Comparison of the Seattle Angina Questionnaire With Daily Angina Diary in the TERISA Clinical Trial
Key result
SAQ angina frequency scores strongly correlate with daily diary entries in patients with stable angina.
- Correlation -0.64
- 95% CI -0.68 to -0.60
- n=917
Why the study?
Does the Seattle Angina Questionnaire (SAQ) angina frequency domain correlate with daily diary records of angina frequency and sublingual nitroglycerin use in patients with stable angina?

Main Result

The SAQ angina frequency domain is a valid measure of angina frequency and sublingual nitroglycerin use, correlating strongly with daily diary entries in patients with stable angina.
Cite This Study
Arnold et al. (2014) conducted an observational in Type 2 diabetes mellitus, coronary artery disease, and stable angina (n=917). Seattle Angina Questionnaire (SAQ) vs. Daily angina diary was evaluated on Correlation between SAQ angina frequency and daily diary angina frequency (Correlation -0.64, 95% CI -0.68 to -0.60). The Seattle Angina Questionnaire angina frequency domain strongly correlated with daily diary entries of angina frequency (r = -0.64; 95% CI, -0.68 to -0.60) in patients with stable angina.
