Hand-held echocardiogram does not aid in triaging chest pain patients from the emergency department.
BACKGROUND
Accurate triage of emergency department (ED) patients presenting with chest pain is a primary goal of the ED physician. In addition to standard clinical history and examination, a hand-held echocardiogram (HHE) may aid the emergency physician in making correct decisions. We tested the hypothesis that an HHE performed and interpreted by a cardiology fellow could help risk-stratify patients presenting to the ED with chest pain.


METHODS
ED physicians evaluated 36 patients presenting with cardiovascular symptoms. Patients were then dispositioned to either an intensive care bed, a monitored bed, an unmonitored bed, or home. Following disposition, an HHE was performed and interpreted by a cardiology fellow to evaluate for cardiac function and pathology. The outcomes evaluated (1) a change in the level of care and (2) additional testing ordered as a result of the HHE.


RESULTS
The HHE showed wall motion abnormalities in 31% (11 out of 36) of the studies, but the level of care did not change after HHE for any patients who presented with chest pain to the ED. No additional laboratory or imaging tests were ordered for any patients based on the results of the HHE. Eighty-six percent (31 out of 36) of the studies were of adequate quality for interpretation, and 32 out of 36 (89%) interpretations correlated with an attending overread.


CONCLUSIONS
Despite the high prevalence of abnormal wall motion in this population, hand-held echocardiography performed in this ED setting did not aid in the risk stratification process of chest pain patients.
