Heart Failure

Heart failure requires phenotype-specific confirmation, rapid identification of reversible precipitants, early disease-modifying therapy for reduced ejection fraction, and surveillance for congestion, arrhythmia, renal dysfunction, and progression to advanced therapies. Management must align treatment intensity with hemodynamics, comorbidity, and patient goals.

Clinical question: How should clinicians confirm, phenotype, treat, and longitudinally monitor heart failure while identifying candidates for advanced therapies?

Diagnosis

Confirm the syndrome and define the phenotype

Use symptoms, examination, biomarkers, imaging, and etiologic assessment rather than ejection fraction alone.

Heart failure is a clinical syndrome caused by structural or functional impairment of ventricular filling or ejection. Dyspnea, fatigue, congestion, and edema are common but nonspecific; no single diagnostic test is sufficient. A prior low EF without clinical evidence of heart failure should not be equated with heart failure. AHA Journals2021 ACC/AHA Key Data Elements and Definitions for Heart Failure: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Data Standards (Writing Committee to Develop Clinical Data Standards for Heart Failure)PubMedDiagnosing heart failure - Chronic Heart Failure in Adults - NCBI Bookshelf

Initial assessment should establish acuity, congestion versus hypoperfusion, blood pressure, rhythm, ischemic symptoms, valve disease, renal and hepatic dysfunction, and competing cardiopulmonary diagnoses. Obtain ECG, chest radiography when clinically useful, CBC, renal function and electrolytes, liver tests, thyroid testing, glycemic assessment, and transthoracic echocardiography to evaluate ventricular systolic and diastolic function, valves, chamber size, and shunts. PubMedDiagnosing heart failure - Chronic Heart Failure in Adults - NCBI Bookshelf

Classify by LVEF: HFrEF at 40% or less, HFmrEF above 40% to below 50%, HFpEF at 50% or greater, and HF with recovered EF when a previously reduced EF improves to at least 50%. These categories guide evidence application but do not define etiology or filling pressures.

Sacubitril/valsartan is FDA-indicated to reduce cardiovascular death and heart failure hospitalization in adults with chronic heart failure, with benefit most clearly evident when LVEF is below normal. The usual adult starting dose is 49/51 mg orally twice daily, titrated every 2 to 4 weeks as tolerated to 97/103 mg twice daily; begin at half the usual starting dose for severe renal impairment, moderate hepatic impairment, or no/low prior ACE inhibitor or ARB exposure. Do not coadminister with an ACE inhibitor; allow a 36-hour washout when switching from an ACE inhibitor. accessdata fdaENTRESTO® (sacubitril and valsartan) tablets, for oral use ...

Metoprolol succinate is FDA-indicated for stable symptomatic NYHA II or III heart failure. Start 25 mg once daily for 2 weeks in NYHA II or 12.5 mg once daily in more severe heart failure, then double every 2 weeks to the highest tolerated dose or 200 mg daily. Stabilize other heart failure therapy first; with transient worsening heart failure, intensify diuresis and restore clinical stability before further titration. Avoid abrupt discontinuation. accessdata fdaMetoprolol succinate - accessdata.fda.gov

Acute congestion and decompensation

Acute pulmonary edema or pulmonary congestion requires rapid assessment of oxygenation, perfusion, blood pressure, ischemia, arrhythmia, renal function, and precipitating causes. Invasive hemodynamics may be useful when noninvasive testing does not resolve diagnostic uncertainty or when refractory symptoms require precise characterization of filling pressures, cardiac output, and pulmonary pressures.

Etiology matters

Modify treatment when cardiomyopathy physiology changes the risk

Heart failure management changes substantially when obstruction, infiltrative disease, or systolic decline is present.

In obstructive hypertrophic cardiomyopathy, dynamic outflow obstruction is sensitive to preload, afterload, and contractility. A peak LVOT gradient of at least 30 mm Hg defines obstruction; resting or provoked gradients of at least 50 mm Hg are generally considered capable of causing symptoms and are the threshold for advanced pharmacologic or invasive strategies when symptoms are refractory. AHA Journals2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for ...

For symptomatic obstructive hypertrophic cardiomyopathy, nonvasodilating beta blockers are first-line. Verapamil or diltiazem are alternatives. Persistent symptoms despite first-line therapy may prompt consideration of a cardiac myosin inhibitor in adults, disopyramide with an AV nodal blocking agent, or septal reduction therapy at an experienced HCM center. AHA Journals2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for ...

Avoid or reconsider pure vasodilators, high-dose diuretics, and positive inotropes in symptomatic obstructive hypertrophic cardiomyopathy because reduced preload or afterload and increased contractility can worsen obstruction. Low-dose diuretics may be used cautiously for persistent congestive symptoms. AHA Journals2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for ...

Longitudinal care

Monitor trajectory and refer before advanced disease becomes irreversible

Serial assessment should detect congestion, arrhythmia, progressive dysfunction, and advanced-therapy eligibility.

Follow-up should include symptoms, NYHA class, blood pressure, heart rate and rhythm, weight and volume status, renal function, electrolytes, medication tolerance, and adherence. Heart failure data standards also identify functional assessment, patient-reported outcomes, cardiopulmonary exercise testing, rhythm monitoring, and invasive hemodynamics as appropriate tools in selected patients. AHA Journals2021 ACC/AHA Key Data Elements and Definitions for Heart Failure: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Data Standards (Writing Committee to Develop Clinical Data Standards for Heart Failure)

In hypertrophic cardiomyopathy, serial transthoracic echocardiography every 1 to 2 years in asymptomatic patients can assess changes in systolic and diastolic function, wall thickness, chamber size, LVOT obstruction, and valvular disease. Ambulatory ECG monitoring every 1 to 2 years is reasonable for arrhythmia surveillance in patients without ICDs. AHA Journals2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for ...

Advanced heart failure develops in an estimated 3% to 8% of patients with hypertrophic cardiomyopathy. Refer for transplant evaluation when severe symptoms or recurrent ventricular arrhythmias persist despite optimized medical therapy and septal reduction is not an option; preserved EF does not exclude advanced restrictive physiology or transplant candidacy.

Common questions

What establishes a diagnosis of heart failure?

Diagnosis requires compatible clinical symptoms or signs plus evidence of relevant structural or functional cardiac abnormality; a reduced LVEF alone is insufficient. AHA Journals2021 ACC/AHA Key Data Elements and Definitions for Heart Failure: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Data Standards (Writing Committee to Develop Clinical Data Standards for Heart Failure)PubMedDiagnosing heart failure - Chronic Heart Failure in Adults - NCBI Bookshelf

How should suspected heart failure be evaluated initially?

Use history, examination, ECG, laboratories for reversible contributors, natriuretic peptide testing when appropriate, and transthoracic echocardiography to define function, structure, valves, and shunts. PubMedDiagnosing heart failure - Chronic Heart Failure in Adults - NCBI Bookshelf

When should sacubitril/valsartan not be used?

Do not use with an ACE inhibitor or within 36 hours of ACE inhibitor exposure, in patients with prior ACE inhibitor- or ARB-related angioedema, or with aliskiren in diabetes. Monitor renal function and potassium. accessdata fdaENTRESTO® (sacubitril and valsartan) tablets, for oral use ...

When should patients with hypertrophic cardiomyopathy be referred to an expert center?

Refer for complex diagnostic or genetic issues, difficult ICD decisions, refractory obstruction, septal reduction therapy, complex arrhythmia management, or advanced heart failure and transplant assessment. AHA Journals2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for ...

Can advanced heart failure occur with preserved ejection fraction?

Yes. In hypertrophic cardiomyopathy, restrictive physiology can produce severe heart failure despite preserved EF; advanced therapy and transplant referral should be based on clinical trajectory, not EF alone. AHA Journals2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for ...
