Relationship Between Coronary Atherosclerosis in Coronary Computed Tomography Angiography and Serum Vitamin D Level


Relationship Between Coronary Atherosclerosis in Coronary Computed Tomography Angiography and Serum Vitamin D Level

Ah-Young Lee et al. Osteoporos Sarcopenia.


Objectives: Vitamin D deficiency has been shown to influence the development of some cardiovascular disease. In this study, the association between the existence of coronary artery plaque and vitamin D was examined among participants who were not previously diagnosed with coronary artery disease.

Methods: A total of 339 participants (246 men and 93 women) who visited a health examination center for check-up including blood test for serum vitamin D level and coronary computed tomography angiography (CCTA) were selected for this study.

Results: Among the total 339 participants, 106 displayed coronary artery plaques. The serum 25-hydroxy vitamin D (25(OH)D) level of the group with plaque was lower than that of the group without (17.7 ± 7.72 ng/mL vs. 19.6 ± 7.12 ng/mL, P = 0.0316). The group with plaque had higher incidence rates of diabetes mellitus, hypertension, and dyslipidemia than that without (P = 0.0078, P = 0.0065, and P = 0.0174, respectively). The former displayed higher serum glucose and glycated hemoglobin levels than the latter (P = 0.0055 and P = 0.0137, respectively). The group with plaque showed higher systolic and diastolic blood pressure than that without (P < 0.0001 and P = 0.0012, respectively). Stepwise multivariate logistic regression analysis revealed that 25(OH)D (coefficient, -0.06; odd ratio, 0.9433; 95% confidence interval, 0.8967-0.9924), age, and sex were independently related with presence of coronary artery plaque.

Conclusions: Relatively low vitamin D level was observed among participants with plaque, which was determined through CCTA during a health examination. Plaque formation and serum 25(OH)D level showed inverse relationship.
