The Eurasian Guidelines for the Diagnosis and Treatment of Pulmonary Hypertension (2023) were developed by a working group of experts from various countries, including Russia, Kyrgyzstan, Azerbaijan, Belarus, Kazakhstan, and others. The guidelines aim to provide updated recommendations for the diagnosis and treatment of pulmonary hypertension (PH), including both pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). The working group members contributed equally to the document and confirmed the absence of conflicts of interest. The guidelines emphasize the importance of early diagnosis, accurate classification, and appropriate treatment strategies based on the underlying causes of PH. They also highlight the need for individualized care, considering the patient's specific condition and consulting with the patient. The guidelines include detailed sections on the etiology, pathogenesis, epidemiology, diagnosis, and treatment of PH, as well as specific recommendations for different types of PH, such as those associated with heart defects, connective tissue diseases, and other conditions. The guidelines also address the importance of monitoring and managing PH in various clinical settings, including surgical and endovascular treatments. The recommendations are based on a comprehensive review of scientific and medical evidence, and they aim to improve the management of PH and improve patient outcomes. The guidelines are intended for a wide range of healthcare professionals, including general practitioners, cardiologists, pulmonologists, surgeons, and others. The guidelines emphasize the importance of a multidisciplinary approach to the diagnosis and treatment of PH, and they provide detailed recommendations for the use of specific medications and therapies. The guidelines also include information on the functional classification of PH and the importance of monitoring patients for changes in their condition. The guidelines are designed to be a valuable resource for healthcare professionals involved in the care of patients with PH.The Eurasian Guidelines for the Diagnosis and Treatment of Pulmonary Hypertension (2023) were developed by a working group of experts from various countries, including Russia, Kyrgyzstan, Azerbaijan, Belarus, Kazakhstan, and others.
