I was having troubles breathing and I was heavy chested. It felt like after you run and your throat is tight and a little heat sensation. I went in to the emergency. They did an ekg ran some bloodwork and told me everything was fine. My Cardiologist suggested they do a angiogram to make sure everything was ok with my heart. I almost declined it. They went in thru my groin area and into the heart arteries and found I had two blocked arteries. They did an angioplasty and installed two stents. Its been 3 weeks now and I don't feel any better that I did when I went into the emergency room. I still find it hard to breathe and heavy chested. I use an advair inhaler and it seems to help for a little while then its back to the heavy chest. Do you know what else might be causing this.
