STUDY OBJECTIVES: To describe the clinical and ECG features of cocaine abusers evaluated in the emergency department and admitted to the medical coronary care unit with chest pain consistent with myocardial ischemia. DESIGN: A four-month retrospective review of all cocaine abusers who presented to the ED with chest pain and a diagnosis of possible myocardial infarction. SETTING: Urban county hospital. TYPE OF PARTICIPANTS: Forty-eight adult cocaine abusers admitted with chest pain. MEASUREMENTS AND MAIN RESULTS: Patients included 34 men and 14 women with a mean age of 29 +/- 7.3 years. The average duration of cocaine abuse in 28 patients for whom it was reported was 5 +/- 4.8 years. Chest pain occurred within one hour of cocaine abuse in 13 admissions (27%), more than one hour after abuse in 13 admissions (27%), and it was not recorded in 23 admissions (47%). Initial ECGs were evaluated in all patients and revealed significant repolarization abnormalities consisting of abnormal ST segment elevations in 18 (37%) and T-wave inversions in 20 (41%) that often persisted on subsequent ECGs. Three patients sustained acute myocardial infarctions. CONCLUSIONS: Our findings confirm a small but significant incidence of myocardial infarction in cocaine abusers presenting to the ED with chest pain. The chronicity of cocaine abuse, the persistence of ECG abnormalities, and the variable temporal relationship of chest pain to cocaine abuse suggest possible chronic myocardial changes as etiologies of ischemia.
