Objective To discuss fluvastatin intervention on ventricular remodeling and plasma brain natri-uretic peptide( BNP) levels in dilated cardiomyopathy( DCM) .Methods 64 cases of DCM patients were selected and randomly divided into the intervention group and control group,each group in 32 cases.Both groups were treated with conventional drug therapy, including angiotensin-converting enzyme inhibitors,β-blockers, diuretics, etc.In conven-tional drug treatment intervention group based on the use of fluvastatin 40mg/d.Intervention in both groups before and 6 months after the intervention,plasma BNP levels were examined and ventricular remodeling indicators,analyzed and compared using Pearson Univariate correlation of each index.Results The total efficiency of the intervention group was higher than that of the control group(87.51%vs 65.63%,χ2 =4.730,P<0.05);6 months after the interven-tion groups,plasma BNP levels were significantly decreased left ventricular ejection fraction(LVEF),left ventricular end systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD) and relative wall thickness(RWT) were significantly improvements.BNP levels and LVEF and RWT was negatively correlated( r=-0.45,-0.39,all P<0.05);Positively correlated with LVESD and LVEDD showed(r=0.35,0.44,all P<0.05),the difference was statistically significant.Conclusion Fluvastatin intervention can significantly reduce plasma BNP levels in DCM and improve ventricular remodeling.
