目的探讨经重组人脑钠肽(recombinant human brain natriuretic peptide,rhBNP)治疗后,射血分数正常心力衰竭(heart failure with normal ejection fraction,HFNEF)患者的血浆脑钠肽前体(pro-brain natriuretic peptide,proBNP)浓度及...目的探讨经重组人脑钠肽(recombinant human brain natriuretic peptide,rhBNP)治疗后,射血分数正常心力衰竭(heart failure with normal ejection fraction,HFNEF)患者的血浆脑钠肽前体(pro-brain natriuretic peptide,proBNP)浓度及临床症状的变化。方法入选51例HFNEF患者(纽约心脏协会心功能Ⅲ、Ⅳ级),其中21例在常规治疗的基础上加用rhBNP治疗4~7 d,治疗前、后分别检测血浆proBNP浓度,并与仅用常规治疗的对照组(30例)比较。分析治疗前、后血浆proBNP浓度及临床症状变化。结果治疗组与对照组总有效率分别为95.2%和93.3%,差异无统计学意义(P>0.05)。两组治疗后血浆proBNP浓度与治疗前比较都有下降,差异有统计学意义(P<0.05);且治疗组治疗后血浆proBNP浓度显著低于与对照组,差异有统计学意义[1 297.5 pg/mL vs.2 037.8 pg/mL,P<0.05]。结论rhBNP可降低HFNEF患者血浆proBNP浓度,有效改善患者症状。展开更多
