ABSTRACT
Objective@#To investigate the correlation between serum asymmetric dimethylarginine (ADMA) and cystatin C (CysC) in degenerative calcific aortic valvular disease and its clinical application value.@*Methods@#One hundred and eighty patients with degenerative calcific aortic valvular disease who were treated in Beijing Luhe Hospital Affiliated to Capital Medical University from June 2016 to June 2018 were selected as the study subjects, and another 82 healthy subjects from the same hospital in the same period were selected as the control group. Serum ADMA and CysC levels were detected by enzyme-linked immunosorbent assay and latex-enhanced immunoturbidimetric assay. Risk factors of degenerative calcific aortic valvular disease were analyzed by Logistic regression analysis. Evaluation of the diagnostic efficacy of serum ADMA and CysC for degenerative calcific aortic valvular disease was used by receiver operating characteristic curve.@*Results@#There were no significant differences in the general data between the two groups in terms of age, gender, body mass index, drinking history, smoking history, and history of hypertension (P>0.05). The systolic blood pressure(SBP), diastolic blood pressure (DBP), heart rate (HR), total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterin(LDL-C), CysC and ADMA levels of the study group were significantly higher than those of the control group [(131.51 ± 19.09) mmHg (1 mmHg=0.133 kPa) vs. (126.48 ± 16.68) mmHg, (91.11 ± 16.35) mmHg vs. (86.89 ± 10.71) mmHg, (74.39 ± 15.22) beats/min vs. (70.09 ± 13.01) beats/min, (4.51 ± 1.12) mmol/L vs. (4.15 ± 0.92) mmol/L, (1.91 ± 0.63) mmol/L vs. (1.60 ± 0.65) mmol/L, (2.59 ± 1.13) mmol/L vs. (2.27 ± 0.85) mmol/L, (1.01 ± 0.22) mg/L vs. (0.79 ± 0.16) mg/L, (20.17 ± 6.38) ng/L vs. (11.88 ± 4.22) ng/L], and left ventricular ejection fraction (LVEF), high density lipoprotein cholesterin (HDL-C) levels were significantly lower than those of the control group [(56.45 ± 9.21)%vs. (60.87 ± 10.02)%, (1.56 ± 0.63) mmol/L vs. (1.76 ± 0.62) mmol/L], there were significant differences (P<0.05). Logistic multivariate regression analysis showed that serum CysC and ADMA were independent risk factors for degenerative calcific aortic valvular disease (P<0.05). Receiver operator characteristic (ROC) curve analysis showed that area under curve (AUC) of serum CysC for degenerative valvular heart disease was 0.785, with a sensitivity of 71.67%, and a specificity of 73.17%. The AUC of serum ADMA for degenerative valvular heart disease was 0.862, with a sensitivity of 71.67%, and a specificity of 87.80%. The AUC of serum CysC combined with ADMA in the diagnosis of degenerative valvular heart disease was 0.910, with a sensitivity of 85.56%, and a specificity of 84.15%, which was significantly higher than the two alone (Z=4.897 and 3.335, P<0.05).@*Conclusions@#Serum ADMA is positively correlated with CysC in patients with degenerative valvular heart disease, and can be used as diagnostic serum markers for degenerative calcific aortic valvular disease. It has clinical reference value for improving the diagnosis of degenerative calcific aortic valvular disease.
