Recent epidemiological data indicate that the concentration of circulating calcium is related to cardiovascular disease (CVD) mortality. We determined whether serum calcium level is related to arterial stiffness and 10-year CVD risk calculated by Framingham risk score (FRS). We examined the association of normal-range serum calcium level with arterial stiffness and FRS in 565 Korean adults participating at the Health Promotion Center of Gangnam Severance Hospital between March 2016 and May 2017. High brachial-ankle pulse wave velocity (baPWV) was defined as >1460 cm/s, and high FRS was defined as ≥10 percent for 10-year CVD risk. Odds ratios (ORs) and 95% confidence intervals (95% CIs) for high baPWV and high FRS were calculated using multiple logistic regression analysis after adjusting for confounding variables. The OR (95% CI) for high baPWV was 3.91 (1.15-7.36) per 1 mg/dL increment of serum calcium after adjusting for age, sex, body mass index, smoking status, exercise regularity, alcohol consumption, mean blood pressure, fasting plasma glucose, triglyceride, HDL-cholesterol, C-reactive protein, γ-glutamyltransferase, uric acid level, phosphate level, potassium level, and presence of hypertension, diabetes and dyslipidemia medications (P = 0.024). A positive association between serum calcium level and high FRS was also observed after adjusting for the same covariables (OR, 3.54 [95% CI, 1.01-12.44], P = 0.048). Serum calcium level was independently and positively associated with baPWV and 10-year CVD risk estimates. Early detection of higher serum calcium level may be important for the assessment of arterial stiffness and future risk of a cardiovascular event.
