ABSTRACT

Introduction: Although vitamin D has a major role at the skeletal mineralization, it has been implicated at cardio vascular system, owing to abundance of its receptor there. Atherosclerosis is the most presenting symptom of such system that warrants the urge to detect the effect of vitamin D serum level changes in progression of the atherosclerosis.
Objectives: assess the correlation between vitamin D level and coronary artery findings using MDCT.
Patients and methods: 250 patients were included in our study, all of them underwent MDCT for coronary artery angiography, and then the findings were compared with vitamin D serum levels.
Results: 4 % of all participants (n=10) had vitamin D deficiency, 44 % (n=110) had insufficient levels of vitamin D, 52 % have sufficient vitamin D level (n=130). There is significant positive correlation between serum vitamin D levels and coronary artery calcium score (CACS) with P
