WHO's in Second to Fifth? Distinguishing PAH from Other Types of PH - Updated 11/4/2024
AMA/ANCC/ACPE - Lecture Library Set
PH is currently divided into World Health Organization (WHO) groups based on the perceived etiology of the vascular insult: PAH (Group 1), PH due to left heart disease (Group 2), PH due to lung disease and/or hypoxia (Group 3), PH due to pulmonary artery obstructions (Group 4), and PH due to unclear and/or multifactorial mechanisms (Group 5). Accordingly, therapeutic interventions to address PH differ significantly between groups. However, this classification is less than perfect as there is not only considerable heterogeneity within each group but also overlap between groups. Emerging evidence on phenotyping PH may assist to address these limitations. This slide set presents the latest research in diagnosing and managing Group 2-5 in patients, including a discussion of the distinctions in specific groups – CTEPH, PH-ILD, PH-COPD.

Updated information is noted on the slide in the upper right hand corner. Please note that participants who have previously claimed credit for this activity should not claim duplicate credit based on the updates.
Review this activity and claim AMA, ANCC, or ACPE credit/contact hours after completion of a brief pretest and post-test/evaluation.
