摘要	The Seattle Angina Questionnaire (SAQ) is a 19-item self-report measure that evaluates the frequency and severity of angina symptoms, functional limitations, and disease-specific quality of life in patients with coronary artery disease. Developed by Spertus and colleagues in 1995, the SAQ has become the gold-standard symptom-specific QoL instrument in cardiology and is recommended by major guidelines for assessing angina burden and treatment response.	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.
