298. Guidelines: 2022 AHA/ACC/HFSA Guide...

Ms. M is a 36-year-old G1P1 woman 6 months postpartum who was diagnosed with peripartum cardiomyopathy at the end of her pregnancy. She is presenting for a follow up visit today and notes that while her leg edema has resolved, she continues to have dyspnea when carrying her child up the stairs. She also describes significant difficulty sleeping, though denies orthopnea, and notes she is not participating in hobbies she had previously enjoyed. She is currently prescribed a regimen of sacubitril-valsartan, metoprolol succinate, spironolactone, and empagliflozin.  What are the next best steps?

A

Screen for depression

B

Counsel her to follow a strict low sodium diet with goal of < 1.5g Na daily

C

Recommend exercise therapy and refer to cardiac rehabilitation

D

A & C

Explanation

The correct answer is D – both A (screening for depression) and C (referring to cardiac rehabilitation) are appropriate at this time.

Choice A is correct. Depression is a risk factor for poor self-care, rehospitalization, and all-cause mortality among patients with HF. Interventions that focus on improving HF self-care have been reported

to be effective among patients with moderate/severe depression with reductions in hospitalization and mortality risk. Social isolation, frailty, and marginal health literacy have similarly been associated with poor HF self-care and worse outcomes in patients with HF. Therefore, in adults with HF, screening for depression, social isolation, frailty, and low health

literacy as risk factors for poor self-care is reasonable to improve management (Class 2a, LOE B-NR). 

Choice C is correct. In patients with HF, cardiac rehabilitation has a Class 2a recommendation (LOE B-NR) to improve functional capacity, exercise tolerance, and health-related QOL; exercise training (or regular physical activity) for those able to participate has a Class 1 recommendation (LOE A) to improve functional status, exercise performance, and QOL.

Choice B is incorrect. For patients with stage C HF, avoiding excessive sodium intake is reasonable to reduce congestive symptoms (Class 2a, LOE C-LD). However, strict sodium restriction does not have strong supportive data and is not recommended. There are ongoing studies to better understand the impact of sodium restriction on clinical outcomes and quality of life. The AHA currently recommends a reduction of sodium intake to <2300 mg/d for general cardiovascular health promotion; however, there are no trials to support this level of restriction in patients with HF.

Main Takeaway

Depression is a risk factor for poor HF self-care and worse outcomes in patients with heart failure and so it is reasonable to screen for depression in these patients. Exercise therapy and cardiac rehabilitation have been shown to improve outcomes in HF patients. While avoiding excess sodium intake is reasonable in HF patients to reduce congestive symptoms, there is no specific strict sodium level recommended.
