Key result
The combined use of an ADD risk score ≥1 and an ascending aorta diameter >40 mm was highly indicative of A-AAD, with 84.6% sensitivity, 87.6% specificity, 76.7% PPV, and 92.2% NPV.
Why the study?
Does the combined use of the ADD risk score and ascending aorta diameter >40 mm improve the early identification of type A acute aortic dissection in patients with acute chest pain?
Observational (n=239)
No
Does the combined use of the ADD risk score and ascending aorta diameter >40 mm improve the early identification of type A acute aortic dissection in patients with acute chest pain?
Combining an ADD risk score ≥1 with an ascending aorta diameter >40 mm on TTE provides high diagnostic accuracy for the early identification of type A acute aortic dissection in patients presenting with acute chest pain.

May aid early A-AAD detection in chest pain; extends ADD score data but leaves open prospective validation.
Wang et al. (2018) conducted an observational in Acute chest pain / Type A acute aortic dissection (n=239). Aortic dissection detection (ADD) risk score combined with ascending aorta diameter >40 mm vs. ADD risk score alone was evaluated on Diagnosis of type A acute aortic dissection (A-AAD). The combined use of an ADD risk score ≥1 and an ascending aorta diameter >40 mm was highly indicative of A-AAD, with 84.6% sensitivity, 87.6% specificity, 76.7% PPV, and 92.2% NPV.
