Having done hundreds of coronary angios I can tell you that if you had a significant "blockage" the doctor (not the hospital, a hospital is a building) would have informed you as soon as it was done. Everyone your age has some coronary calcification. Sounds like you don't have much to worry about.
Trouble is i dont trust the GP who called me and told me id rather have the letter from the hospital, my GP (i avoid her if possible) told me when i was really unwell on levothyroxine that it was not that causing it because she is on it and has never been unwell, i get awful papitations and she tells me its all in my head shortness of breath is all in my head, chest pains are anxiety the only time she ever really took notice of me was when i went to see her after having a 10 week bleed she had me referred to the hospital straight away for a scan which showed fibroids
anyhow im trying not to worry but theres a history of heart problems in my family, my mum, her mum and my uncle all died at 55 heart trouble (nan had massive heart attack and so did uncle and that was it for them, mum also had lung cancer
dad had a stroke and heart attack and was also dead by 55, my uncle has angina (not sure of his age)
ive heard nothing at all from any cardiologist so i do need to focus that if there was a problem id have heard by now
