[Clinical effect of China-made amrinone in the treatment of refractory congestive heart failure].

Clinical and hemodynamic studies were carried out in 20 patients suffering from refractory congestive heart failure with invasive technique and non-invasive methods such as tolerance exercise test, 24-hour Holter monitoring, etc. Digitalis was then withdrawn and China-made amrinone (AMR) was administered orally for 15 days. All the indices mentioned above were repeated and each patient served as his own control. The results indicate that AMR can improve hemodynamic parameters as well as exercise tolerance. Holter monitoring revealed no significant increase in arrythmogenic potentiality. The total clinical effective rate was 95%. No severe side effects were found except thrombocytopenia observed in 20% of the patients. It is suggested that China-made AMR is effective in treating refractory congestive heart failure.
