Jugular Venous Pressure and Kussmaul's Sign as Predictors of Outcome in Heart Failure.

Simplifying the estimation of internal jugular venous pressure (JVP) as visible or not visible above the right clavicle in the sitting position has attracted attention for risk assessment in patients with heart failure (HF). It remains unclear whether this simple assessment, combined with its inspiration response known as Kussmaul's sign, is useful in patients with HF who vary in features such as HF with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF).This study consisted of 246 patients who were admitted for the management of HF.
