An intraaortic balloon pump was placed. Left ventricular pressures were 105/28 prior to insertion of this device. An echocardiogram was performed that showed a large hypokinetic segment involving the anterior, anteroseptal, and apical portions of the left ventricle with an estimated ejection fraction of 15%. There was no evidence for a pericardial effusion or tamponade. A repeat echocardiogram was performed the following day, and the findings were unchanged. The patient remained hemodynamically stable and was started on therapy with aspirin, clopidogrel, atorvastatin, metoprolol tartrate, and ramipril. Treatment with the intraaortic balloon pump was discontinued after 3 days.
