Just over a week ago (Sunday 30th August) I decided to go back to swimming after a 5 month break. I swam 44 lengths in 50 minutes and felt great. Next day I noticed my blood pressure was higher than normal and had a chest niggle after light warm up walk and a 30 minute run. I thought it was muscular but I did take my GTN spray(not used since Feb this year) and this and rest did seem to relieve it. This pattern continued until Friday when I decided to go to A&E. At A&E they did an ECG and took bloods & blood pressure. ECG they said compared to my HA discharge papers ECG (back in January this year) was normal for me and that whilst my troponin was raised at 15.6 but concluded this might be normal for me given my previous HA.
Conclusion was that I should be discharged that night and told to see my doctor on Monday and book an appointment at the rapid access chest clinic (RACC)-done for this Thursday)).
Spoke to my doctor this morning and he said no further sport, runs, swimming until I had the results from the RACC this Thursday. Any chest pain that does not go away with the second dose of GTN spray I should call 999.
Taking it easy until Thursday but this is all very worrying.
