Abstract: Objective To investigate the characteristics and influencing factors of vascular calcification in maintenance hemodialysis patients. Methods  The clinical data of 126 patients with maintenance hemodialysis were retrospectively analyzed. The indexes of maintaining blood dialysis patients and the effect of  risk factors for vascular calcification were analyzed. Results  The two groups showed significant differences in gender， age， diabetes mellitus， hypertensive history， fibroblast growth factor (FGF23)， daily dose of calcium and corrected serum calcium and multiplication of calcium and phosphorus levels （P＜0.05）. Age， dialysis age， diabetes mellitus and high sensitivity Creactive protein (hsCRP) were independent risk factors for   vascular calcification  in patients with maintenance hemodialysis. Conclusion  The patients with vascular calcification is common in hemodialysis， and gender， age， diabetes  history， hypertension， correction of calcium， calcium and phosphorus product are all  risk factors of  vascular calcification.
