pulmonary hypertension

if my blood pressure is normally 100/60 but my echo showed estimated pulmonary systolic pressure 43-- would that be EXTREMELY high in my case 'coz my systemic blood pressure is on borderline low? i have increasing SOB, cough with blood seen, chest pain everyday. would that be contributed to a serious pulmonary hypertension? I am scared to death. Hope to get a reply.
God bless.

The systemic blood pressure of 100/60 is excellent. This is a measure of the pressure in all arteries, of the body, except for the pulmonary arteries. The normal pulmonary artery pressure is said to be approximately 25/15 but, as with all biologic measures, there is a range. For example, 30/18 is probably not elevated.
In normal circumstances, there is not a close relationship between the systemic and the pulmonary artery pressures. When heart failure occurs, as a result of high systemic pressures, this can result in elevation of the pulmonary artery pressures. With your systemic pressure of 100/60, this is clearly not the case. Pulmonary hypertension occurs commonly in association with COPD.
Your pulmonary artery systolic pressure of 43 would be considered mildly but definitely elevated. It is very unlikely that your shortness of breath, cough with blood in the sputum and chest pain are secondary to the elevated pressure. But, the cause of these signs and symptoms could also be the cause of the pulmonary hypertension. This situation warrants careful evaluation by a pulmonologist.
