Karen,
Thanks for asking.
Pulmonary hypertension is actually worse than CHF, it is a primary cause of CHF and it literally takes your breath away.
My doc was in tears when she told me. Sent me to cardiologist and said do NOTHING until I see one. No walking to mailbox, no sweeping, mopping, dishes, etc. My appt is on Oct 17.
Prognosis? 3-5 yrs if goes well.
