Prevalence of Abdominal Aortic Aneurysm in Patients with Coronary Artery Stenosis Undergoing Angiography from 2011 to 2016

Abstract

An abdominal aortic aneurysm (AAA) is an abnormal local dilation of the aorta. The relationship between coronary artery disease (CAD) and the AAA is well established. This study evaluated the prevalence of AAAs in patients with CAD who underwent angiography in a hospital. Between 2011 and 2016, a total of 576 patients with coronary artery stenosis and a stenosis level greater than 50% in at least one of their coronary arteries were referred for angiography. Patient data were collected from medical records, and a checklist was created to document demographic information, underlying medical conditions, and ultrasound findings. Data were analyzed using either the chi-square or Fisher's exact test, depending on the specific variables being examined. The prevalence of AAAs among 576 patients with CAD was 6.3%. The difference in the distribution of AAAs in patients based on smoking (p = 0.003) and high blood pressure history (p < 0.001) was statistically significant. AAAs in patients with CAD showed no significant difference in hyperlipidemia (p = 0.13) and diabetes (p = 0.06). The prevalence of AAA was not associated with an increase in the number of involved vessels (p = 0.06). The prevalence of AAAs in patients with CAD angiography was found to be 6.3%. The prevalence increased significantly with age, and females had a higher prevalence than males. The prevalence increased with the increased number of involved vessels but not significantly. The study highlights the importance of prevention and early detection to avoid rupture and high mortality rates.
