Previous myocardial infarction was the strongest independent predictor of 30-day mortality following surgical repair of non-ruptured abdominal aortic aneurysm (OR 8.8).
Cohort (n=69)
No
A simple risk score model incorporating female gender, previous myocardial infarction, and symptomatic clinical course can effectively stratify 30-day mortality risk in patients undergoing surgical repair of non-ruptured abdominal aortic aneurysms.
Effect estimate: OR 8.8 (95% CI 1.02-76.06)
Absolute Event Rate: 20.6% vs 2.9%
p-value: p=0.016
The aim of this prospective study of patients undergoing repair of non-ruptured abdominal aortic aneurysm between 1999 and 2003 was to evaluate and compare risk factors for mortality after surgery, to determine a complex of informative factors for lethal outcome, and to define patient risk groups. Logistic regression analysis revealed a complex of informative factors, including female gender, previous myocardial infarction, age greater than 75 years, and clinical course of abdominal aortic aneurysm as important indicators for lethal outcome. A risk score model identified low-, moderate- and high-risk groups with mortality rates of 2.9%, 8.0% and 44.4%, respectively.
Urbonavičius et al. (Wed,) conducted a cohort in Non-ruptured abdominal aortic aneurysm (n=69). Surgical repair was evaluated on 30-day post-operative mortality (previous myocardial infarction vs no previous myocardial infarction) (OR 8.8, 95% CI 1.02-76.06, p=0.016). Previous myocardial infarction was the strongest independent predictor of 30-day mortality following surgical repair of non-ruptured abdominal aortic aneurysm (OR 8.8).
