I have just been ready up on heart disease. I'm so scared my arteries are blocked! I'm terrified I will have a heart attack and die. I sometimes get some of the symptoms infact almost all of them. However I have had quite a Few ECG's in the past year and I had a heart monitor fittes for a few days. (24hr) plus blood work about a year ago now, would this have picked it up if I had heart disease? Could it have been missed? I'm so scared!
