@cornish I'm also a 78 yr old female. Was diagnosed with OHC in Sept of last year. I have the coughing at night for a long time, but thought it was from allergies and maybe COPD. My heart specialist told me there are 4 stages, and I was in the last stage, so my OHC is bad. I started Camzyos 4 days ago, and last night I had no coughing up of the frothy phlegm. My energy level is also up. The reason I didn't start Camzyos earlier was because I had other issues, a spot in my breast, mammograms, biopsy, plus a biopsy in ear. My husband also had knee replacement in Oct, and was busy with him. I was afraid of side effects from Camzyos, but wish I had started it sooner, as it's been great for me, so far. I have read wonderful comments on Camzyos, and a few that have said it stops working for them after awhile. I pray I'm not one of those. My doctor has told me to drink plenty of water, as it helps the heart to stay fluffy. I am also on 12.5 mg of Metoprolol daily. I was really afraid of Camzyos, as it has the Black box warnings, but I knew if I didn't take it, I wouldn't be here long. I also didn't want to have the open heart surgery (can't remember the name of that), but anyway felt I really wasn't in the condition to make it through that. I am really happy with Camzyos so far. Already way more energy too. Best of luck to you.
