I was diagnosed with Heart failure 2 years ago at the age of 50. My EF was 30, it improved to 70 over time. I have managing well. However, I have noticed I need much more sleep than I used to. For the last week or so, I have been very busy with work and have not been able to rest like normal. I feel like my symptoms have gotten much worse as of late - tiredness, palpitations, dizziness, shortness of breath, heart pain. I have only had edema 1 time when I was diagnosed. Am I correct in thinking that because I have not been getting the normal amount of rest, my heart is weaker?
