left ventricular dysfunction
"I am 91 and have congestive heart failure. (I also fell and broke the femur articulation with my hip in late March). My doctor gave me this medicine, Coreg, and it took away the swelling in my feet, ankles, legs and knees.  I was having such pain in my knees and the drug along with other medicines I take, that it has gotten the fluid out of my system and my knees no longer ache.  This medicine has really improved my life."
