The Economic Burden of Angina in Women With Suspected Ischemic Heart Disease: Results From the National Institutes of Health-National Heart, Lung, and Blood Institute-Sponsored Women's Ischemia Syndrome Evaluation -- Shaw et al. 114 (9): 894 -- Circulation:
"Background— Coronary angiography is one of the most frequently performed procedures in women; however, nonobstructive (ie, <50% style="font-weight: bold;">Methods and Results— A total of 883 women referred for coronary angiography were prospectively enrolled in the National Institutes of Health–National Heart, Lung, and Blood Institute–sponsored Women’s Ischemia Syndrome Evaluation (WISE). Cardiovascular prognosis and cost data were collected. Direct (hospitalizations, office visits, procedures, and drug utilization) and indirect (out-of-pocket, lost productivity, and travel) costs were estimated through 5 years of follow-up. Among 883 women, 62%, 17%, 11%, and 10% had nonobstructive and 1-vessel, 2-vessel, and 3-vessel CAD, respectively. Five-year cardiovascular death or myocardial infarction rates ranged from 4% to 38% for women with nonobstructive to 3-vessel CAD (P<0.0001).> 12% for 1-vessel to 3-vessel CAD; P=0.001). For women with nonobstructive CAD, average lifetime cost estimates were $767 288 (95% CI, $708 480 to $826 097) and ranged from $1 001 493 to $1 051 302 for women with 1-vessel to 3-vessel CAD (P=0.0003).
Conclusions— Symptom-driven care is costly even for women with nonobstructive CAD. Our lifetime estimates for costs of cardiovascular care identify a significant subset of women who are unaccounted for within current estimates of the economic burden of coronary heart disease. "
