Abstract

Objectives: Nowadays, vitamin D3 (VitD3) deficiency is among the most common dietary deficiencies around the world. Researchers have paid more attention to VitD3 because it is a vital element of the body and has a plausible relationship with various diseases such as diabetes mellitus type II. This study was conducted to examine the prevalence of vitamin D3 deficiency and its relationship with blood sugar levels in people with diabetes undergoing coronary artery bypass grafting (CABG).

Methods: An observational study was conducted in 2017 in Shahid Madani Hospital, Tabriz, Iran, for 8 months. Due to the use of census sampling, only 115 patients with diabetes and open-heart surgery were enrolled in the study. A questionnaire collected information on the participants' demographics, medical history, VitD3 levels and blood glucose levels. Data were analyzed using SPSS ver. 25. Independent t-test was used to compare quantitative data, and chi-square test was used to compare categorical variables.

Results: One hundred and fifteen out of 348 patients who had CABG surgery were diabetic. Moreover, 24.7% of patients with diabetes had VitD3 deficiency. The results of the coefficient-correlation test indicated that there was a significant relationship between the mean blood glucose level and VitD3 level (p < 0.05).

Conclusions: The results of this study suggest that patients with diabetes can improve their blood glucose control after CABG surgery by taking sufficient VitD3. Therefore, it should be considered as a principle of the hospital operation to prescribe VitD3 prior to surgery for these patients.
