Residual congestion and clinical intuition in decompensated heart failure

Congestive symptoms are the key to recognising decompensated heart failure, whose treatment is based on reducing the congestion until a clinical situation has been reached that allows the patient to be discharged to continue outpatient treatment. The important aspect is not the degree of congestion at admission but rather the congestion that persists after energetic diuretic therapy. The persistence of congestive signs following an apparently correct and effective therapy has been called residual congestion and is associated with a poor prognosis. The tools for determining this condition are still rudimentary. Methods therefore need to be developed that enable a more accurate assessment.
