This One is Interesting!
I hope you are all doing well! I have something interesting to share with all of you and hopefully you can provide some feedback. I will start by saying that I have an appointment 6/9/22 with my Cardiologist to discuss same. I've been experiencing leg weakness daily and sometimes my thighs burn when I walk as if I was doing intense exercise at the gym. I've noticed that my legs (thighs mostly) have trouble doing anything really demanding. Examples of these demanding exercises would be stairs, squats, or anything that is more of a dynamic exercise.
At work I have 4 flights of stairs from top to bottom. I can do 2.5 flights relatively easy, but by the third my heart rate is going too fast, my legs are burning and I feel the presyncope sensation coming so I stop to catch my breath. I have not fainted but it does leave me feeling awful afterward all over my body (but mostly in my chest) for about 20-30 mins. To give you some reference my heart rate when I begin is around 65 BPM and will get to around 135-140 BPM by the time I stop. I've had a CT Angiogram, numerous stress echo's (most recent 4/19/22), regular echo's and even a Cardiopulmonary Exercise Test. All of which for the most part were completely normal. I can't understand why this is happening. Now here's the kicker....
I recalled during my last business trip that when I wore compression socks they really helped me. I didn't feel much leg fatigue and there were quite a few stairs I had to tackle here and there. Long story short I decided to wear compression socks today and try the stairs at work. I was able to do 3 flights of stairs without incident. What I found odd was that my heart rate was not going as fast as it did when I was not wearing compression socks. It only maxed out at 116 BPM from around 65 BPM baseline. I could actually feel it sort of pounding harder, not faster. From there I let myself get back to baseline and I repeated the test and got the same results. My heart rate did not even hit 120 BPM! Yet again I felt like it was struggling rather than pumping fast like before.
I'll end this by saying I recently had an Ankle Brachial Pressure Index Test with Doppler which was completely normal. I've also had a Pulmonary Function Test (Feb 2022) that was normal too. I am stumped. Like I said I have an appointment with the Cardiologist but I feel it will just be more of the same. They think because all of their standard tests come back normal that nothing is wrong with me. I've been dealing with this now for a long time and still have not received a complete diagnosis. I live in Los Angeles California and have seen doctors at the VA and outside using my private health insurance. Anyhow that is my rant for the day. Thank you for listening and I'm open to any suggestions or hypothesis. All the best!
