Abstract

Background— Angina in patients with coronary artery disease is associated with worse quality of life; however, the relationship between angina frequency and resource utilization is unknown. Methods and Results— Using data from the MERLIN-TIMI 36 trial, we assessed the association between the extent of angina after an acute coronary syndrome (ACS) and subsequent cardiovascular resource utilization among 5460 stable outpatients who completed the Seattle Angina Questionnaire at 4 months after an ACS and who were then followed for an additional 8 months. Angina frequency was categorized as none (score, 100; 2739 patients), monthly (score, 61 to 99; 1608 patients), weekly (score, 31 to 60; 854 patients), and daily (score, 0 to 30; 259 patients). Multivariable regression models evaluated the association between angina frequency and overall costs attributable to cardiovascular hospitalizations, outpatient visits and procedures, and medications. As compared with no angina, overall costs increased in a graded fashion with higher angina frequency—no angina, $2928 (reference); monthly angina, $3909 (adjusted relative cost ratio, 1.29; 95% CI, 1.21 to 1.39); weekly angina, $4558 (adjusted relative cost ratio, 1.52; 95% CI, 1.48 to 1.67); and daily angina, $6949 (adjusted relative cost ratio, 2.32; 95% CI, 2.01 to 2.69; P for trend <0.001). Differences in costs were attributable primarily to higher rates of ACS hospitalization and coronary revascularization among patients with more severe angina. Conclusion— Among stable outpatients after ACS, a direct graded relationship was found between higher angina frequency and healthcare costs. As compared with patients without angina, patients with daily angina had a >2-fold increase in resource utilization and incremental costs of $4000 after 8 months of follow-up.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
