I was just diagnosed with this also. I had valve replacement in 2014 and believe this led to me getting dialated cardiomyopathy. My dr. Has me on medications to help with it. So far, I’ve seen a positive difference in my pulse and how I feel. I didn’t realize I had symptoms until I started medication...I noticed I felt better. I am pleased with my cardiologist and am following his advice. I ask a lot of questions to help me understand. That’s the best I can offer right now. I’m currently waiting for another Electro cardiogram to be done to see if I have improved...
