Abstract: BACKGROUND: Patients with abdominal aortic aneurysm (AAA) are at significant risk of cardiovascular (CV) events. Recent implementation of AAA-screening means thousands of patients are now diagnosed with small-AAA; however, CV risk factors are not always addressed. This study aimed at assessing and quantifying the CV characteristics of patients with small AAA following the introduction of screening programmes. METHODS: CV profiles of 384 men with a small AAA (<55 mm diameter) were assessed through the United Kingdom Aneurysm Growth Study (UKAGS), a nationwide prospective cohort study of men with small AAA. A prospective local cohort of an additional 142 patients with small AAA with available blood pressure (BP) and lipid profiles was also included and followed-up for 1 year. RESULTS: In the UKAGS population, 54% were current and 30% ex-smokers; 58% were hypertensive and 54% hypercholesterolaemic. In the local group, 54% were current and 40% were ex-smokers, and 94% were hypertensive. Patients were not more likely to receive CV medication after entering AAA surveillance in either group. All local patients were clustered "high-risk" for future CV events based on the Framingham score (mean 21.8%, 95% CI 20.0-23.6), JBS-2 (16.3%, 14.7-17.9) and ASSIGN (25.2%, 22.7-27.7). No change was seen in systolic BP levels between baseline and 1 year (140.9 mmHg vs. 142.5 mmHg, p=.435). A rise was seen in cholesterol (4.0 mmol-4.2 mmol, p<.0001) values at 1 year. CONCLUSIONS: This study suggests that patients with small AAA are at significant risk for developing CV events and this is not currently addressed, which is evident by the "high-risk" CV risk profiles of these patients despite being in AAA surveillance. Design and implementation of a CV risk reduction programme tailored for this population is necessary.
