Pulmonary hypertension (PH) is a condition characterized by high blood pressure in the arteries that carry blood from the right side of the heart to the lungs. Here are some key points:

- Definition: PH is high blood pressure in the lungs due to any cause. It should not be confused with systemic hypertension, which is high blood pressure in blood vessels throughout the body.
- Types: There are five main types of PH, classified by their underlying causes:
- Group 1: Pulmonary arterial hypertension (PAH) caused by narrowed arteries.
- Group 2: PH caused by left heart disease.
- Group 3: PH caused by lung diseases.
- Group 4: PH caused by blood clots.
- Group 5: PH caused by unclear or multifactorial mechanisms.
- Symptoms: Symptoms can range from mild to severe and include shortness of breath, fatigue, and chest pain. The severity is classified into four functional classes, with class 1 being the least severe and class 4 being the most severe.
- Causes: PH can be caused by various factors, including genetic conditions, heart diseases, lung diseases, and blood clots.
- Impact: PH is a serious and progressive condition that can lead to heart failure, dangerous blood clots, and shortened life expectancy.
