I had open heart surgery about 18 months ago. They replaced part of my aorta and my aortic valve. Everything went according to plan with no issues. Now (18 months later) I have chest tightness every so often. I've seen my cardiologist numerous times and had tests done and everything related to my heart is fine (perfect as the cardiologist says). I was directed to a pulmonologist who did breathing tests, etc. and determined I'm having episodes of asthma. I had small asthma attacks as a kid (from seasonal allergy issues). They were always itchy throat and wheezing. They didn't last very long and eventually it all went away as I got older. So now I'm 60 and having what I was told are asthma episodes. But no wheezing or scratchy throat. Just lots of chest tightness where I have to raise my arms up to get a deep breath (feels like I ate too much and can't take that satisfying deep breath). And there is not rhyme or reason when they will occur. So my question: is this asthma? I've just never experienced anything like this and of course my mind always goes back to my heart repair. I trust my doctors but can't get past the fact that this started after my heart surgery. Thanks, Jeff
