my husband had a triple bypass surgery                                         ,mitral valve repair ,a stent was put in 3-4 days before bypass and his heart was compromised ,his ejection fraction is still the same 25 since his surgery in 2006,did not improve ,he is very active and does lot of physical work,is that EF ok? he takes several meds
Maintaining same ejection fraction is also good achievement.  So not to this hearten. Be active continue medication.  If no symptom is good thing enjoy life
