Objective To investigate the early intervention to improve calcium and phosphorus metabolism in chronic kidney disease patients left ventricular hypertrophy. Methods 116 cases of non-dialysis patients with chronic kidney disease were randomly divided into 3,4-intervention group and control group, intervention group patients with calcium and phosphorus metabolism in early intervention were observed in patients with calcium, phosphorus, and left ventricular mass index changes. Results Patients in the intervention group after the intervention of phosphorus,calcium and phosphorus product,serum parathyroid hormone were significantly lower than the control group,the difference was all statistically significant (all P＜0.05 );intervention group of LVMI was significantly lower than before the intervention, but also significantly lower than the control group, the difference was statistically significant (P＜0.05). Conclusion Patients with chronic renal calcium and phosphorus metabolism of early intervention can improve symptoms in patients with left ventricular hypertrophy is beneficial to the improvement of patients with the disease.
