Cardiac symptoms in chest ? You mean like chest pains ? I too have this occur so I went to the Hospital because I thought it was my heart . They did some tests and found nothing . I also have other symptoms .

I did a blood test , I don't know the results yet but did you know that anamenia can also cause chest pains ? Anamenia can be caused by various things but symptoms of it other than chest pains include shortness of breath , feeling tired , dizzy , being pale , tingling in hands and feet . I have alot of these symptoms which lead me to suspect I might have it , if I do the bloodtest should show it .

That's of coarse just one possibility and more likely if you also experience any of the symptoms I described .
