Hello Barbie and my apologies for this very delayed response.
Im not even sure why you had an echo in the first place but based on the echo results, I suspect that you may indeed have mild pulmonary hypertension (though you may not have it all given how unreliable echo can be). However, even if you did have mild PH, it is not something in and of itself that you should be worried about. I am almost certain that you do not have PAH (ie the type of PH that is lifethreatening, etc). IF you have PH at all (need a heart cath to know for sure), I suspect it is simply related to getting a bit older, maybe having borderling high BP, being a bit overweight, and/or any previous smoking you've done with some lung disease, etc etc. In other words, sort of a combination of everything.
Your focus should simply be on continuing to stay active and living a healthy lifestyle along with routine medical care.
All the best,
The literature does say that COPD could lead to Pulmonary Hypertension.
The plus is that both are mild and the Dr. needs to address the COPD more aggressively so there is not so much work put on the heart and Pulmonary artery.
