___ for dapagliflozin initiation
30 mL/min/1.73m2
Empagliflozin brand name
Jardiance
Empagliflozin dose
10 mg (only titrate up to 25 mg for glycemic control)
eGFR must be above ___ for empagliflozin initiation
20 mL/min/1.73 m2
Indication for hydralazine/isosorbide
NYHA III IV: persistently symptomatic Black patients on ARNI/BB/MRA/SGLT 2 inhibitor
