Hi everyone, I was diagnosed last year with angina due to the small vessels contracting. (Microvascular I think) . This was after they suspected a heart attack and my triptomine levels increased. After a MRI my muscles didn't show damage so this is what my cardiologist as said is what he thinks it is. I had other tests showing heart problems. I have Lupus, fibromyalgia and SS syndrome. My mother and two brothers both died of heart attacks before 60. Today I learnt my only remaining brother who suffers with pulmonary fibrosis has been found to have thickening of the heart muscles which is making his breathing even worse. He has been started on tables which he says has helped a little. I have looked up thickening of the Heart muscles and it says it is a hereditary condition. It is now making me wonder if this was the problem my mother and brothers had. Can anyone help me with what exactly this is, my brother doesn't live near me so I can't really see how he is and have to rely on what he wants to tell me. He is going soon to have tests to confirm I would imagine in Sheffield. If it is hereditary should I inform my cardiologist. Thanks for any help.
