Diagnosing acute aortic syndromes: the role of specific biochemical markers.
Acute aortic syndromes (AAS) remain one of the most challenging medical emergencies. Making a prompt and accurate diagnosis is a race against time, where delay may be disastrous for the patient's life. Prompt and accurate diagnosis using imaging modalities has been available for many years, but the major concern is how the clinician's suspicion should be aroused concerning the possibility of an acute aortic syndrome, especially in cases of atypical clinical presentation and/or poor signs during clinical examination. Since the first case report publication in 1995, novel biochemical markers have been used for the rapid diagnosis of AAS, such as smooth muscle myosin heavy chains, serum soluble elastin fragments, and d-dimers, with the latter being the most widely used in clinical trials. Despite their potential, all these substances need to be re-evaluated in large randomized trials before they can be included as biomarkers of high sensitivity and specificity in clinical practice.
