True or false: NSAIDs help relieve fluid overload and in turn, help relieve symptoms of heart failure

False. NSAIDs play a role in sodium and water retention, exacerbating heart failure symptoms

Examples of initial therapy

. Identify and treat etiology if possible
. Treat risk factors
. Remove exacerbating meds
. Low salt diet (<2-3 g/day)
. Monitor weight (>2lbs/day or >5lbs/week in fluid weight is concerning)
. Restrict fluid intake

Ischemic- damage due to blockage
Non ischemic- usually inherited cardiomyopathy. no blockage has lead to damage

What is heart failure?

Disorder in the ability of the heart to contract and/or relax, prohibiting the heart from ejecting enough blood

What is cardiomyopathy?

Disease that entails structural changes in the heart

What is the difference between heart failure and cardiomyopathy?

Cardiomyopathy- structural changes in the heart, no symptoms yet
Heart failure- symptoms of cardiomyopathy

What is systolic dysfunction?

Impairment in the ability of heart to contract

What is diastolic dysfunction?

Impairment in the ability of the heart to relax

What is considered mid range ejection fraction?

Between 40% - 50%

Patients with HTN are more likely to experience (systolic/diastolic) dysfunction

Diastolic

Ejection fraction that classifies HFrEF

40% and lower

Ejection fraction that classifies HFpEF

50% and greater

Systemic congestion, abdominal pain and jugular venous distention are signs and symptoms of (left/right) sided heart failure

Right

What are signs and symptoms of left sided heart failure?

. Pulmonary congestion (wet cough) . Pulmonary rales and edema . Dyspnea

When assessing inheritance of cardiomyopathy, how many generations of family history should be collected?

3 generations

What lab values and biomarkers should be assessed in HF patients?

. ECHO . BNP or NT-proBNP . Chest X-ray . Cath report . MRI

What is BNP and what does is indicate?

Brain natriuretic peptide. It is released when there is stretching in the ventricles, indicating cardiomyopathy

How is ejection fraction calculated?

Amount of blood pumped out of the ventricles (stroke volume) / Total amount of blood in relaxed ventricle (end-diastolic volume)

What are the 4 pillars of heart failure treatment?

. RAAS . BB . MRA . SGLT2i

When titrating up to a target dose, adjustments occurs at every ___ - ___ weeks depending on hemodynamic parameters, symptoms, and laboratory data

2-4 weeks

True or false: An important monitoring parameter for an HF patient using Entresto is BNP

False. Pro-BNP levels must be taken, BNP not a good indicator for ARNi class

Which beta blockers are approved for use in HF treatment?

Carvedilol, Bisoprolol and Metoprolol succinate

Important monitoring parameter of beta blockers in diabetic patients

Can mask hypoglycemia symptoms in DM patient except sweating

What is an uncommon, but possible side effect of MRAs?

Hirsutism

Cautions of SGLT2i medications

. Increased risk of mycotic genital infections . Necrotizing fasciitis of the perineum (Fournier's gangrene)

Which of the following thiazide diuretics is preferred in patients with heart failure? a. Metolazone b. Hydrochlorothiazide c. Chlrothalidone

a. Metolazone

BiDil generic name and MOA

Hydralazine/Isosorbide Dinitrate. Direct vasodilation of arterioles (hydralazine) and stimulation of intracellular cGMP (isosorbide dinitrate)

BiDil is contraindicated with concomitant use with which medication class?

PDE5 inhibitors. Sildenafil, tadalafil, vardenafil

When is ivabradine indicated in HF treatment?

For patients with resting Hr > or equal to 70, on maximally tolerated BB dose in NSR, class I/III
