Hi again
I was rereading my post about pulmonary hypertension and I don´t know if I explained myself fine.
"hypertension" is the same as high blood pressure. You can have high blood pressure on the arteries that come out of the left side of your heart to deliver blood to your body. That is what we usually talk about when we say that somebody has "hypertension" and is what the usually measure at the hospital or in the doctor office.
Now, the article refers to <span class="FTHighlightFont">pulmonary </span ft>hypertension, that is high blood pressure on the <span class="FTHighlightFont">pulmonary artery,</span ft> that is the one that comes out the <span class="FTHighlightFont">right side </span ft>of the heart and go to the lungs to get the blood oxigenated. the pressure of this arteries doesn´t correlate with the pressure of the arteries of the systemic circulation (the ones that deliver the blood to your body). Also there are more difficult to evaluate (only by echocardiogram or catheterism).
Another point I think is interesting is that lack of oxygen, (low sats), and very important lung damage, can also lead to pulmonary hypertension, and if you have it for a long time eventualy heart damage. That´s why they recomend you to use oxygen soon when you have low sats.
So I guess the point is that NAC is probably the same as the rest of CF medications, they´ll have to evaluate risk-benefits because you either can get pulmonary hypertension because of NAC or because lung damage and lack of oxygen. We´ll see what the new research comes to....
