What is aortic dissection? Lindsey Graham's death highlights silent threat, doctors warn

Intro / Summary
It's the kind of diagnosis many people have likely never heard of until tragedy brings it in focus. Doctors say Senator Lindsey Graham's death is a reminder that protecting your heart starts long before an emergency. “Dissection happens when the inner lining of the artery kind of peels into the lumen of the artery," Piedmont Medical Network Vascular Surgeon Dr. Christopher Everett said. "I describe it like wallpaper peeling into a room. Risk factors for that are patients in their 60s, men and high blood pressure."
