    BackgroundThe usefulness of physical examination findings for pulmonary hypertension (PH) is not well established. The purpose of this study was to evaluate prospectively the diagnostic performance of the physical examination for detecting PH.MethodsConsecutive patients undergoing right-sided heart catheterization (n = 116) were examined by an attending physician, medical resident, and medical student in a blinded fashion. Sensitivity, specificity, and positive and negative likelihood ratios (LRs) were calculated for each physical finding. Jugular venous pulsation (JVP) height was compared with right atrial pressure (RAP) by using linear regression. The association between physical findings and PH was assessed using univariate and multivariate logistic regression.ResultsThe prevalence of PH was 87%. Only a JVP > 3 cm (positive LR, 2.5; 95% CI, 1.2-5.4) and pulmonic regurgitation murmur (specificity, 100%; 95% CI, 79%-100%) helped rule in PH. The absence of JVP > 3 cm (negative LR, 0.4; 95% CI, 0.3-0.6) and absence of loud pulmonic component of the second heart sound (negative LR, 0.5; 95% CI, 0.3-0.9) had modest usefulness in excluding PH. JVP correlated with RAP (r = 0.59; P < .001) but tended to lead to underestimation of RAP (mean bias, -3.4 cm H2O; 95% limits of agreement, -14.0 to 7.2). The presence of JVP > 3 cm and a parasternal heave discriminated PH (area under the curve [AUC] = 0.75). The combination of JVP > 3 cm, heave, and peripheral edema discriminated severe PH (mean pulmonary arterial pressure ≥ 45 mm Hg; AUC = 0.82).ConclusionsIndividual physical examination findings have inadequate diagnostic usefulness for PH. No combination of findings can be used to exclude PH, but the presence of high JVP, peripheral edema, and parasternal heave suggests severe PH.Copyright © 2019 American College of Chest Physicians.
