Good news!!! I had my 6 month checkup today w/ my cardiologist. Echo & ECG all say heart muscle thickening nicely and valve showing no leaks. She cut the Toprol in half to 25 MG a day, and told me to not come back for 1 year. I was very relieved to hear. Now trying to get the extra weight down. Thought I'd share my good fortune w/ all of you...my VR family....Thanks
