My doctor diagnosed me with High BP and prescribed Toprol XL (100 mg) one a day, Diovan HCT (16-12.5 mg) one a day, Lasix (40 mg) twice a day, KLOR-CON M (20 tab) one a day. I am also a RA patient. My symptoms are lightheadedness, shortness of breath, heart palipitations, and swelling of the lower extremities (legs and feet). My doctor says I have a small amount mitral regurgitation. Is diagnosis and my symptoms, would be considered heart failure?
