What is it about?

An aortic aneurysm is an abnormal bulge that occurs in the wall of a major blood vessel (aorta). Currently, little is known about the underlying risk factors of disease progression. In this cohort study, we identified sleep apnea (i.e. pauses in breathing during sleep) as a risk factor for faster aneurysm expansion.

Why is it important?

Sleep apnea is one of the most common sleep disorders. Untreated sleep apnea might contribute to life-threatening complications in aortic disease. However, if correctly diagnosed, it can be easily treated.


I have started my research career with this cohort in June 2014 and it was the beginning of a great adventure. Writing this article was a great pleasure as it has co-authors with whom I have developed long standing collaborations.
