Tratamento da Insuficiência Cardíaca com Fração de Ejeção Reduzida
A insuficiência cardíaca com fração de ejeção reduzida (ICFEr) é tratada com uma abordagem farmacológica estruturada e baseada em evidências, com o objetivo de reduzir a morbidade, as hospitalizações e a mortalidade cardiovascular.
Abordagem Terapêutica
As diretrizes atuais recomendam iniciar a terapia médica orientada por diretrizes em múltiplas classes de medicamentos simultaneamente em doses baixas — a inibição do sistema renina-angiotensina é um componente fundamental — com titulação até as doses-alvo conforme tolerado. Os critérios completos de seleção de classes, o algoritmo de decisão e as metas de titulação estão detalhados no protocolo completo.
Meta Clínica
Eliminação das evidências clínicas de retenção de líquidos e manutenção da euvolemia.

- Inhibition of the renin-angiotensin system is recommended to reduce morbidity and mortality for patients with HFrEF, and ARNi, ACEi, or ARB are recommended as first-line therapy.
- In patients with HFrEF and NYHA class II to III symptoms, the use of ARNi is recommended to reduce morbidity and mortality.
- In patients with previous or current symptoms of chronic HFrEF, the use of ACEi is beneficial to reduce morbidity and mortality when the use of ARNi is not feasible.
- In patients with previous or current symptoms of chronic HFrEF who are intolerant to ACEi because of cough or angioedema and when the use of ARNi is not feasible, the use of ARB is recommended to reduce morbidity and mortality.
- In patients with HFrEF, with current or previous symptoms, use of 1 of the 3 beta blockers proven to reduce mortality (eg, bisoprolol, carvedilol, sustained-release metoprolol succinate) is recommended to reduce mortality and hospitalizations.
- In patients with HFrEF and NYHA class II to IV symptoms, an MRA (spironolactone or eplerenone) is recommended to reduce morbidity and mortality, if eGFR is >30 mL/min/1.73 m² and serum potassium is <5.0 mEq/L.
- In patients with symptomatic chronic HFrEF, SGLT2i are recommended to reduce hospitalization for HF and cardiovascular mortality, irrespective of the presence of type 2 diabetes.
- In patients with HF who have fluid retention, diuretics are recommended to relieve congestion, improve symptoms, and prevent worsening HF.
- The treatment goal of diuretic use is to eliminate clinical evidence of fluid retention, using the lowest dose possible to maintain euvolemia.
