ABSTRACT
Angina is a common symptom in patients with coronary artery disease (CAD); however, its impact on patients' quality of life over time is not well understood. We sought to determine the longitudinal association of angina frequency with quality of life and functional status over a 5-year period. We used data from the Heart and Soul Study, a prospective cohort study of 1,023 outpatients with stable CAD. Participants completed the Seattle Angina Questionnaire (SAQ) at baseline and annually for 5 years. We evaluated the population effect of angina frequency on disease-specific quality of life (SAQ Disease Perception), physical function (SAQ Physical Limitation), perceived overall health, and overall quality of life, with adjusted models. We evaluated these associations within the same year and with a time-lagged association between angina and quality of life reported 1 year later. Generalized estimating equation models were used to account for repeated measures and within-subject correlation of responses. Over 5 years of follow-up, patients with daily or weekly angina symptoms had lower quality of life scores (52 vs 89, p <0.001) and greater physical limitation (61 vs 86, p <0.001) after adjustment. Compared with patients with daily or weekly angina symptoms, those with no angina symptoms had 2-fold greater odds of better quality of life (odds ratio 2.39, 95% confidence interval 1.76 to 3.25) and 5-fold greater odds of better perceived overall health (odds ratio 5.45, 95% confidence interval 3.85 to 7.73). In conclusion, angina frequency is strongly associated with quality of life and physical function in patients with CAD. Even after modeling to adjust for both clinical risk factors and repeated measures within subjects, we found that less frequent angina symptoms were associated with better quality of life.
