The Major Diagnostic Groups Within Pulmonary Hypertension

An erica, i was hoping that you can remind our listeners to day about the major diagnostic groups within pulmonary hypertension. There are still five main groups. Group one being pulmonary arti hyper tension. And group two is due to left sided heart disease. and group four used to be strictly sitaor, you know, associated with clots. Now it's been expanded to include other pulmonary artery obstructions. Even anatomic obstructions are now kind of a put in that category. A sickle cell had moved from group one. It's move back and forth. It its back in hemolot hemolitic disorders in group five.
