STAT+: University of Michigan wins 2026 STAT Madness for new insights into abdominal aortic aneurysms

An abdominal aortic aneurysm is a life-threatening vascular condition with limited treatment options. 

Now, researchers from the University of Michigan Frankel Cardiovascular Center have identified a driving force behind the condition, opening up a potential target for new therapies. Their paper uncovering the causal link between triglycerides and abdominal aortic aneurysms won the STAT Madness 2026 popular vote. 

Triglycerides have long been considered a biomarker for vascular disease. But using three different mouse models, the Michigan team demonstrated that the common type of fat plays a direct role in aneurysm development, and that lowering triglyceride levels with certain drugs can stop them from forming and rupturing.
