Echocardiography in the Emergency Room Acute chest pain is one of the most common reasons for presentation to the Emergency Department (ED) accounting for approximately 7 million ED visits per year in the United States. The challenge for the clinician is to identify those patients with a serious cause of chest pain requiring intervention, particularly when acute coronary syndromes (ACSs) present with atypical symtoms, or diagnostic changes in the electrocardiogram(ecg) or cardiac enzyme markers are lacking.
Echocardiography in the Emergency Room Time is also of the essence when it comes to a patient with chest pain. Early treatment of myocardial injury and other serious diagnoses improves morbidity and mortality.
Echocardiography in the Emergency Room The diagnosis of myocardial infarction (MI) is generally based on patient history electrocardiographic findings and cardiac enzyme levels. Unfortunately these markers often take hours from symptoms onset to exceed the normal range and are note elevated in ACSs that are not associated with frank myocardial necrosis.
Echocardiography remains a first-line test and continues to provide valuable information on left ventricular and valvular function.
Echocardiography in the Emergency Room Depending on the particular cardiac marker, enzyme levels can also be elevated in the absence of ACS, depending on renal function and underlying disease process. Electrocardiographic changes are frequently nonspecific Given these limitations, echocardiography can be a useful adjunct in assessing the patient with chest pain

ECHOCARDIOGRAPHY TTE provides a rapid bedside assessment of wall motion and global left ventricular function and it excludes the presents of major complications. In the patient with an established myocardial infarction early evaluation of LV ejection fraction, diastolic function, regional wall motion and mitral regurgitation greatly assist with management.

Conclusions Echocardiography provides key diagnostic and prognostic information All mechanical complications of AMI can be detectable by echocardiography Newer echocardiographic techniques allow a comprehensive assessment of global and regional LV function, myocardial perfusion, myocardial viability and can predict functional recovery after MI.
