The study of risk in pulmonary arterial hypertension

A growing body of published evidence exists on the risk factors for disease progression in pulmonary arterial hypertension (PAH). The Scientific Steering Committee for the Study of Risk in PAH was established to bring together leading clinical and statistical experts in PAH and risk modelling, for the purpose of advancing the understanding of the risk of development and progression of PAH. Herein, we discuss the impact of this information on three key areas: 1) clinical decision-making; 2) policy and reimbursement; and 3) future trials and research.
