Clinical guidelines are a set of recommendations developed by leading scientific and medical councils to support the best practice management of a particular disease. These are based on careful consideration of all the available evidence at the time they are written. Your doctor is likely to take these into account when planning the best management program to treat your PAH.
The guidelines that your doctor may follow will depend on the country that you live in. For example, the European Society of Cardiology (ESC) and European Respiratory Society (ERS) Guidelines for the diagnosis and treatment of Pulmonary Hypertension provide the main recommendations used for PAH care across Europe, while in the US, the American College of Chest Physicians (CHEST) has published guidelines for the management and treatment of PAH in adults. There may also be national guidelines on the management of PAH in your local country.
When planning your treatment, your PAH doctor will also consider which treatments are available in the country that you live in, as not all treatments are licensed in every country.
