Coronary Artery Disease

Findings The serum 25(OH)D level of CAD patients was 18.2 10.6 ng/ml. The SYNTAX scores were 27.8 8.5. In a multivariate linear regression analysis (adjusted for age, high-sensitivity C-reactive protein, SYNTAX score, parathyroid hormone, body mass index, haemoglobin and creatinine), the serum 25(OH)D level showed a negative correlation with SYNTAX score and high-sensitivity C-reactive protein (hsCRP) level. Logistic regression analysis identified 25(OH)D as an independent factor related to high SYNTAX scores. Patients whose vitamin D levels were in the lowest 25(OH)D category ( 30 ng/ml).
