  • Correlation Between Inflammation-related Gene Polymorphisms and Efficacy of Warfarin Therapy after Heart Valve Replacement Surgery

    ObjectiveTo clarify the relationship between the G/C polymorphism of inflammatory gene matrix metalloproteinase-2 (MMP2) and warfarin therapy after cardiac valve replacement (CVR). MethodsWe finally identified 96 patients who received additional warfarin therapy after CVR as a trial group and 78 patients without the warfarin therapy as a control group. Gene sequencing techniques were adopted to determine single nucleotide polymorphism allele. We analyzed genotype and clinical features of the two groups and explored the relationship between the different MMP2 geno-types and warfarin therapy after CVR. Logistic regression was used to analyze the correlation between genotypes and risk factors after CVR and Kaplan-Meier survival curves were performed to analyze the survival time and efficacy of patients carrying MMP2 GC and GG genotypes. ResultsThe distribution of MMP2 genotype in patients receiving warfarin therapy after surgery was different from that in patients without warfarin therapy. The results of multivariate logistic regression analysis showed that GC and GG genotypes were risk factors of complications of CVR. The proportion of GG genotype was higher in the patients with postoperative complications compared with those without. The survival time of patients carrying genotype MMP2 GG was shorter than those carrying GC genotype (P < 0.05), which reveals that the level of MMP2 GG genotype was associated with the prognosis. ConclusionG allele of MMP2 is a risk factor of complications following CVR. GG genotype is relevant to CVR and prognosis, which can be regarded as a risk factor post CVR.
