Aortic dissection has a way of cutting through headlines because it is sudden, brutal, and easy to miss until it is already an emergency. With Lindsey Graham’s reported death drawing fresh attention to the condition, the people behind this story are pushing a familiar warning: know the signs, know the risks, and do not shrug off chest or back pain that feels off.
According to preliminary findings cited by Graham’s office, the cause of death was an aortic dissection tied to arteriosclerotic cardiovascular disease. In plain terms, that means the wall of the aorta, the body’s biggest artery, split apart after a tear formed in the inner layer. Doctors say the condition can move fast, and that speed is exactly what makes it so dangerous.
“It occurs when the layers of the aorta (the body’s largest artery) come apart and the inner one tears,” Fox News senior medical analyst Dr. Marc Siegel, who did not treat Graham, told Fox News Digital. He added that it can appear in minutes or stretch out over days, but the warning signs can still be easy to miss when someone is not expecting something this serious. That unpredictability is part of why the condition has a reputation for hitting hard and fast.
Graham is not the only well-known figure linked to this diagnosis. John Ritter, the beloved actor from “Three’s Company,” died from an aortic dissection in 2003, and his case helped drive more public awareness around the condition. The John Ritter Foundation for Aortic Health later said Graham’s death brought “needed attention” to a problem that can be deadly if it is not spotted in time.
Ritter was taken to the hospital after symptoms that were later identified as a type A aortic dissection, which involves the upper part of the aorta near the heart. That type is especially urgent because it often needs emergency surgery right away. He had been filming “8 Simple Rules… for Dating My Teenage Daughter” at the time, and what started as a medical scare quickly turned into a tragedy.
The foundation has kept hammering home one message: these deaths are not always inevitable. “Deaths due to aortic dissections are preventable if individuals at risk are identified and properly treated.” That line lands hard because it points to the real issue, which is not just recognizing symptoms after the fact, but catching the people most likely to be in danger before disaster strikes.
Rep. Doug LaMalfa, R-Calif., was also reported to have died from complications of an aortic dissection in January 2026. He reportedly went into emergency surgery but did not make it through the procedure, and cardiomegaly, or an enlarged heart, was listed as another significant condition. His death reinforced how quickly this can go from a medical crisis to a fatal one.
Alan Thicke, known for “Growing Pains,” died in 2016 after experiencing chest pain while playing hockey with his son. The Los Angeles County coroner later determined that he died from a ruptured aorta caused by a type A aortic dissection. His case is another reminder that people can mistake the early symptoms for something less serious, even when the body is signaling a true emergency.
Doctors say chest pain is one of the biggest red flags, especially when it shows up suddenly and feels severe. “The pain associated with an aortic dissection is extreme,” one surgeon said, describing it as the kind of pain that can drop people to their knees. That kind of description is grim, but it is also useful, because vague discomfort and a true dissection are not in the same league.
Risk factors matter too, and they are not exactly a mystery. Age, high blood pressure, enlarged blood vessels, and damage to the vessel wall from cardiovascular disease can all raise the odds, while a weakened aorta becomes more vulnerable over time. Once the tear starts, blood pressure can force it to spread, and the situation can become a race against the clock.
That is why type A dissections are treated as immediately life-threatening, while type B dissections, which are farther from the heart, may not always require instant surgery. Even so, both can be serious, and both demand real attention instead of wishful thinking. For anyone with a history of high blood pressure or other heart issues, doctors keep coming back to the same advice: pay attention, get checked, and take symptoms seriously when they show up.
