Could the combination of fibrinogen and D-dimer improve risk assessment for acute type A aortic dissection in the emergency department?
D-dimer has been proven to be an excellent rule-out marker for acute type A aortic dissection (ATAAD) with a sensitivity exceeding 95% while specificity remains low. We hypothesized that the addition of fibrinogen, which is decreased in ATAAD patients due to consumption coagulopathy, would increase predictive ability. This was an exploratory, retrospective, single-region, observational study compa
