ABSTRACT
Objective:To study the correlation among lipoprotein (a) [Lp (a)] ,its gene polymorphism and degenera‐tive calcific aortic valve disease (DCAVD) .Methods :From Feb 2010 to Jan 2014 ,a total of 164 DCAVD cases trea‐ted in our hospital were enrolled as DCAVD group ,another 164 healthy subjects undergoing physical examination in the same period were selected as normal control group .Relationship among Lp (a) level ,its gene polymorphism and aortic valvular calcification was compared and analyzed ,and Logistic regression analysis was used to analyze in‐dependent risk factors of DCAVD . Results :Lp (a ) gene possesses four point mutations in population , namely rs10455872 ,rs6415084 ,rs3798221 and rs7770628. In DCAVD group ,Lp (a) level of AG genotype was significantly higher than that of AA genotype [ (325.5 ± 108.2) mg/L vs .(211.7 ± 135.4) mg/L] in rs10455872 gene pheno‐type ,Lp (a) level of CC+TT genotype was significantly higher than that of CT genotype [ (287.9 ± 144.1) mg/L vs .(240.7 ± 127.2) mg/L] in rs6415084 gene phenotype ,and Lp (a) level of TT+ CC genotype was significantly higher than that of CT genotype [(304.1 ± 124.1) mg/L vs .(226.8 ± 101.6) mg/L] in rs7770628 gene phenotype , P<0.05 or <0.01 ;patient′s percentage of valvular calcification of AG genotype was significantly higher than that of AA genotype (90.0% vs .61.7% ) in rs10455872 , patients percentage of valvular calcification of CC +TT geno‐type was significantly higher than that of CT genotype (83.8% vs .66.7% ) in rs6415084 ,and patient′s percentage of valvular calcification of TT+CC genotype was significantly higher than that of CT genotype (87.3% vs .63.4% ) in rs7770628 , P<0.05 or <0.01. Logistic regression analysis indicated that rs10455872 ,rs6415084 ,rs7770628 and Lp (a) level were independent risk factors for valvular calcification of DCAVD (OR=1.67~2.31 , P<0.01 all) . Conclusion :Lp (a) gene polymorphism (rs10455872 ,rs6415084 and rs7770628) and plasma Lp (a) level are signifi‐cantly correlated to valvular calcification of DCAVD ,which may be susceptible genes for DCAVD occurrence .
