A Simple Echocardiographic Prediction Rule for Hemodynamics in Pulmonary Hypertension

.
.
.
The derived prediction rule ranged from -2 to +2 with higher scores suggesting higher probability of PHPVD: +1 point for left atrial AP dimension<3 -1="-1" .2cm=".2cm" a="a" acceleration="acceleration" e:e="e:e" for="for" lateral="lateral" mid-systolic="mid-systolic" mitral="mitral" msec="msec" notch="notch" of="of" or="or" presence="presence" time="time">10; -1 for left atrial AP dimension>4.2cm. PVR increased stepwise with score (for -2, 0 and +2, μPVR were 2.5, 4.5, and 8.1WU) while the inverse was true for PAWP (corresponding μPAWP were 21.5, 16.5 and 10.4mmHg). Among subjects with complete data, the score had an AUC of 0.921 for PHPVD. A score ≥0 had 100% sensitivity and 69.3% positive predictive value for PHPVD, with 62.3% specificity. No patients with a negative score had PHPVD. Patients with a negative score and acceleration time >100msec had normal PVR (μPVR=1.8WU, range=0.7-3.2WU).
