The medical term PHT stands for Pulmonary Hypertension.
Understanding Pulmonary Hypertension (PHT)
Pulmonary hypertension is a condition characterized by high blood pressure in the arteries that carry blood from the heart to the lungs. According to the provided reference, it is defined by a mean pulmonary artery pressure (PAP) equal to or higher than 25 mm Hg.
Key Characteristics of PHT
- Elevated Pulmonary Artery Pressure: A key indicator is a mean PAP of 25 mm Hg or greater.
- Common Symptoms: Many patients experience fatigue, reduced exercise tolerance, and shortness of breath, particularly during exertion.
- Progressive Nature: If left untreated, PHT can worsen and become a severe and potentially fatal disease.
Detailed Breakdown of PHT
| Characteristic | Description |
|---|---|
| Definition | Elevated blood pressure in the pulmonary arteries |
| Pressure Threshold | Mean pulmonary artery pressure (PAP) equal to or greater than 25 mm Hg |
| Initial Symptoms | Fatigue, decreased exercise tolerance, and exertional dyspnea (shortness of breath with exertion) |
| Disease Progression | Can become severe and fatal if untreated |
| Impact | Affects the blood vessels in the lungs. Causes increased strain on the right side of the heart as it pumps against the higher pressure. |
Importance of Early Detection
Early diagnosis and treatment of PHT are critical because the condition can be progressive. Recognizing initial symptoms such as fatigue and shortness of breath during exercise can lead to prompt medical evaluation.
