🫁 WHO Group 2 Pulmonary Hypertension
Group 2 pulmonary hypertension is mainly caused by left-sided heart disease. Haematologic disorders belong to a different group.
💡 First, What Does “Pulmonary Hypertension” Mean?
Pulmonary means related to the lungs. Hypertension means abnormally high blood pressure.
So, pulmonary hypertension means increased pressure in the blood vessels that carry blood through the lungs.
❤️ Why Is Group 2 Different?
The key idea is very simple:
When the left side of the heart cannot pump or fill normally, pressure backs up toward the lungs. Over time, this increased pressure can produce pulmonary hypertension.
🔑 The 3 Conditions You Should Recognize
Systolic refers to the heart’s contraction phase. Dysfunction means it is not working normally. Poor left-ventricular contraction can cause blood to back up toward the lungs.
➜ Group 2 ✔️
Valvular means related to the heart valves. Diseases of the left-sided valves, especially the mitral or aortic valves, can increase pressure behind the left heart and affect the lungs.
➜ Group 2 ✔️
Diastolic refers to the relaxation and filling phase of the heart. If the left ventricle becomes stiff, it cannot fill normally. Pressure can then rise backward into the pulmonary circulation.
➜ Group 2 ✔️
❌ Why Are Haematologic Disorders Different?
Haematologic means related to the blood. The word comes from Greek haima, meaning blood, and -logia, meaning the study of.
Certain blood disorders can cause pulmonary hypertension, but they are not the defining cause of WHO Group 2. Group 2 is specifically associated with left heart disease.
✅ Group 2 → Left-sided heart disease
🩺 Why Should Nurses Remember This?
A patient with Group 2 pulmonary hypertension may have symptoms such as:
- Shortness of breath
- Fatigue
- Reduced exercise tolerance
- Swelling of the legs
- Signs of heart failure
The nurse should pay attention to breathing, oxygen saturation, edema, blood pressure, heart sounds, and signs of worsening heart failure.
🧠 One-Line Memory Trick
If the option is a left-heart problem, think Group 2. If it is a blood disorder, don’t place it in Group 2.
Systolic dysfunction ✔️
Valvular heart disease ✔️
Diastolic dysfunction ✔️
Haematologic disorders ❌
