Vitamin B12 deficiency may have indirect cardiovascular effects in addition to hematological and neuropsychiatric symptoms. It was shown that the monocyte count-to-high density lipoprotein cholesterol (HDL-C) ratio (MHR) is a novel cardiovascular marker. In this study, the aim was to evaluate whether MHR was high in patients with vitamin B12 deficiency and its relationship with cardiometabolic risk factors. The study included 128 patients diagnosed with vitamin B12 deficiency and 93 healthy controls. Patients with vitamin B12 deficiency had significantly higher systolic blood pressure (SBP), diastolic blood pressure (DBP), MHR, C-reactive protein (CRP) and uric acid levels compared with the controls (median 139 vs 115\u00a0mmHg, p\u00a0&lt;\u00a00.001; 80 vs 70\u00a0mmHg, p\u00a0&lt;\u00a00.001; 14.2 vs 9.5, p\u00a0&lt;\u00a00.001; 10.2 vs 4\u00a0mg\/dl p\u00a0&lt;\u00a00.001; 6.68 vs 4.8\u00a0mg\/dl, p\u00a0&lt;\u00a00.001 respectively). The prevalence of left ventricular hypertrophy was higher in vitamin B12 deficiency group (43.8%) than the control group (8.6%) (p\u00a0&lt;\u00a00.001). In vitamin B12 deficiency group, a positive correlation was detected between MHR and SBP, CRP and uric acid (p\u00a0&lt;\u00a00.001 r:0.34, p\u00a0&lt;\u00a00.001 r:0.30, p\u00a0&lt;\u00a00.001 r:0.5, respectively) and a significant negative correlation was detected between MHR and T-CHOL, LDL, HDL and B12 (p\u00a0&lt;\u00a00.001 r: \u22120.39, p\u00a0&lt;\u00a00.001 r: \u22120.34, p\u00a0&lt;\u00a00.001 r: \u22120.57, p\u00a0&lt;\u00a00.04 r: \u22120.17, respectively). MHR was high in vitamin B12 deficiency group, and correlated with the cardiometabolic risk factors in this group, which were SBP, CRP, uric acid and HDL. In conclusion, MRH, which can be easily calculated in clinical practice, can be a useful marker to assess cardiovascular risk in patients with vitamin B12 deficiency.
