I have just had the nuclear stress test (couldn't finish it due to shortness of breath) an echo cardiogram (showed minimal back flow, showing the reason behind my murmur) and a heart cath. My complaints starting out had been chest pressure, with occasional pain, thinking perhaps the bout of flu this winter had left me with walking pneumonia. Instead my family doc sent me to a heart specialist. He didn't seem to feel I was in the right spot (ever get the feeling when you fail something like a stress test they want to just say "you wimp"?) kept trying to find more there than what I could say, finally agreed to the cath. What they found was a congenital heart problem. The inside left artery crosses over and around the heart then "weaves" around the other arteries. His theory is in times of stress, the arteries expand, putting pressure on themselves and the heart. He isn't sure on doing an angio, but has set one up. My biggest question is, has any one been diagnosed and what worked for them. How many opinions do you recommend getting. If the DR didn't seem so unsure, I wouldn't be so worried.
