An average 17.9-month follow-up was obtained on 169 patients with chest pain who were admitted to the Stanford University Hospital coronary care unit to rule out a myocardial infarction. Criteria for study included electrocardiographic ST-T abnormalities in the absence of infarction as evidenced by lack of new Q waves or serial enzyme determinations.
A high incidence of subsequent cardiac death following discharge from the coronary care unit was noted, with 4.2% one-month, 10.1% one-year, and 19.7% two-year mortality with 43% of the deaths occurring suddenly. More aggressive evaluation, treatment, and follow-up is indicated in this patient group.
