Incidence of Pulmonary Hypertension in the Echocardiography Referral Population.

Rationale: Incidence rates for pulmonary hypertension using diagnostic data in patients with cardiopulmonary disease are not known.

Objectives: To determine incidence rates of, risk factors for, and mortality hazard associated with pulmonary hypertension among patients referred for transthoracic echocardiography Methods: Retrospective cohort study using data from the Veterans Health Administration (1999-2020) and Vanderbilt University Medical Center (1994-2020). Pulmonary hypertension was defined as pulmonary artery systolic pressure >35mmHg with prevalent cases excluded.
