A successful treatment with long-term intra-aortic balloon pumping (IABP) in a patient with cardiogenic shock due to recurrent acute myocardial infarction was described.A 69-year-old male developed an acute myocardial infarction (AMI) of the left ventricular inferior wall and of the right ventricle with a peak CPK level of 2155 IU/1. After 10 days of conventional treatment, AMI of inferior wall of the left ventricle recurred with a peak CPK level of 460 IU/1 and followed by a cardiogenic shock. A balloon catheter with a volume of 30ml was introduced percutaneously via femoral artery. But the improvement of the patient's hemodynamic state was gradual and minimal, so IABP was continued for several days. The patient gradually took a better course, so we tried to wean him from it but failed at the early stage of weaning because of a fall in systemic arterial pressure. Meanwhile, a partial weaning was begun on the 10th day after the initiation of balloon support and completed on the 14th day. The patient was discharged about 4 months after his admission.A prompt initiation of IABP in the early stage of cardiogenic shock is recommended in combination with surgical intervention, if necessary.
