Prevalence of atypical chest pain descriptions in a population from the southern United States.
BACKGROUND
The character of chest pain (CP) is a major factor determining triage and admission for patients presenting to the emergency department (ED). Previous studies have found atypical descriptions in as little as 10-15% of patients with true myocardial ischemic pain. Atypical descriptions may be more prevalent in the Deep South of the United States because of cultural differences in the semantic description of pain.


METHODS
A retrospective study of patients presenting to the ED of a southern U.S. urban hospital with enzyme-documented myocardial infarction was conducted to determine the prevalence of atypical CP descriptions. A multivariate analysis of those patients with atypical pain descriptions was conducted to determine the independent demographic factors associated with these descriptions.


RESULTS
In a total of 77 subjects (56% black; 44% white) meeting the study criteria, 43% were found to have atypical elements in the character of their CP descriptions. Only the black race demographic was found to be significantly correlated with the atypical descriptions. The use of the descriptive term "sharp" accounted for nearly half of the atypical presentations.


CONCLUSIONS
Regional differences in the description of the character of CP may result in misleading portrayals of ischemic heart disease in southern U.S. populations. These differences are associated with a higher prevalence of atypical CP because of semantic distinctions, such as the use of the term "sharp" as a descriptor of acuity rather than character or quality.
