Hi. After 2 heart attacks and seven stents things were going well but over the last few weeks I am experiencing severe tiredness and get breathless after doing the smallest activity. I was told 1 year ago that I have left ventricular systolic dysfunction with ejection fraction of 38. I recently had a perfusion test my cardiac nurse emailed me to tell me that it was good news the perfusion was normal. My GP is arranging a sleep clinic session to see if my sleeping is causing a problem as my partner has said I stop breathing during my sleep. Was just wondering if anyone else is suffering from fatigue and weakness.
