What is an aortic dissection? The medical emergency revealed as Lindsey Graham’s cause of death

Sen. Lindsey Graham's unexpected death was attributed to an aortic dissection, a severe medical emergency where the inner layer of the aorta tears, leading to life-threatening internal bleeding. This condition, often occurring in individuals with pre-existing heart issues like arteriosclerotic cardiovascular disease, underscores the critical importance of cardiovascular health. Graham's passing highlights the often-overlooked but serious risks associated with these underlying conditions and the need for greater awareness and preventive care.
