Key result
Newer evaluation techniques, including ECG modifications, myocardial markers, and acute rest myocardial perfusion imaging, improve diagnostic sensitivity and risk stratification for ED chest pain patients.
The use of newer cardiac biomarkers and myocardial perfusion imaging improves the diagnostic accuracy and risk stratification of patients presenting to the ED with chest pain.
May refine ED chest pain triage; hypothesis-generating pending prospective outcome trials.
Patients presenting to the Emergency Department with chest pain are common and often present diagnostic difficulties. Because of the limitations of the initial evaluation, the majority of patients are admitted, although many are later found to have noncardiac causes for their symptoms. Recognition of these limitations has driven the investigation of newer evaluation techniques and protocols in an attempt to improve diagnostic sensitivity without increasing overall costs. These have included modifications of the standard ECG, and use of newer myocardial markers such as mass assays for CK-MB and troponin T and I. Use of acute rest myocardial perfusion imaging has also been shown to be a highly valuable technique for risk stratification of the intermediate- to low-risk chest pain patient.

Michael Kontos (2001) conducted a review in Chest pain in the Emergency Department. Newer evaluation techniques (ECG modifications, myocardial markers, acute rest myocardial perfusion imaging) was evaluated. Newer evaluation techniques, including ECG modifications, myocardial markers, and acute rest myocardial perfusion imaging, improve diagnostic sensitivity and risk stratification for ED chest pain patients.
