A thoracic aortic aneurysm is often asymptomatic, but when it does present with symptoms, these can include substernal pain, cough, and hoarseness. Each of these symptoms can occur due to the pressure exerted by the aneurysm on adjacent structures.

Substernal pain is a common symptom because the aneurysm can irritate the surrounding tissue or press against the chest wall, leading to discomfort or pain that may be felt in the substernal area.

Cough can occur if the aneurysm compresses the trachea or bronchi, leading to respiratory symptoms as the airway is mechanically affected. This kind of cough is often vague and may not be associated with an infectious illness.

While chest tightness is a subjective experience that could be related to various cardiovascular pathologies, it is not a classic symptom associated specifically with thoracic aortic aneurysm. The other symptoms have more direct anatomical relationships to the aneurysm, making chest tightness the least specific and not typically recognized as a defining symptom of thor
