Pulmonary Hypertension Categories Explained by Dr. Muhammad Waqas


I’m Dr. Muhammad Waqas. I work at CHI St. Vincent Heart Institute. I’m specialized in advanced congestive
heart failure and pulmonary hypertension. So, over time the World Health Organization
symposiums have led to the definition of five distinct groups of pulmonary
hypertension and those are based upon where the disease process is. For example, if
patients have lung conditions they fall in the group three
part of the WHO, World Health Organization classification of pulmonary hypertension. Patients who have sickle cell disease or patients who have sarcoidosis
they fall into group five. Similarly, patients who have conditions such as
rheumatoid arthritis or patients who have a history of scleroderma or patients
who have history of hepatitis C, patients who have congenital disorders, patients
who have unknown cause of pulmonary hypertension they fall in Group one of
of of the symposium definition. Also, patients who have bad left heart
disease such as low heart function, stiff heart function, bad rhythm issues, bad
valve issue, they fall in group two of pulmonary hypertension. So, based on these
categories, based on the symptom onset history manifestation and
diagnostic strategies we put patients in the specific groups if we can, so we can
target and treat patients based on those those specific group plans.
