Abstract In an effort to determine the usefulness of prodromata for predicting a myocardial infarction, a prospective analysis was made of 211 consecutive patients with chest pain who were admitted to the Stanford University Medical Center Coronary Care Unit. In their subsequent course, 91 patients had a myocardial infarction, 102 had a myocardial infarction ruled‐out, and 18 had a noncardiac etiology for their chest pain. Prodromal chest pain in the previous six months had occurred in 65% of patients and unstable angina in 61%. Infarction versus noninfarction patient groups could not be identified on the basis of prodromal ill health, chest pain, unstable angina, typical versus atypical nature of the chest pain, or activity at the onset of pain. Complaints of preceding fatigue and increased perceived stress were common in both groups. Activity at the onset of the admission chest pain was strenuous in 15% of the infarction patients and 12% of the noninfarction patients. We conclude that prodromal symptoms are common in both infarction and noninfarction patients. Although chest pain probably remains the single most frequent identifier of a new cardiac event, it is common in noninfarction patients and cannot be used alone to predict infarction or death.
