Pulmonary hypertension (PH) prognosis can vary based on several factors, including the type of PH and the individual's overall health. Here are some key points from my knowledge base:

- Functional Classes: The World Health Organization (WHO) divides PH into four functional classes based on symptom severity:
- Class 1: No symptoms at rest or with exercise.
- Class 2: No symptoms at rest, but shortness of breath during everyday activities.
- Class 3: No symptoms at rest, but significant limitations during everyday activities.
- Class 4: Symptoms at rest and during activities, with common swelling of ankles and feet (edema).

- Survival Rates: Survival times depend on factors like sex, age, overall health, and underlying conditions. For example, Group 3 PH (due to lung disease and hypoxia) has a five-year survival rate of 44% for women and 34.3% for men.

- Types of PH: The WHO categorizes PH into five groups based on the cause:
- Group 1: Pulmonary Arterial Hypertension (PAH)
- Group 2: PH due to left heart disease
- Group 3: PH due to lung disease and hypoxia
- Group 4: PH due to chronic thromboembolic disease
- Group 5: PH with unclear or multifactorial mechanisms
