Info needed about PH

My cardiologist says these results are weight related but after reading of PH I am scared. I weigh 285. My first echo 10 years ago when I weighed less showed no problem. The results I will post first are from 9 mos ago. 3 mos later after a visit to lung dr with no finding of cause, the echo had remained the same. I will then post my most recent echo which looks like a change to me but the cardiologist says it is really no change. he is sending me for a sleep apnea test and wants to repeat echo in 6 mos. Would you advise waiting that long for next echo?

normal chamber dimensions
normal aortic root size
normal left ventricle wall thickness
normal left vent systolic function and wall motion
est EF 60-65%
normalvalve morpholoogy
trace to mild tricsupid regurg
moderate PH right vent systolic pressure=47
normal mitral filling pattern
no pericardial effusion

PFT borderline normal 81%
arterial gas 98%

RECENT
NEW RESULTS:
Diagnosis: Secondary Pulmonary Hypertension
This is a limited echo study to follow up on PH.
normal chamber dimensions
normal aortic root size
normal left ventricle contractillity and wall motion
est EF 65%
normalvalve morpholoogy
mild tricsupid regurg
moderate PH right vent systolic pressure=60
no pericardial effusion

Compared to study done 7/14/10, the severity of PH has remained the same.

I would agree with your Cardiologist saying that you are still considered to have moderate pulmonary arterial hypertension based off that RVSP (right ventricular systolic pressure of 60). In order to calculate your pulmonary pressures we add the RVSP to what we estimate your right atrial pressure to be and normally if your right sided pressures are not too high it is 5mmHg so your PA pressures would formally be 65mmHg (kind of complex but just trying to explain).  Here in our echo lab we say that a PA pressure between 50-70 mmHg is moderate pulmonary hypertension.  I think if you have been evaluated by a pulmonologist (lung doctor) and do not find any other causes for your pulmonary hypertension (including COPD/emphysema, chronic bronchitis, chronic thromboembolic disorders, interstitial lung diseases) then I would probably assume also that your pulmonary hypertension is due to obesity and/or sleep apnea.  I think it is very good that your doctor has ordered a sleep study and please make sure you go ahead and do this.  If you do have sleep apnea, you will be given a mask to sleep with at night which will keep your small airways open, keeping you from having apneic episodes.

Hope this helps.  Good Luck!
