Pulmonary hypertension is a very complex group of diseases. Due to different factors causing pulmonary hypertension, there are also different treatment plans for managing it. Many cases of pulmonary hypertension are quite severe at onset. To significantly enhance the patient's quality of life and ensure the stability of the condition, hospitalization is usually required for treatment. The medications used during the discharge period may vary, and some patients might need surgical intervention to alleviate some of the clinical symptoms caused by the disease. Therefore, for patients with pulmonary hypertension, if the onset is mild, symptomatic treatment through medications can be pursued. However, if the onset is sudden and severe, hospital treatment becomes necessary.

Pulmonary hypertension is seen in what disease?

Pulmonary arterial hypertension can be seen in various diseases. The first major category is arterial pulmonary hypertension. Patients may have idiopathic arterial pulmonary hypertension, familial pulmonary hypertension, and arterial pulmonary hypertension caused by related diseases. Such as collagen vascular disease, portal hypertension, HIV infection, drug or toxin-induced thyroid dysfunction, myeloproliferative disorders, splenectomy, and hemoglobinopathies can also lead to arterial pulmonary hypertension. Venous pulmonary hypertension is mostly associated with left heart system diseases, such as left atrial and left ventricular heart diseases, left heart valvular diseases. Conditions like chronic obstructive pulmonary disease, interstitial lung disease, and sleep apnea related to hypotension also lead to pulmonary hypertension. Another category is chronic thrombotic or thromboembolic pulmonary hypertension. For instance, proximal or distal pulmonary artery thromboembolism, parts such as tumors, parasites, and foreign objects can also cause pulmonary embolism, thereby causing thromboembolic pulmonary hypertension.

Early symptoms of pulmonary arterial hypertension

It depends on what disease causes pulmonary hypertension. There are several common causes of pulmonary hypertension, one of which is a pathological change in the pulmonary artery itself. Early on, there may be signs of mild increases in pulmonary artery pressure, possibly accompanied by slight right heart dysfunction. At this stage, symptoms such as mild hypotension and hypoxia might occur, manifesting as dizziness and fatigue. If the pulmonary hypertension is due to a disease of the lungs themselves, such as changes in the lung interstitium, then early symptoms of hypoxia will be more apparent, with chest tightness, slight breathing difficulties, and feelings of suffocation. If pulmonary hypertension is caused by conditions such as pulmonary embolism—specifically, an embolism in a smaller branch—the increase in pulmonary artery pressure may not be significant and will also be mild. This may be accompanied by a slight drop in blood pressure and mild breathing difficulties; however, because it is mild pulmonary hypertension, these symptoms are not severe and might include slight respiratory difficulty, mild chest tightness, shortness of breath, and mild dizziness. Therefore, early symptoms of pulmonary hypertension are typically not pronounced and generally do not attract special attention from patients.

What happens to pulmonary hypertension if you stay up late?

Because if pulmonary hypertension is not treated consistently, it can further develop into pulmonary heart disease, which is very dangerous. Patients may also experience palpitations, chest tightness, and difficulty breathing, especially after respiratory activities, where palpitations and breathing difficulties worsen. Frequent staying up late can lead to abnormal arterial hypertension in patients and cause this high pressure to continue to rise. Sometimes the condition can worsen because once patients are diagnosed with pulmonary hypertension, it is important to rest, especially to avoid staying up late, as it can cause further worsening due to vascular constriction.

How dangerous is pulmonary hypertension?

Pulmonary hypertension is itself a very complex disease, with many causative factors in clinical practice. In the early stages, patients may only exhibit symptoms such as shortness of breath after activity, difficulty breathing, and overall fatigue. However, as the condition gradually worsens, patients may experience chest tightness, rapid breathing, and even chest pain, fainting, or dizziness. If the patient also has right heart dysfunction, they may experience symptoms like swelling of the lower limbs, as well as diarrhea and abdominal distension. Therefore, if pulmonary hypertension patients are definitively diagnosed and do not receive timely appropriate treatment, the accompanying clinical symptoms may rapidly worsen. The patient's life may be at risk due to severe symptoms such as hypoxia or fainting.

Pulmonary Arterial Hypertension Mild, Moderate, Severe Classification

Pulmonary artery pressure refers to the average pressure in the pulmonary artery when the body is at rest. Generally, the normal average pulmonary artery pressure is less than 25mmHg. Pulmonary hypertension is considered when the pulmonary artery pressure exceeds 25mmHg. The grading is generally divided into three levels based on the data: the first level is mild pulmonary hypertension with pulmonary artery pressure between 26-35mmHg; moderate with pressure between 36-45mmHg; and severe with pressure greater than 45mmHg. If classified by the functional impact of pulmonary hypertension, grade I pulmonary hypertension is characterized by patients who are not limited in daily activities, and do not experience symptoms such as shortness of breath, difficulty breathing, or chest tightness after physical activity. Grade II pulmonary hypertension patients are limited by mild activities, do not feel discomfort at rest, but experience symptoms like difficulty breathing, fatigue, chest tightness, and chest pain during everyday activities. Grade III pulmonary hypertension patients have significantly limited activity; they feel no discomfort at rest, but experience symptoms like difficulty breathing, fatigue, and chest pain after only mild activity, less than everyday activities. Grade IV pulmonary hypertension is severe, with patients experiencing symptoms such as difficulty breathing and feeling tightness in their chest even at rest without any activity.
