Objective To evaluate effection of Milrinone in patients with pneumocardial disease at acute exacerbation stage .Methods Eighty-three patients were randomly divided into two groups , both in the same conventional therapy , the treatment group received 10mg of Milrinone dissolve in 250ml 5% glu-cose intravenous infusion , 1 second /day, 10 days for a course of treatment .Observation group were treated with 5%glucose infusion 250ml, 1 time /day.The arterial blood gas, echocardiography measurements with mean pulmonary artery pressure , left ventricular ejection fraction and clinical evaluation to improve cardiop-ulmonary function efficiently were compared before and after treatment .Results Arterial blood gas analy-sis, pulmonary artery pressure and left ventricular function were improved and comprehensive evaluation of the efficiency of cardiopulmonary function in treatment group were significantly better than the control group ( Pall<0.05).Conclusion There is satisfactory of Milrinone in acute exacerbation of chronic pulmonary heart disease .
