About the Seattle Angina Questionnaire

The SAQ is a disease-specific, patient-reported outcome measure for patients with coronary artery disease. The original SAQ assesses physical limitation, angina stability, angina frequency, treatment satisfaction, and disease-related quality of life.

Each domain is scored from 0 to 100, with higher scores generally indicating fewer limitations, fewer symptoms, or better status in that domain. Domain scores are intended to retain their separate meanings.

Scoring and interpretation

Enter domain scores derived using the scoring algorithm for the exact SAQ version administered.
The SAQ Summary Score is calculated from Physical Limitation, Angina Frequency, and Quality of Life only; Angina Stability and Treatment Satisfaction are excluded from the summary score.
Clinical interpretation should consider the individual domains, patient context, and change over time.

Important version note

The original SAQ and the abbreviated SAQ-7 do not have identical domain structures. This calculator accepts five already-calculated domain scores and does not calculate item-level domain scores from questionnaire responses.
