Q

when should ISDN/hydralazine be recommended?

Study These Flashcards
A

stage C in black pts to improve symptoms and reduce M/M
pts with symptoms who can receive ARNi, ACEi, or ARB due to drug intolerance or renal insufficiency might be considered

21
Q

what is an example of a drug intolerance that might switch someone from an ARNI, ACEi, or ARB to ISDN/Hydralazine?

Study These Flashcards
A

persistent hyperkalemia

22
Q

when is ivabradine indicated?

Study These Flashcards
A

reduce the risk of hospitalization (worsening HF) in HFrEF in normal sinus rhythmn in max tolerated BB or with CI

23
Q

what is the dosing of ivabradine?

Study These Flashcards
A

initial: 2.5-5mg BID
max: 7.5 mg BID
adj q2 weeks based on HR

24
Q

if HR is over 60, what should ivabradine dose be?

Study These Flashcards
A

increase dose by 2.5 mg up to max dose

25
if HR is between 50-60, what should ivabradine dose be?
maintain current dose
26
if HR is under 50 or S/S bradycardia, what should ivabradine dose be?
decrease dose by 2.5 mg if current dose is 2.5mg BID, d/c
27
what are the AE of ivabradine?
fetal toxicity atrial fibrillation bradycardia and conduction disturbances
28
how does ivabradine being a CYP3A substrate affect it?
fairly substantial drug-drug interactions CI with KTZ avoid diltiazem, verapamil, GFJ
29
what drugs are cardiac glucosides?
digoxin digitalis glycosides
30
what is the major benefits of digoxin?
increase parasympathetic activity vagolytic effects at the AV and SA nodes to reduce HR at rest and slow AVN conduction (afib tx) re-sensitization of baroreceptors
31
how do cardiac glycosides affect the Na/K ATPase pump?
inhibits it to alter excitation-contraction coupling increases intracellular Ca2+ enhance force of contraction relatively mild positive inotrope
32
when is digoxin considered in HF?
pts who have symptomatic HFrEF despite optimized GDMT or who can't tolerate GDMT to decrease hospitalization for HF controversial
33
how is digoxin dosed?
empirically based on goal serum digoxin concentration (SDC) 0.125-0.25 mg daily with most being on lower dose
34
what is goal SDC?
between 0.5-0.9 ng/mL
35
when should lower doses of digoxin be considered?
pts over 70 yrs, impaired renal function, low weight
36
what drugs have interaction with digoxin?
amiodarone quinidine verapamil itra/KTZ increases digoxin concentration x2
37
what are non cardiac AE of digoxin?
anorexia, NV, abdominal pain visual disturbances fatigue, weakness, dizziness, HA, neuralgias, confusion, delirium, psychosis
38
what are the ventricular AE of digoxin?
PVCs bigeminy trigeminy VT VF
39
what are cardiac AE of digoxin?
ventricular 1,2,3 degree AV block AV junctional escape rhythms, junctional tachycardia atrial arrhythmias with slowed AV conduction or AV block sinus bradycardia
40
what type of drug is vericiguat?
soluble guanylate cyclase stimulator
41
what are AE and CI of vericiguat?
CI in pregnancy AE -- hypotension and anemia
42
when should vericiguat be considered?
in selected high-risk pts with recent worsening with symptomatic HFrEF despite optimized GDMt used to decrease hospitalization for HF and CV death
43
what is the role of PUFA in HF?
omega-3 polyunsaturated FA may reduce risk in HF (II-IV) pts reasonable as adjunctive therapy
44
what is the role of antiplatelets in HF tx?
long term therapy with aspirin is recommended in pts with HF and IHD/CAD/ASCVD only not recommended for routine use
45
what is the role of anti-coags in HF?
not recommended unless pt with other indication (hx of systemic or pulmonary embolism), in HF with Afib with one addition R/F
46
what is the role of CCBs in HF?
do not use diltiazem, verapamil, and nifedipine felodipine and amlodipine may be useful in managing angina/HTN if not effectively managed by other HF therapies
47
when would an ICD be implanted?
LVEF under 35% with 40 days post MI, NYHA II-III LVEF under 30% at least 40 days post MI, NYHA I
48
when is cardiac resynchronization therapy recommended in HF?
NYHA II-IV pts on optimal medical therapy with QRS duration over 150 milliseconds and LVEF under 35%
49
what are other therapies that show no benefit or conflicting benefit?
coenzyme Q10 nutritional therapies hormonal therapies
