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. JVP was assessed before discharge and considered high if visible at rest. The inspiration response was also examined. The primary outcome was a composite of all-cause death and hospitalization for worsening HF.One year after discharge, primary outcome events occurred in 91 patients (37%). The incidence of primary outcome was higher in patients with a high JVP at rest (odds ratio, 5.06; 95% confidence interval, 2.31-11.1; P = 0.0001) or with inspiration (odds ratio, 5.93; 95% confidence interval, 2.14-16.4; P < 0.01) than in patients without high JVP conditions. These findings were similarly observed among patients with HFrEF and HFpEF (odds ratios, 3.53 and 6.76; 95% confidence intervals, 1.68-8.68 and 2.19-15.5; P = 0.01 and < 0.01, respectively) and in subgroup analysis stratified by baseline characteristics of the patients.A high JVP at rest and with inspiration as assessed by this simple, practical method may be useful for risk assessment in patients with HF, independent of baseline characteristics.
