Hello, i am a 49 year old smoker with a long line of heart problems in family history. Father passed away at 53 of heart attack, mom, bypass, brother-bypass/10 stints and sister born with hole in her heart. I have high cholestrol, high BP 162/118 and do not drink alcohol. today i went for the nuclear stress test, chest xray and blood work. my question is this...i have chest pains, some very severe when going up my stairs at home and it moves down my left arm. after resting for a bit, it eases, but i also can lay down to sleep at nights and the pain hits and is so crushing that i have to sit up and try and breathe my way through it. Could this just be angina? And what would be the next step after a failed stress test?
