I have some questions about chest pains that I have occasionally. I am 27, 5'11. 130lbs. I have some features of Marfans, but ekgs, echocardiogram, and chest xrays show nothing wrong with my heart. I have occasional chest pains. MY question is, do chest x-rays and echocradiogram give a full picture of the aorta? Since they were normal, can I rest easy? Are these just angina or anxiety pains? How far up in the chest cavity does the aorta go?
