title: Outcome analysis of chest pain patients discharged from the ED--a pilot study.
abstract: The objective of this pilot study was to determine clinical predictors of adverse outcome, defined as myocardial infarction, angioplasy or stent placement, coronary artery bypass graft, or death, within 60 days for patients discharged from the emergency department with a presenting complaint of chest pain. All patients presenting to the emergency department with a chief complaint of chest pain were eligible for the study. A chest pain risk analysis sheet was completed as part of the patient evaluation. Patients discharged from the emergency department, in whom a risk analysis sheet was completed, were contacted to determine their clinical course within 60 days of their discharge from the emergency department. During the 6-month study period, 129 eligible patients were enrolled. Of these 129 patients, four had an adverse outcome within 60 days of their discharge. All four patients had either a balloon angioplasty procedure, coronary artery bypass graft, or both. None of the study patients had a myocardial infarction or died. Statistically significant predictors of adverse outcome in our study population were an abnormal electrocardiogram (ECG), a history of myocardial infarction, and a history of hypertension. In conclusion, patients discharged from the emergency department with a presenting complaint of chest pain were at a low risk for having a myocardial infarction or dying within 60 days of their discharge. Several patients, however, did have significant coronary artery disease requiring angioplasty or bypass. These patients were more likely to have an abnormal ECG, a history of myocardial infarction, or have a history of hypertension. A prospective study with larger numbers of patients is needed to validate these findings.
