Refined risk stratification in pulmonary arterial hypertension and timing of lung transplantation

In patients with pulmonary arterial hypertension (PAH) presenting with progressive disease despite optimised medical therapy, lung transplantation remains an important treatment option [1–3]. Current guidelines recommend assessing the individual mortality risk regularly using a three-stratum model to determine whether patients are at low, intermediate or high risk of death [1, 2]. The four-stratum risk assessment tool helps determining the right time for lung transplant listing in patients with pulmonary arterial hypertension https://bit.ly/3GrLSId
