Red Flags

  • Cardiogenic shock — hypotension, cool peripheries, oliguria, elevated lactate on top of decompensated heart failure — immediate ICU and inotropic/MCS support[1]
  • Acute pulmonary oedema with respiratory distress and SpO₂ <90% on supplemental oxygen — IV diuretic, NIV, urgent inpatient cardiology[1]
  • New-onset symptoms with NT-proBNP ≥ 2000 ng/L — refer for specialist assessment within 2 weeks; ≥ 400 within 6 weeks[1]
  • Decompensation in established HF with weight gain >2 kg in 3 days, worsening orthopnoea, or NYHA class deterioration[1]

First-line treatment

Interventions

  • Cardiac rehabilitation and lifestyle[1]
    Structured supervised exercise programme, sodium and fluid moderation, smoking cessation, alcohol limitation, vaccination (influenza, pneumococcal, COVID-19)
  • Rapid in-hospital optimisation[1]
    Initiate or up-titrate the four pillars of HF therapy during the index admission rather than after discharge — the 'STRONG-HF' protocol; reduces 6-month death and rehospitalisation

First-line drug therapy

DrugClassAdultPaediatricNotes
Ramipril or perindopril[1]ACE inhibitorRamipril 1.25–10 mg PO daily; perindopril 2–8 mg daily; titrate over 2–4 weeks—Pillar 1 of HFrEF foundation therapy. Switch to sacubitril/valsartan if intolerant or symptomatic on optimised dose
Sacubitril/valsartan (ARNI)[1]Angiotensin receptor-neprilysin inhibitor49/51 mg PO BD, titrate to 97/103 mg BD; allow 36-hour washout from prior ACE inhibitor—Class I for HFrEF in place of ACE-i. Cornerstone of foundation therapy
Bisoprolol[1]Beta-blocker (cardioselective)Start 1.25 mg PO once daily, titrate to 10 mg once daily over 4–8 weeks—Pillar 2 of HFrEF foundation therapy. Carvedilol or metoprolol succinate are interchangeable
Spironolactone[1]Mineralocorticoid receptor antagonist (MRA)12.5–25 mg PO once daily, up-titrate to 50 mg if tolerated and K+ <5.5—Pillar 3 of HFrEF foundation therapy. Eplerenone if gynaecomastia. Monitor K+ and creatinine
Dapagliflozin or empagliflozin[1]SGLT2 inhibitor10 mg PO once daily—Pillar 4 of foundation therapy. 2023 update extends Class I to HFmrEF AND HFpEF — full LVEF spectrum
Furosemide[1]Loop diuretic20–80 mg PO daily; titrate to symptom and weight control—For congestion. Does not improve mortality — use lowest effective dose
Ferric carboxymaltose or ferric derisomaltose[1]IV ironPer package weight-based regimen, single or split infusions—Symptomatic HFrEF or HFmrEF with iron deficiency (ferritin <100 µg/L OR ferritin 100–299 with transferrin saturation <20%); reduces HF hospitalisation

Safety-net

  1. Weigh yourself daily — gain of >2 kg in 3 days means more fluid is building up; contact your clinician same day[1]
  2. Worsening breathlessness, leg swelling, sleeping propped up on more pillows, or new dizziness — call your clinician same day; severe distress means emergency services[1]
  3. Continue all four heart-failure medications even when feeling well — stopping any one increases the risk of decompensation[1]

Referral criteria

  • Cardiogenic shock or acute pulmonary oedema with SpO₂ <90% on oxygenEmergency department for IV diuretic, NIV, and ICU consideration[1]
  • Suspected heart failure with NT-proBNP ≥2000 ng/LCardiology and specialist heart-failure team within 2 weeks[1]
  • Suspected heart failure with NT-proBNP 400–2000 ng/LCardiology and echocardiography within 6 weeks[1]
  • HFrEF symptomatic on optimised quadruple therapy with QRS ≥130 ms or LVEF ≤35%Cardiology for cardiac resynchronisation or ICD evaluation[1]

Clinical summary

Diagnosis and management of acute and chronic heart failure across HFrEF, HFmrEF, and HFpEF, with foundational quadruple therapy and SGLT2 inhibitors across the LVEF spectrum.
