The sudden death of Sen. Lindsey Graham on July 11, 2026, at age 71 brought an unfamiliar medical term into the headlines: aortic dissection. Writing for TIME, Veronique Greenwood explains the condition in plain terms, while physician and epidemiologist Dr. Céline Gounder offers a personal perspective in a CBS News essay after losing her husband to aortic disease. Together, they explain a condition that often remains silent until it becomes a medical emergency.

Key Highlights

• What happens during an aortic dissection. Greenwood explains that an aortic dissection occurs when the inner lining of the aorta, the body’s largest artery, tears. Blood then flows between the artery’s layers, forcing them apart. Gounder distinguishes three related conditions: an aneurysm is a bulge that develops over time, a dissection is a sudden tear, and a rupture is when the artery bursts, often with fatal results. As she writes, “Bulge, tear, burst. One can set off another, but they aren’t the same.”
• Symptoms to watch for. According to Greenwood, the classic symptom is sudden chest pain that may spread to the back or neck. Cardiac surgeon Dr. Graham Cooper says the pain can be severe, come and go, or fade after a short time. Other symptoms may resemble a heart attack or stroke, or appear as severe abdominal pain. Survivor Simon Jones sought care for persistent abdominal pain, and a CT scan ultimately revealed the dissection.
• Why it is so deadly. Greenwood reports that the most common type of aortic dissection is fatal in about half of patients, often within minutes. Cooper explains that the damaged aorta can rupture, allowing blood to collect around the heart and stop it from pumping. About 13,000 Americans die from aortic dissection each year.
• Two forms of aortic disease. Gounder emphasizes that not all aortic disease has the same cause. Graham’s dissection developed at age 71 after years of high blood pressure and hardened arteries, the more common age-related form. Her husband, soccer journalist Grant Wahl, died in 2022 at age 49 after an inherited aneurysm ruptured during the World Cup. His condition was later linked to a variant in the FBN1 gene associated with Marfan syndrome. The distinction matters because each form requires a different approach to prevention and treatment.
• How prevention differs. For the common form, Greenwood says prevention focuses on controlling blood pressure and quitting smoking. Gounder adds that emergency physicians should continue to consider aortic dissection because it is still mistaken for a heart attack. The only recommended screening test is a one-time ultrasound for men aged 65 to 75 who have ever smoked. For inherited forms, family history is key. If a close relative has had a thoracic aneurysm or dissection, or died suddenly before age 60, first-degree relatives may benefit from imaging and, in some cases, genetic testing.
• How one death can protect others. Gounder describes how her husband’s autopsy identified the genetic variant responsible for his condition, allowing relatives to be tested. His brother Eric carries the same variant and now receives regular imaging to detect changes before they become life-threatening. As Gounder writes, the autopsy “gave the people who share Grant’s DNA something they could act on.”

Greenwood and Gounder reach the same conclusion from different perspectives. Aortic dissection is often called a silent killer because it can strike people who seem perfectly healthy. Yet it is not always unavoidable. Recognizing the warning signs, controlling blood pressure, and knowing your family history can help identify risk earlier and improve the chances of timely treatment.
