The association between coronary artery calcification and colorectal adenoma
1Center for Health Promotion, John Hopkins University, Bloomberg School of Piblic Helath Baltimore, Maryland, USA.
Background/Aims:
Both colorectal neoplasm and coronary artery disease are prevalent diseases worldwide and share several risk factors. The aim of this study was to investigate the association between coronary artery calcification and prevalence of colorectal adenoma.
Methodology:
We retrospectively evaluated 3,092 subjects who underwent colonoscopy and coronary artery calcium computed tomography (CT) on the same day or within a 3-month interval, during routine check-ups between January 2006 and June 2009 at the Center for Health Promotion of the Samsung Medical Center. Multivariate logistic regression analysis was used to calculate adjusted odds ratios (ORs).
Results:
Colorectal adenomas were detected in 1,067 (34.5%) of the 3,092 subjects, including 536 (41.0%) individuals with and 531 (29.7%) without coronary calcification (p<0.001). Multiple logistic regression analysis showed that the presence of coronary artery calcification (OR=1.346; 95% confidence interval [CI]=1.122-1.614), age ≥50 years (OR=1.516; 95% CI=1.256-1.829), waist circumference of 90-99cm (OR=1.364; 95% CI=1.008-1.844) and current smoker (OR=1.266; 95% CI=1.045-1.534) were associated with the prevalence of colorectal adenoma.
Conclusions:
The prevalence of colorectal adenoma is significantly higher in patients with coronary artery calcification. Our results support positive relationship between coronary artery disease and colorectal adenoma.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
