地奥心血康对冠心病左室功能不全的影响

Effects of Di-ao-xin-xue-kang on coronary heart disease with left ventricular dysfunction

冠心病４６例（男性３０例，女性１６例；年龄５７±ｓ１１ａ），口服地奥心血康２００ｍｇ，ｔｉｄ，治疗４－８ｗｋ。采用二维多普勒超声心动图测定左心室功能。治疗后每搏量（ＳＶ）、每分输出量（ＣＯ）及射血分数（ＥＦ）值均增加（Ｐ＜０．０１），舒张早期血流峰值速度（ＶＥ）舒张期最大充盈率（ＰＦＲ）均升高（Ｐ＜０．０１），同时心率、血压均下降（Ｐ＜０．０１）。不良反应轻微。＊Ｐ＜０．０１。４不良反应４例患者出现轻度胃肠道反应，经减量及对症治疗后症状缓解，未中断治疗。讨论本文治疗前４６例患者全部有左室舒张功能不全，１２例合并左室收缩功能不全，后者占２６％，与文献［３］认为左室舒张功能不全出现在收缩功能损害之前相符。本文用地奥心血康治疗４－８ｗｋ结果显示全部患者左室舒张功能及泵血功能均有改善。１０例心功能Ⅲ级者同时合并左室收缩功能异常，治疗２ｗｋ后停用地高辛及利尿剂，继续单用地奥心血康治疗６ｗｋ，收缩功能维持在正常低限，表明该药有改善泵血功能作用。我们还观察到停用地奥心血康后，患者心功能改善仍可维持４－６ｗｋ。患者心功能改善的机制，我们认为与下列因素有关：血压下降后使总外周阻力下降、减轻心脏收缩期负荷；心率减慢后使心肌氧耗?

Forty-six patients(M30,F16;age 57± s11 a) with coronary heart disease were treated with DI-ao-xin-xue-kang 200 mg po tid for 4-8 wk.Before and after treatment cardiac function were assessed by two-dimensional Doppler echocardiography.Results showed that the heart rate, systolic and diastolic blood pressure,mean artery pressure were all decreased (P< 0.01); left ventricular systolic function parameters(SV.CO and EF) were improved (P<0.01), left ventricular diastolic function parameters(peak velocity E.PFR and NPFR)were also improved (P<0.01) Adverse reactions were mild.
