Initial functional and economic status of patients with multivessel coronary artery disease randomized in the Bypass Angioplasty Revascularization Investigation (BARI).
Randomized trials of coronary angioplasty and bypass surgery have hypothesized that these procedures will have equivalent long-term rates of death and myocardial infarction. Functional status, quality of life, employment, and healthcare cost will therefore be critical measures of the efficacy of these alternative revascularization procedures. Patients at 7 sites in the Bypass Angioplasty Revascularization Investigation (BARI) were enrolled in an ancillary Study of Economics and Quality of Life (SEQOL). Physical function was assessed by the Duke Activity Status Index and emotional status by the Mental Health Inventory. Employment patterns and health care utilization were also measured at study entry and at 3-month intervals in follow-up. The 934 patients enrolled in SEQOL were similar to the 895 remaining BARI randomized patients. Most patients (63%) aged < or = 64 years were working, and almost all working patients (96%) intended to return to work. Patients aged > or = 65 years had lower household incomes but better health insurance coverage. Overall health ratings were significantly correlated with both physical and emotional status (p < 0.001). Patients enrolled in SEQOL are representative of the overall BARI population. Data collected in SEQOL will provide a detailed picture of the physical, emotional, and economic well-being after coronary angioplasty and bypass surgery.
