Heart & Cardiology/Chest pain while running
I'm a 31 year old male, about 6'3 and weigh 225lbs. I was 250 lbs about 6 months ago and I am trying to get down to 205lbs. I have quite wide shoulders and generally have a larger build so I feel that is a good goal but will obviously also monitor my body fat. My question is as follows:
I usually run for 3 miles in 30 minutes. I have been noticing that when I run, around the 5-10 minute mark, I get a mild pain in my chest on the left hand side. I can make this pain go away to a degree by holding my breath and it is worse when I breathe in and out. It also tends to go away by the 20 minute mark of my run. I also notice I don't seem to get these chest pains when I play squash, but I'm not 100% sure I just don't notice because I'm concentrating on the game.
So I'm wondering if I should be worried about anything cardiac related. Would chest pain of a cardiac origin ever go away on its own during a run assuming I keep the same pace and heartrate?
I did have an episode of atrial fibrillation 2.5 years ago which was deemed lone afib. But this has left my quite concerned about my heart. I have had numerous ECGs over the years (last one was about a year ago) and had a stress ECG and a regular echo about 4 years ago. I also had a cardiologist look at my heart via and echo in an office about a year ago but I'm not sure if this counts as a regular echo. All results came back normal.
I've controlled my anxiety to a great degree regarding my heart, but I just wanted to check on this issue I'm having while running as from what I have been reading it is never a good idea to ignore chest pain.
Thanks in advance for your help.
There is nothing to suggest you a problem with your heart. As an aside, I am doubtful about that episode of A fib unless you had some major electrolyte imbalance, drug use etc. at the time. Negative cardiac tests (your stress ecg and echo) are negative tests and unless there has been a change don't need to be repeated every year just for reassurance sake!
Hope this helps,
