Pulmonary hypertension is high blood pressure in the pulmonary arteries. These are the blood vessels that bring blood to the lung from the heart. Normal pulmonary artery pressure is 25/15 mm Hg. The mean value ranges from 12 to 16 mm Hg. So your pulmonary artery (PA) pressure of 34 is high, without a doubt. However since you are not having any symptoms this should simply be checked periodically over time. Ideally you should be under the care of a cardiologist with a special interest in pulmonary hypertension.
