ABSTRACT
Objective To explore the potential risk factors for aortic and mitral valve calcification in maintenance hemodialysis(MHD)patients. Methods Patients on MHD for at least 6 months.aged≥1 8 years without history of surgery or catheter for heart valve disease were enrolled in the study.Echocardiographic examination was performed to detect the calcification.The risk factors for aortic and mitral valve calcification were analyzed by Logistic regression. Results One hundred and eighty-one MHD patients(98 men and 83 women)were enrolled in the study.Of all the patients,aortic or mitral valve calcification was found in 94 patients(5 1.9%),aortic valve calcification in 90 patients(49.7%),mitral valve calcification in 30 patients(16.6%),aortic and valve calcification in 26 patients(14.4%).Multivariate Logistic regression showed that age(β=5.52,P=0.007),dialysis duration(β=6.99,P=0.039)and pre-albumin(β=-12.616,P=0.004)were independently correlated with aortic valve calcification.Mitral valve calcification was independently correlated with dialysis duration(β=6.057,P=0.002),history of primary hypertension(β=3.054,P=0.008),hemoglobin(β=-0.061,P=0.035)and β2 microglobulin(β=7.63,P=0.01).While the correlation between mitral valve calcification and age was borderline significant(β=0.085,P=0.05).Conclusions Valve calcification is prevalent in MHD patients,and aortic valve calcification is more common than mitral valve calcification.Age,dialysis duration and low serum pre-albumin are independent risk factors for aortic valve calcification.The risk factors for mitral valve calcification include age,dialysis duration,history of primary hypertension,anemia and high serum β2 microglobulin.
