Key result
Common carotid stiffness index (β) was an independent predictor for the occurrence of acute aortic dissection in hypertensive patients (OR 2.140; 95% CI 1.931-2.367; P<0.001).
Why the study?
To evaluate common carotid stiffness via echo tracking in hypertensive patients with acute aortic dissection and identify independent predictors of aortic dissection in hypertensive patients.
Do common carotid stiffness parameters measured via echo tracking predict the occurrence of acute aortic dissection in hypertensive patients?
Population
50 hypertensive patients with acute AD, 50 hypertensive patients without AD, and 50 healthy volunteers
Comparison
Hypertensive patients with acute AD vs hypertensive patients without AD vs healthy volunteers

May aid aortic dissection risk stratification in hypertension; hypothesis-generating pending prospective validation.

Do common carotid stiffness parameters measured via echo tracking predict the occurrence of acute aortic dissection in hypertensive patients?
Odds Ratio: 2.14 (95% CI 1.931–2.367)
p-value: p=<.001
Common carotid stiffness parameters measured by echo tracking, combined with systolic blood pressure, are strong independent predictors of acute aortic dissection in hypertensive patients.
Gu et al. (2020) conducted a case-control in Hypertension and acute aortic dissection (n=150). Common carotid stiffness (stiffness index β) vs. Hypertensive patients without aortic dissection and healthy volunteers was evaluated on Occurrence of acute aortic dissection in hypertensive patients (OR 2.140, 95% CI 1.931-2.367, p=<.001). Common carotid stiffness index (β) was an independent predictor for the occurrence of acute aortic dissection in hypertensive patients (OR 2.140; 95% CI 1.931-2.367; P<0.001).
