Key result
Chest radiographic signs did not accurately distinguish acute aortic dissection from acute myocardial infarction.
Why the study?

Population
18 patients with acute aortic dissection and 25 patients with acute myocardial infarction (total n=43)

Chest radiography lacks accuracy distinguishing acute aortic dissection from MI; hypothesis-generating for prospective imaging triage studies.
Observational (n=43)
Can chest radiography accurately discriminate between acute aortic dissection and acute myocardial infarction?
Chest radiography cannot reliably distinguish between aortic dissection and myocardial infarction, suggesting it should not delay thrombolysis in patients with clinical features of suspected MI.
Hartnell et al. (1993) conducted an observational in Acute aortic dissection and acute myocardial infarction (n=43). Chest radiography was evaluated on Accuracy of radiographic signs in distinguishing aortic dissection from myocardial infarction. Chest radiographic signs did not accurately distinguish acute aortic dissection from acute myocardial infarction.
