Abstract

BACKGROUND:

Anxiety is common among patients presenting with suspected coronary artery disease (CAD). In a sample of women with signs and symptoms of ischemia, we examined three anxiety markers as predictors of CAD endpoints including: 1) cardiac symptom indicators; 2) angiographic CAD severity; and 3) healthcare utilization (cardiac hospitalizations and 5-year cardiovascular [CVD] healthcare costs).

METHODS:

Participants completed a baseline protocol including coronary angiogram, cardiac symptoms, psychosocial measures and a median 5.9-year follow-up to track hospitalizations. We calculated CVD costs based on cardiac hospitalizations, treatment visits, and CVD medications. Anxiety measures included anxiolytic medication use, Spielberger Trait Anxiety Inventory (STAI) scores, and anxiety disorder treatment history.

RESULTS:

The sample numbered 514 women with anxiety measure data and covariates (mean age=57.5 [11.1]). One in five (20.4%) women reported using anxiolytic agents. Anxiety correlated with cardiac symptom indicators (anxiolytic use with nighttime angina and nitroglycerine use; STAI scores and anxiety disorder treatment history with nighttime angina, shortness of breath, and angina frequency). Anxiety disorder treatment history (but not STAI scores or anxiolytics) predicted less severe CAD. Anxiolytic use (but not STAI scores or anxiety disorder treatment history) predicted hospitalizations for chest pain and coronary catheterization (HRs=2.0, 95% CIs=1.1-4.7). Anxiety measures predicted higher 5-year CVD costs (+9.0-42.7%) irrespective of CAD severity.

CONCLUSIONS:

Among women with signs and symptoms of myocardial ischemia, anxiety measures predict cardiac endpoints ranging from cardiac symptom severity to healthcare utilization. Based on these findings, anxiety may warrant greater consideration among women with suspected CAD.
