Abstract:
Objective To analyze the risk factors of aortic valve calcification,and discuss its correlation with coronary artery disease.Methods A total of 188 patients who underwent coronary angiography (CAG) and transthoracic echocardiography (TTE) were divided into two groups:101cases with aortic valve calcification (AVC) and 87 cases without AVC (NAVC).General data such as sex,age,height,weight and hypertension history,results of blood test such as glucose,lipid and homocysteine(HCY)level were recorded.Results In AVC versus NAVC group,age were (67.0±9.0) years vs.(59.4 ± 6.9) years (t =6.74,P =0.000),men were 36 cases (35.6％) vs.44 cases (50.6％) (t=4.26,P=0.039),hypertension patients were 72 cases (71.3％) vs.50 cases (57.5％)(x2=3.92,P=0.048),total cholesterol were (5.4 ± 1.0) mmol/L vs.(4.5 ± 1.0)mmol/L (t =5.70,P=0.000),triglyceride were (2.2 ± 1.1 ) mmol/L vs.( 1.6 ± 0.8) mmol/L (t =4.04,P =0.000),HCY were (17.6±8.8) μmol/L vs.(14.9±6.6) μmol/L (t=2.86,P=0.028),respectively.One-way analysis showed that age,sex,hypertension,total cholesterol,triglyceride had relationship with aortic valve calcification.When we divided the cases into two groups (with and without coronary disease),there is no significant difference in HCY(t=0.88,P=0.382) between the two groups.Logistic regression indicated that age,total cholesterol,triglycerides,HCY were independent risk factors of aortic valve calcification,the incidence of aortic valve calcification was related with the severity of coronary artery lesion (x2 =9.48,P =0.024 ).Conclusions The independent risk factors of aortic valve calcification are age,cholesterol,triglyceride,HCY.Higher incidence of aortic valve calcification may result in greater severity coronary artery lesion.
