摘　　要：目的:评价丙胺苯丙酮合用硝酸异山梨酯对冠心病无症状心肌缺血(Silentmyocardialischemia,SMI)伴室性期前收缩(Prematureventricularcontraction,PVC)的治疗效果。方法:将97例冠心病SMI伴PVC患者随机分为3组,其中A组32例口服丙胺苯丙酮与硝酸异山梨酯;B组33例口服硝酸异山梨酯加安慰剂;C组32例口服丙胺苯丙酮加安慰剂。前者作为治疗组,后两者作为对照组。评价内容含血压、心率、二重乘积、PVC改善情况及心电图ST段压低次数,ST段压低持续总时间,心肌缺血总负荷等。结果:97例中全部完成疗程。3组用药后上述观察指标差异均有不同程度改善,其中以治疗组最明显。治疗组与两对照组比较,心率、二重乘积、PVC差异均有统计学意义(P<0.01),且治疗组用药前后自身比较,上述指标也有统计学意义(P<0.01),SMI的发作次数及其持续总时间显著减少(P<0.01),心肌缺血总负荷也显著降低(P<0.01)。治疗组和对照组比较,血压影响差异无统计意义(P>0.05),未见明显不良反应。结论:丙胺苯丙酮与硝酸异山梨酯治疗SMI伴PVC有效。Objective:To evaluate the curative effect of propylamine benzene acetone plus isosorbid dinitrate on silent myocardial ischemia(SMI)combined with premature ventricular contraction(PVC).Methods:97 cases of SMI combined with PVC were divided into 3 groups.Group A (treated group,)was given orally SMI plus PVC.Guoup B and group C control group I and II)took by mouth isosorbid dinitrate plus placebo and propylamine benzene acetone plus placebo,respectively.After that the blood pressure,heart rate,product of HR×SBP×10^(-2),diveloped degree of PVC,the drop times of ST section in electrocariogram,the duration of drop of ST section and total load of myocardial ischemia were evaluoted.Results: After medication the aforementioned indices were improved in varying degrees in three group especially in group A The difference in heart rate,product of HR×SBP×10^(-2) and PVC between group A and groups B,C were of statistical significance (P<0.01).In group A there was a remarkeble difference before and after medication (P<0.01)in the indices described above.The time of SMI atteck and its duration decreased obviously (P<0.01),and the total load of myocardial ischemia was markedly bronght down(P<0.01).There was little difference in influence of blood pressure between treated group and two control groups(P>0.05),and the patients in these groups did not show any untoward reactions.Conclusion:Propylamine benzene acetone plus isosorbid dinitrate can be used to treat effectively SMI combined with PVC.
