About a year ago I was diagnosed with CHF, put on Entresto, BP meds, meds for diabetes and Lasix. Lost a ton of weight and about six weeks after being diagnosed i had an echocardiogram and my RFwent from 30 to 55. I am a very low sodium diet and low carb diet. I am 51 year old female. My question is: is a flare up of CHF possible? How soon could my EF get low again? Thank you.
