Aortic dissection is a critical medical condition that can lead to sudden death. The aorta, the body’s largest artery, carries oxygen-rich blood from the heart to the rest of the body. A dissection occurs when a tear in the aorta’s inner layer allows blood to seep between its layers. This causes reduced blood flow to vital organs and could result in a rupture, spilling blood into surrounding tissues.
An aortic dissection frequently stems from an aortic aneurysm, which is a weakened area that bulges out like a balloon. Risk factors include high blood pressure, high cholesterol, known as atherosclerosis, and smoking. Though it is more common in older adults, certain genetic conditions can impact younger individuals.
The preliminary report from Sen. Lindsey Graham’s office indicated his death was due to an aortic dissection related to hardened arteries. Symptoms of this condition are often sudden and severe. They can include intense, stabbing pain in the chest or back, and potentially in the neck, jaw, or abdomen depending on the tear’s location.
Other symptoms identified by the heart association may involve sudden loss of consciousness, sweaty or clammy skin, stroke-like symptoms such as weakness on one side of the body, and signs of shock, such as rapid heart rate or confusion. Immediate medical attention is crucial. Surgeons may repair or patch the torn aorta, depending on the position and severity of the tear.
