When Chikungunya virus disease occurs in a patient with pre-existing heart failure, the fever itself becomes a haemodynamic stressor — and the risk of acute cardiac decompensation is substantially elevated. This scenario calls for a targeted management approach.
In patients with heart failure, fever may cause tachycardia and increased metabolic demands leading to decompensation of cardiac functions. Recognition of this high-risk overlap is the first step toward appropriate intervention.
The protocol addresses management of decompensated heart failure in this setting. Ventilatory support is among the interventions considered — the complete sequence of decisions, thresholds, and additional measures is detailed in the full regimen.
