Abstract

Vitamin D (VD) deficiency is considered an important risk factor for the development of atherosclerosis and aortic aneurysms. The deficiency is claimed to enhance degeneration and remodeling of collagen and elastin fibers in the artery wall, leading to its weakening and progressive dilatation. This study aimed to assess vitamin D status, in outpatients with abdominal aneurysms (AAA) and peripheral artery disease (PAD) not treated with VD, and factors affecting serum 25-OH-D levels. This cross-sectional study involved 59 outpatients with AAA and 150 with PAD. AAA was defined as local dilation of the aorta diameter >30 mm in imaging. None of the patients was prescribed VD containing medicines. Serum 25-OH, iPTH, phosphorus and calcium levels were assessed in all study participants. VD status was categorized according to commonly used cut-offs for serum 25-OH-D (<20 ng/mL - deficiency, <30 ng/mL -insufficiency). Serum 25-OH-D levels were similar in patient with AAA and PAD [1-3Q: 26.2 (18.8-37.6) vs 21.8 (15.9-31.4) ng/mL; p = 0.30], with deficiency noted in 25.4% with AAA and 41.8% with PAD (p < 0.05). Multiple regression analysis revealed that VD deficiency was explained by past stroke episodes [OR = 2.80 (95%CI: 1.22-6.41)]. Se...Continue Reading

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
