Identifying abdominal aortic aneurysm risk factors in postmenopausal women.
Evaluation of: Lederle FA, Larson JC, Margolis KL et al.: Abdominal aortic aneurysm events in the Women's Health Initiative: cohort study. Br. Med. J. 337, A1724 (2008). A linked cohort study of 161,808 postmenopausal women aged 50-79 years enrolled in the Women's Health Initiative was conducted during which participants were followed for the incidence of abdominal aortic aneurysm repair or rupture. This study evaluated the association between potential risk factors and subsequent abdominal aortic aneurysm events in women. A total of 467 women reported a diagnosis of abdominal aortic aneurysm before entering the study or during participation, with 184 aneurysm-related events identified. Abdominal aortic aneurysm events were strongly associated with age and smoking and negatively associated with diabetes and baseline use of postmenopausal hormone supplementation. Previous studies investigating abdominal aortic aneurysm have focused primarily on men, with little reliable information available on women. This study contributes a large female cohort to provide better insight into gender-specific abdominal aortic aneurysm risks and disease associations.
