Hi, I just wondered if anyone on here has been diagnosed with Asthma when actually they have a heart problem. I have been diagnosed with exercise-induced asthma and have tried 4 different inhalers now - none seem to help get rid of my breathlessness or cough but my peak flow readings are fine. I have gone to have an ECG yesterday and am waiting on the results but there is a history of heart problems in my family. I'm worried as the last few weeks I have been exhausted and seem to have a cough regardless of whether it has been caused after exercise or not. I had an ECG where you stay still but I wondered if I should have a stress test one where you exercise. I am not too familiar with heart problems but I just wondered if anyone has had the same or similar experience to me and whether asthma was not the issue? Also wondering how my breathing issues and cough can go away as my inhalers aren't working. I had a chest x ray which came back normal so have no chest infection. Due to see a chest specialist if my ECG comes back normal. If the ECG is fine I have no idea why inhalers aren't helping me as I'm sure it would be either lung or heart related.
