摘要
目的探讨非那雄胺对合并前列腺增生的老年慢性心力衰竭心室重构及心功能的影响。方法选择2011年1月至2014年10月期间在我科及心血管内科住院的老年慢性心力衰竭合并良性前列腺增生患者80例,所有入选者均接受心衰的最佳药物治疗,心力衰竭临床表现均稳定。良性前列腺增生由泌尿外科专门的医生诊治,根据病人症状及实验室检查决定是否使用非那雄胺。使用非那雄胺组为治疗组40例,未使用非那雄胺组为对照组40例。治疗组加用非那雄胺片每次5mg(1片),每天1次,疗程1年。两组治疗前后行超声心动图检查,测量并计算左室舒张末期内径(LVEDd)、室间隔厚度(IVST)、左室后壁厚度(LVPWT)、每分钟输出量(CO)、左室短轴缩短率(FS)及射血分数(EF),测定血清氨基末端脑钠肽前体(NT-proBNP)水平。比较组内治疗前后上述指标的变化和组间差异。结果 1.治疗组和对照组治疗1年后,两组心肌重构指标LVEDd、IVST、LVPWT、LVM、LVMI均有明显改善,治疗前后差异有统计学意义(P<0.05),治疗组比对照组改善更明显,组间比较差异有统计学意义(P<0.05)。2.治疗1年后,两组心功能指标CO、FS、EF等均有提高,NT-proBNP水平下降,差异均有统计学意义(P<0.05),治疗组比对照组改善更明显,组间比较差异有统计学意义(P<0.05)。结论对于合并前列腺增生的老年慢性心力衰竭患者,服用非那雄胺可能会改善心室重构及心脏功能。
Objective To explore the effect of finasteride on left ventricular remodeling and cardiac function in elderly patient with chronic heart failure(CHF) complicated with benign prostatic hyperplasia(BPH). Methods Eighty eldly patients with CHF combined with BPH were included in the study. All patients received standard heart failure therapy. The clinical symptoms of heart failure is stable. The treatment of benign prostate hyperplasia is required the use of finasteride is decided by the urologist. According to the use of finasteride were divided into treatment group(n=40) and control group(n=40). The treatment group received finasteride tablet, 5mg(one tablet) a time, one time a day, with a treatment course of 1 year. Echocardiogram was applied to the detection of the left ventricular end-diastolic diameter(LVEDd), interventricular septum diameter(IVST), left ven-tricular posterior diameter(LVPWT), left ventricular myocardial mass(LVM)and left ventricular myocardial mass index(LVMI), left ventricular ejection fraction(LVEF), left ventricular fractional shortening(FS), cardiac output(CO) and serum N-terminal pro-brain natriuretic peptide(NT-pro BNP) level. We compared the changes and differences of the above indexes between the two groups before and after the treatment. Results 1.After 1 year of treatment, LVEDd, IVST, LVWT, LVM and LVMI were obviously improved both in the control group and treatment group. There were significant differences before and after the treatment(P <0.05).After the treatment, They were better improved in the treatment group than in the control group with significant differences(P <0.05). 2. After 1 year of treatment, EF, CO, FS and pro-NTBNP were obviously improved both in the control group and treatment group. There were significant differences before and after the treatment(P <0.05).After the 1 treatment, They were better improved in the treatment group than in the control group with significant differences(P <0.05).Conclusions For parients with CHF combined with BPH taking finasteride may improve cardiac function and left ventricular remodeling.
