Dear sir. I m suffering from chest pain both right and left side. I done my 2D echo on july and it is normal and also the TMT. It is also a negative. My chest x ray was clear. When i will get chest pain i am getting anxiety that i will get heart attack. My brother got stroke when he was on 35yr old. Is there any chance to that i will get heart attack by heraditary. 3 months back only i did my TMT Which is negative. Can i take another TMT.
