Superior mesenteric artery calcification is associated with cardiovascular risk factors, systemic calcified atherosclerosis, and increased mortality.

Atherosclerosis is a major risk factor for morbidity and mortality. However, epidemiologic data are sparse regarding risk factors for superior mesenteric artery calcification (SMAC), the association between SMAC and disease in other arterial beds, or the independent contribution of SMAC to risk of mortality. The objective of this study was to test the hypothesis that presence and extent of SMAC are associated with cardiovascular disease (CVD) risk factors, calcification in other arterial beds, and both cardiovascular and all-cause mortality, independent of classic risk factors and calcification in other arterial beds.
