title: Long-term functional results of surgery for coronary artery disease in patients with poor ventricular function.
abstract: Thirty-two patients with coronary artery disease and an ejection fraction (EF) below 0.40 had coronary bypass and/or left ventricular aneurysm (LVA) resection. Twenty-four patients had a previous infarction, 12 had congestive heart failure (CHF), and left ventricular end-diastolic pressure averaged 15 mm. Hg. Nineteen patients had three-vessel involvement and there was an  average of 2.4 vessels involved per patient. Bypass was accomplished on 87 per cent of vessels; 11 patients had resection of LVA; 11 had coronary endarterectomy. There were no hospital deaths, 63 per cent of the patients were improved, and 56 per cent were able to return to work or full activity. There were five late deaths (16 per cent). There was good functional improvement in 83 per cent of the survivors, followed 1 to 4 years. We believe that patients with poor ventricular function due to severe coronary artery disease should not categorically be denied surgery, and that operation can be done with a low hospital mortality rate and good functional results.
