Chest Pain Evaluation in the Emergency Department: Can MDCT Provide a Comprehensive Evaluation?
Charles S. White, Dick Kuo, Mark Kelemen, Vineet Jain, Amy Musk, Eram Zaidi, Katrina Read, Clint Sliker and Rajnish Prasad
Patients with chest pain who presented to the emergency department without definitive findings of acute myocardial infarction based on history, physical examination, and ECG were recruited immediately after the initial clinical assessment. For each patient, the emergency department physician was asked whether a CT scan would normally have been ordered on clinical grounds (e.g., to exclude pulmonary embolism). Each consenting patient underwent enhanced ECG-gated 16-MDCT. Ten cardiac phases were reconstructed. The images were evaluated for cardiac (coronary calcium and stenosis, ejection fraction, and wall motion and perfusion) and significant noncardiac (pulmonary embolism, dissection, pneumonia, and so forth) causes of chest pain. Correlation was made between the presence of significant cardiac and noncardiac findings on CT and the final clinical diagnosis based on history, examination, and any subsequent cardiac workup at the 1-month follow-up by a consensus of three physicians.
Sensitivity and specificity for the establishment of a cardiac cause of chest pain were 83% and 96%, respectively. Overall sensitivity and specificity for all other cardiac and noncardiac causes were 87% and 96%, respectively.
ECG-gated MDCT appears to be logistically feasible and shows promise as a comprehensive method for evaluating cardiac and noncardiac chest pain in stable emergency department patients. Further hardware and software improvements will be necessary for adoption of this paradigm in clinical practice.
