概要	The New York Heart Association (NYHA) Functional Classification is a four-category ordinal system for grading heart failure severity based on the level of physical activity that precipitates dyspnea or other HF symptoms. Established by the NYHA in 1928 and refined in 1994, the NYHA classification is the oldest and most widely used functional status metric in cardiology, providing a simple, clinically intuitive framework for describing HF symptom burden, guiding treatment intensity, and predicting prognosis.	The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item, multidimensional self-report measure that evaluates heart failure-related symptoms, functional limitations, and quality of life in patients with cardiomyopathy and heart failure of all severities. Developed by Spertus and colleagues in 2000, the KCCQ provides six disease-specific domains and a clinically summary score, making it ideal for comprehensive, domain-focused assessment in both clinical practice and research.
