I am new here and am having heart failure investigated as a possible diagnosis by my doctor. This journey has been going on over a year due to the pandemic. My health has deteriorated since early 2020 and I've gone from an active gym goer (an hour 5 to 6 days a week) to someone who struggles doing a 15 minute light to moderate cardio workout. I've put weight on but these symptoms started before my weight gain. I've gained largely due to exercise intolerance. The symptoms vary day to day and even throughout the day and some days are better than others. I always have bilateral feet and ankle swelling that nothing relieves, sometimes this is painful. Tried elevation, salt reduction etc. Nothing shifts it. That started months after the chest pain, shortness of breath, heaviness on chest, tiredness, cough that comes and goes etc. I've not had a heart attack, ecg came back fine. My blood pressure had gotten so bad that I was in the danger zone, I fear that this has been the case during certain periods of my life without my being aware of it. I'm now on medication for the blood pressure. My cholesterol is unusually high according to a Dr at the hospital, I have prediabetes. I'm waiting on an echo. My dad has metabolic syndrome and had a triple heart bypass but I don't know what heart condition or heart disease he had. I have pcos so I am a risk factor for all the things you don't want. I'm trying to get the weight off but with limited exercise capability it's hard. I'm scared to push myself too much in case it is heart failure. I feel like I will collapse when I exert myself these days. I managed about 30 mins exercise today and I thought my heart was going to burst out of my chest. I feel exhausted, tight chested, and like I've ran a marathon. I've been on the unfit to fit journey before and it has never felt like this. I'm just wondering if this is anything like anyone experienced prior to a diagnosis? The other two pending diagnosis are COPD and long covid (which is unconfirmed of I even had covid). I quit smoking over 8 years ago, I don't drink and don't eat a high processed diet etc. Sorry for the long post but just after some advice.
