The NYHA classification, established in 1921, categorizes heart failure patients into four classes based on their symptoms and limitations during physical activity. Despite its simplicity and prognostic value, recent advancements in heart failure treatment have raised questions about the classification's effectiveness, particularly for patients with reduced ejection fraction. The document explores the limitations of the NYHA classification in clinical trials and suggests that patient-reported outcomes may provide a more accurate assessment of health status.
