Objective: We aimed to study the long-term development of health-related quality of life (HR-QoL) in patients with peripheral arterial disease after they underwent peripheral bypass surgery and to evaluate the influence of adverse vascular events that occurred during follow-up.
Methods: We compared current HR-QoL scores with previous measurements in patients who participated in the Dutch Bypass and Oral Anticoagulants or Aspirin (BOA) Study between 1995 and 1998 after they underwent infrainguinal bypass surgery. Patients from six centers that contributed most to the Dutch BOA Study (n = 482) were followed up retrospectively from 1995 up to 2009.
Results: At a mean follow-up of 11 years since BOA randomization, 165 of the 482 patients were alive of whom 123 (75%) completed the EQ-5D and RAND-36 questionnaires. Fifty-three patients completed the questionnaires three times: at BOA entry, at BOA close-out, and at BOA long-term follow-up. In these patients the HR-QoL scores decreased over time, especially for the physical health dimension. In comparison with the general population, matched for age and gender, the HR-QoL scores at both BOA entry and long-term follow-up were substantially lower, even if the patient's graft was patent and no other vascular events had occurred. The occurrence of an adverse vascular event worsened the physical health state further.
Conclusions: The physical HR-QoL in patients with peripheral arterial disease (PAD) after peripheral bypass surgery was highly impaired, independent of graft patency, and deteriorated further over time. An adverse vascular event worsened the physical health state and underlined the importance of atherosclerotic risk management as well as stimulation of physical activity in patients with peripheral arterial disease to preserve HR-QoL.
