Threshold Of Pulmonary Hypertension Associated With Increased Mortality
This screening study of more that 150,000 adults found a prevalence of pulmonary hypertension of greater than 18% ranging from mild to severe. In addition, they were able to show increasing mortality with the severity of pulmonary hypertension, beginning at the very lowest levels.

Mild Pulmonary Hypertension and Premature Mortality Among 154 956 Men and Women Undergoing Routine Echocardiography
This large study of over 150,000 adults from the NEDA goes into deeper analysis to show how mild levels of elevation in pulmonary arterial pressure is associated with increased mortality in the general population. They conclude that notional screening strategies should be considered in as part of clinical surveillance programs.

Increasing Incidence and Prevalence of World Health Organization Groups 1 to 4 Pulmonary Hypertension: A Population-based Cohort Study in Ontario, Canada
This Canadian study includes a cohort of over 50,000 patients with pulmonary hypertension over a 10-year period. They confirm that the incidence and prevalence of pulmonary hypertension is increasing, with Group 2 and group 3 associated with the highest mortality.

Association Of Borderline Pulmonary Hypertension With Mortality And Hospitalization In A Large Patient Cohort: Insights From The Veterans Affairs Clinical Assessment, Reporting, And Tracking Program
This is a retrospective study of over 20,000 patients with pulmonary hypertension confirmed by cardiac catheterization, from any cause who were followed for clinical outcomes. Like other studies it confirmed the increasing mortality beginning at the mildest levels of increased pulmonary artery pressure. The case can be made for screening programs to detect early disease to initiate treatments.
