When acute rheumatic fever is complicated by carditis or progresses to heart failure, management extends beyond standard anti-inflammatory care. Cardiac involvement requires targeted intervention to reduce haemodynamic stress and limit the risk of lasting valvular injury.

Clinical Scenario

This protocol applies to acute rheumatic fever presenting with carditis or heart failure. In severe or acute carditis, dedicated heart failure management may be necessary. Severe carditis or pericarditis with effusion may also call for additional anti-inflammatory measures.

Treatment Approach — Partial Overview

The approach in this setting centres on reducing cardiac volume and pressure load. An aldosterone antagonist and an ACE inhibitor form a core part of the strategy, with vasodilatory therapy available as an additional option when initial diuretic response is limited. The complete agent selection, paediatric versus adult considerations, sequencing, and specific indications are detailed in the full structured protocol.

Treatment of heart failure may be required in severe, acute carditis.
Corticosteroids for severe carditis or pericarditis with effusion.
Spironolactone may be added for patients having limited or no response to loop diuretic, 12.5–25 mg spironolactone orally daily.
ACE inhibitor is recommended in patients with moderate or severe left ventricular systolic dysfunction, unless contraindicated.
Nitrate therapy may be added for patients having limited or no response to diuretic therapy, whose systolic blood pressure is greater than 90 mmHg. Intravenous or topical glyceryl trinitrate may be used.
