39 yrs old. Had a suspect heart attack back in 2019 where my ef rate was 12% and was in ICU for 10 days praying for my life and coughing up pink phlegm. All the fun stuff of dying from heart failure. Luckily managed to pull through. Fast forward several years of meds and slow recovery. My ef bounced back up to 40-45% after a cadioversion that reset afib and entresto etc.
This had recently dropped down to 35-40% back in Jan and still sits around 36%. My heart is classed as moderatly impaired lv function. It has a large scar across 50%. Since starting dapa i do feel generally better overall but do get episodes of random chest pains, sharp ones. Tummy pains since starting dapa. Tiredness. Palpitations are common. etc.
My question is, how do we improve our already weakened/damaged heart, safely without compromising it and damaging it even further? What have you found that actually works to improve ef rate?
I do try to get as many steps in each day and have bought some exercise bands to try do light weights.
I was previously fit working out everyday so mentally I still want to run 5 miles a day and carry out weightlifting for fun but the trauma of it, has mentally scarred me from doing any form of exercise other than walking. How many steps should we aim for? Should we be pushing ourselves to be doing a real sweaty workout where our heart is clearly working harder or will this damage it further due to it being overworked during exercise.
