I’m fro UK. Just been diagnosed with cops by nurse at my go surgery, given inhalers and left to get on with it. I’m breathless quite a lot but had a heart attack 13 years ago and had same symptoms then. I gave up smoking then so haven’t had one for 13 years and am gutted this has happened. I’m not convinced it’s cops and not my heart. I get a lot of ectopic beats and palpitations and the inhalers make it worse. They don’t even help much. Any ideas anyone?
