Widening of the ascending aorta in the elderly may be normal, such as may occur with increasing age; it may also be abnormal, such as due to congenital factors or cardiovascular disease. 1. Normal: Widening of the ascending aorta is related to age. As age increases, especially in the elderly, the elasticity of the arteries gradually decreases, and widening of the ascending aorta may also occur, which is a normal physiological phenomenon. 2. Abnormal: (1) Congenital factors: for example, equine syndrome, a hereditary connective tissue disease, characterized by long, thin and disproportionate limbs, fingers and toes, with height significantly exceeding that of normal people, accompanied by abnormalities of the cardiovascular system, especially combined heart valve abnormalities and aortic aneurysms. The development of the blood vessel wall in patients with equine syndrome is relatively weak, and therefore it is easier to dilate, resulting in widening of the ascending aorta. (2) Cardiovascular diseases: For example, in patients with hypertension combined with aortic sclerosis, the elasticity of blood vessels will decrease due to arteriosclerosis, and then the ascending aorta will widen after the blood pressure rises. If the elderly have abnormal widening of the ascending aorta, accompanied by physical discomfort, it is necessary to immediately consult a doctor to identify the cause and follow the doctor’s instructions for treatment.
