Primary Pulmonary Hypertension
Abstract
Primary pulmonary hypertension is a condition characterized by sustained elevations of pulmonary-artery pressure without a demonstrable cause. The diagnostic criteria used in the National Institutes of Health (NIH) registry1 include a mean pulmonary-artery pressure of more than 25 mm Hg at rest, or more than 30 mm Hg with exercise, and the exclusion of left-sided cardiac valvular disease, myocardial disease, congenital heart disease, and any clinically important respiratory, connective-tissue, or chronic thromboembolic diseases. Pulmonary vascular disease with clinical and pathological features similar to those of primary pulmonary hypertension can occur in patients with portal hypertension,2 infection with the human immunodeficiency . . .

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
