Overview
- Emergency responders treated Graham for cardiac arrest at his Washington, D.C., home and he was taken to George Washington University Hospital where he was pronounced dead after a brief, sudden illness.
- The District of Columbia chief medical examiner completed an autopsy and released preliminary findings that the senator died from an aortic dissection caused by arteriosclerotic cardiovascular disease, with the death certificate to be updated after pending toxicology and microscopic testing.
- An aortic dissection is a tear in the inner layer of the aorta that lets blood split the vessel wall, a condition that often mimics heart attack or stroke and can require immediate surgery to survive.
- Doctors say the condition most often affects men in their 60s and 70s and is driven by long‑term artery damage and high blood pressure, so rapid diagnosis with CT angiography and tight blood‑pressure control are critical.
- Coverage notes political and public effects from the senator’s sudden death, including immediate tributes, questions about South Carolina’s replacement process, and renewed calls for family screening and blood‑pressure management to prevent similar deaths.
