Evaluation of the European Society of Cardiology/European Respiratory Society derived three-and four-strata risk stratification models in pulmonary arterial hypertension : Introducing an internet-based risk stratification calculator

We therefore evaluated the various European Society of Cardiology (ESC)-/European Respiratory Society (ERS)-based three-and four-strata
