Senator Lindsey Graham's sudden death has brought attention to a life-threatening cardiovascular emergency known as an aortic dissection. A statement from Graham's office revealed that preliminary findings from the District of Columbia's Office of the Chief Medical Examiner identified the cause of death as an aortic dissection due to arteriosclerotic cardiovascular disease.
Graham, 71, was transported to George Washington University Hospital, where he was pronounced dead at 10:23 p.m. on Saturday. An autopsy was completed on Sunday. The death certificate will be updated once all toxicological and microscopic testing are finalized.
An aortic dissection occurs when a tear develops in the inner layer of the aorta, the body's largest artery. Blood rushes through the tear, causing the layers of the aortic wall to separate, which can disrupt blood flow to vital organs or lead to a fatal rupture if not treated immediately.
Medical experts describe the condition as a tear in the wall of the aorta, which can progress rapidly due to elevated blood pressure. The aorta can be thought of as a hose with multiple layers, and when the layers separate, blood flow is disrupted.
Aortic dissection is a relatively rare condition, affecting an estimated three to four people per 100,000 each year. In Graham's case, the preliminary findings cited arteriosclerotic cardiovascular disease, which is associated with atherosclerosis, a buildup of plaque inside the arteries.
Arteriosclerotic cardiovascular disease can develop over time and is driven by several factors, including high blood pressure, high cholesterol, and smoking. Certain groups are at higher risk, including those with a family history of aortic disease or inherited connective tissue disorders.
Symptoms of an aortic dissection can come on suddenly and often mimic those of a heart attack or stroke. Warning signs include severe chest pain, elevated blood pressure, and a tearing sensation in the chest. Anyone experiencing these symptoms should seek immediate emergency medical care.
Early diagnosis and treatment greatly improve the chances of survival for those who have suffered an aortic dissection. Doctors typically diagnose the condition using imaging tests, including CT scans and MRI-based scans.
The mortality rate for aortic dissection is high, with approximately 1% to 2% of patients dying every hour treatment is delayed after symptoms begin. Without treatment, more than half of people with a Type A aortic dissection die within one month.
While not all aortic dissections can be prevented, people can reduce their risk by controlling certain lifestyle factors, such as maintaining healthy blood pressure, cholesterol levels, and weight. Quitting smoking and following treatment plans for underlying heart or vascular conditions can also reduce the risk.
Individuals with a family history of aortic disease or inherited connective tissue disorders should discuss screening with their healthcare provider. Regular check-ups and monitoring can help identify potential issues before they become life-threatening.
