My father recently had sudden cardiac arrest (twelve in total) and died at the age of 59. He was incredibly fit and healthy, a keen cyclist, cycling up to 100 miles a day, didn’t drink, smoke and was a very good weight. He had an echo and clotesterol test around 6 months prior, all coming back fine. It turns out he had chronic heart disease and had 8 blocked arteries (which is incomprehensible considering his life style). My grandfather died at the age of 60 of heart attack and suffered angina for 3 years prior so the consultants have suggested we get genetic testing. I phoned the GP and they don’t know what tests to do and have asked me to contact the IDU staff to see if they can write a letter. They are incredibly busy and we still are no further forward. Any suggestions welcomed.
