2-D speckle tracking echocardiography

Jae K. Oh, M.D., leads this study to improve the diagnosis of acute coronary syndrome (ACS) in individuals with chest pain who visit the emergency department.

Acute coronary syndrome is the leading cause of death in the U.S. and Europe, and is associated with more than 2.5 million hospitalizations worldwide each year. It is estimated that a myocardial infarction occurs every 34 seconds in the U.S. and that one person dies each minute from a major coronary event. Patients with ACS typically present acute chest pain, but in patients with few objective findings, abnormalities could be detected by 2-D speckle tracking echocardiography. The 2-D speckle tracking echocardiography is reported to be useful for the diagnosis of myocardial ischemia because it can be used to detect small changes in the heart, such as delay in myocardial expansion after an episode of angina; these changes can persist for up to 24 hours after the relief of ischemia.

The investigators plan to evaluate the feasibility and validity of testing 2-D speckle tracking echocardiography in the triage of patients with ACS who visit emergency departments complaining of chest pain.
