Derivatin and Validation of a Risk Prediction Score for Late Aortic Events in Uncomplicated Stanford Type B Aortic Dissectio
Not Applicable
- Conditions
- ncomplicated acute type B aortic dissection
- Registration Number
- JPRN-UMIN000030561
- Lead Sponsor
- Department of Global Clinical Research, Graduate school of Medicine, Chiba University
- Brief Summary
The risk prediction score system was developed using the following independent predictors: initial aortic diameter of >= 40 mm (2 points), false lumen diameter > true lumen diameter (2 points), ulcer-like projection (1 point), and age of >= 70 years (1 point). ROC analysis showed that a cut-off total additive score of 2 points. In the validation cohort, the low-risk group (score of 0-1 points) demonstrated lower 1- and 3-year incidence rates of late aortic events than the high-risk group.
