静注国产氨吡酮治疗心衰

Intravenous efficacy of home made amrinone in the treatment of heart failure

随机、双盲法观察结果表明:在首剂静注国产氨吡酮1 mg/kg,并每天以7.5μg·kg^(-(?))/min 静滴6h 连续1周后,71.9%的心衰患者心功能改善,超声多普勒心指数由3.36±0.87增至3.88±1.03 L·min^(-1)/m^2.8例血液动力学检查示心指数上升23.8%,且与血药浓度相关,肺楔嵌压降低37.5%.氨吡酮和对照组室性早搏发生率分别为18.8%和9.1%.

Sixty five cases of heart failure were observed with double blind method.The patients randomised to amrinone group re- ceived a loading dose of 1mg/kg followed by a continuous infusion of 7.5 μg·kg^(-1)/min for six hours,this infusion dose was given once a day for seven day period.Heart function in amrinone group was improved in 71.9%(23/32)cases compared to 36.4%(12/33)in plocebo group;car- diac index in Doppler echocardiograph changed from 3.36±0.87 to 3.88 ±1.03(L.min^(-1)/m^2)(P<0.05)and 3.29±0.17 to 3.24±1.02(L.min^(-1)/ m^2)(P>0.05)respectively.Hemodynamic changes of 8 cases in the first six hours showed that the maxium increasement of cardiac index was 23.8%,the correlation was significant between cardiac index and serum drug concentration(r=0.64,P<0.05).The agent lowered sys- temic resistance by 34.8%,pulmonary vascular resistance by 37.1%,pul- monary capillary wedge pressure by 37.5%.Six cases(6/32,18.8%) had premature ventricular beats in amrinone group,but 3(3/33,9.1%) in placebo.It is concluded that intravenous anarinone of home made can be used in the treatment of heart failure.
