[Risk stratification in pulmonary arterial hypertension - implementation of an internet-based risk calculator to guide treatment].

The 2022 ESC/ERS pulmonary hypertension guidelines recommend multiparametric risk stratification at diagnosis and follow-up to guide treatment in pulmonary arterial hypertension (PAH). The goal is to maintain or achieve a low-risk status, corresponding to a 1-year mortality < 5%. Risk assessment is, however, underutilized in clinical practice, and applied only by 60% of clinicians. To overcome the barrier of underutilization and facilitate risk assessment, we have established a comprehensive internet-based risk stratification calculator (https://www.svefph.se/risk-stratification).
