Abstract:Objective To analyze the association of 25 hydroxyvitamin D and osteoprotegerin with chronic heart failure. Methods Totally 148 patients with chronic heart failure were divided into group II, grade III and grade IV according to cardiac function. 42 cases of patients without heart failure were selected as control group. The liver and kidney function, blood lipid, blood glucose, alkaline phosphatase, levels of 25-hydroxyvitamin D and osteoprotegerin were recorded in all subjects. The left ventricular end diastolic volume and left ventricular ejection fraction were obtained by heart ultrasonography. Results A total of 25 hydroxyvitamin D was significantly lowered while alkaline phosphatase and osteoprotegerin levels were highered in patients with heart failure than those in patients without heart failure. The level of 25 hydroxyvitamin D was the lowest in patients with grade IV cardiac function (P?0.05). Left ventricular end diastolic diameter and osteoprotegerin were increased while left ventricular ejection fraction was decreased significantly in patients with chronic cardiac failure when compared with those in patients without heart failure or healthy controls (P?0.05). The correlation analysis showed that 25 hydroxyvitamin D was negatively correlated with uric acid and NT-proBNP. We found the osteoprotegerin was negatively correlated with the left ventricular ejection fraction while positively correlated with NT-proBNP and alkaline phosphatase (P < 0.05). Conclusions High expression of osteoprotegerin and low expression of 25-hydroxyvitamin D in patients with chronic heart failure correlates with NT-proBNP, left ventricular ejection fraction and alkaline phosphatase.
