Four years ago I was diagnosed with PH due to sleep apnea and had a pressure of 29. Had a repeat echo last week and pressures are now at 45. Doctor said right side of my heart was beating very vigorously, which I can see. My doctor said I shouldn't be concerned and that it wasn't that serious. However, everything I read on-line states that I should be concerned and should see a professional. Should I be concerned? I have used a CPAP for the past four years since the diagnosis.
