Background: Although the Seattle Angina Questionnaire (SAQ) has been widely used to assess disease-specific health status in patients with CAD, the original psychometric work was done in a VA cohort. As such, scarce data exist on the reliability and responsiveness of SAQ in women with CAD.
Methods: PRESS and PRISM were prospective registries of patients undergoing PCI that assessed health status serially using the SAQ. Reliability was assessed in PRESS, where SAQ scores were collected monthly for 6 months post PCI, by comparing SAQ scores and intraclass correlation at months 5 and 6among patients with no PCI or ACS between assessments (i.e., stable). Responsiveness was assessed in PRISM by comparing SAQ scores before and 1 month after PCI using standardized response means.
Results: Among 165 patients with stable CAD in PRESS (50 women), the reliability of the SAQ subscales and summary scores between 5 and 6 months after PCI was excellent (ICC ≥0.78) in both men and women. Among 1047 patients undergoing PCI in PRISM (277 women), all SAQ scales except treatment satisfaction were highly responsive after PCI in both men and women, with at least a 15-point difference in scores (Table).
Conclusion: The SAQ demonstrates similarly good reliability and responsiveness in both men and women with coronary artery disease. Concerns about the SAQ performance in women seem unwarranted.
