Resumen
Background: The incidence of abdominal aortic aneurysms has increased. Its predisposing factors are smoking, high blood pressure and dislipidemia. Progressive aneurysmal enlargement may lead to its rupture, which is associated to a mortality rate above 80%. Aim: To assess the prevalence of abdominal aortic aneurysms in Chilean subjects with cardiovascular risk factors. Subjects and methods: Through announcements in open media we invited individuals aged over 60 years, who smoked, had hypertension and/or had occlusive arterial disease, to participate in a study that included medical history and physical examination. An aortic ultrasound was performed in all subjects in whom the aorta was not palpable or there was a suspicion of dilatation. Aortic diameter over 3 cm was considered aneurysmal. Results: Three hundred fifty six subjects aged 67.1±6.7 years, (73.9% males), were evaluated. The study group included 62% hypertensives, 39% with abnormal lipids and 46% smokers. Known coronary heart disease or peripheral arterial diseases were present in 14% and 10%, respectively. Ultrasound was required in 159 subjects. Aneurysms were detected in 21 persons (5.9%), 7.6% in males and 1.1% in females. The mean transverse diameter of the aneurysm was 4.1 cm (3-7.5). Aneurysm was found in 2.3% of subjects younger than 65 years and 8.3% of subjects aged over 65 years. Conclusions: In this sample the prevalence of abdominal aortic aneurysms was 5.9%, affecting predominantly males, with a notorious increase with advanced age (Rev Méd Chile 2003; 131: 741-7)
