The prognosis of pulmonary hypertension depends on the function of the right heart. The main symptoms in the final stage of pulmonary hypertension are those of right heart failure. At this time, the patient mainly shows symptoms such as swelling of the lower limbs, oliguria, and abdominal distension. The difficulty in breathing may be slightly less severe than in the early stages. These symptoms are mainly caused by venous congestion in the systemic circulation, which prevents blood from returning from the lower limbs, leading to edema or ascites in the lower parts of the body.

Obvious symptoms of pulmonary hypertension

Pulmonary hypertension is a relatively common disease in everyday life. Based on the causes of pulmonary hypertension, it can be divided into two categories: primary and secondary pulmonary hypertension. Regardless of the type of pulmonary hypertension, patients often exhibit certain symptoms, such as chest tightness and shortness of breath, which are the most common symptoms. In severe cases, some patients may even experience syncope. When pulmonary hypertension affects the heart, causing right ventricular enlargement, patients often show signs of right heart failure, such as shortness of breath, difficulty breathing, lower limb edema, and gastrointestinal symptoms, such as nausea and abdominal distension.

Can pulmonary hypertension cause headaches?

Pulmonary hypertension is a clinically complex disease with a wide range of causes. Consequently, the symptoms it presents in patients are numerous and complicated. Typically, patients with increasing pulmonary hypertension may experience varying degrees of shortness of breath after activity, chest tightness, dizziness, as well as chest pain, palpitations, and fainting. Generally, it does not cause headaches. However, many cases of pulmonary hypertension might also involve conditions such as hypertension, or other diseases that could lead to headaches. When pulmonary hypertension is worsening, it might coincide with an increase in blood pressure, which could also trigger headaches at that time. Therefore, it is important to differentiate in clinical practice; primary pulmonary hypertension generally does not cause headaches but can cause dizziness.

How to treat pulmonary hypertension?

Pulmonary arterial hypertension (PAH), depending on its various causes, has different treatments. The treatment commonly referred to as for pulmonary arterial hypertension specifically targets Group 1 PAH. This category of PAH has some targeted medications that are quite effective, such as prostacyclin medications, endothelin receptor antagonists, and phosphodiesterase type 5 inhibitors. These drugs target pulmonary artery pressure among other things. In addition to targeted treatments, anticoagulant therapy is usually necessary. When right heart failure occurs, diuretic therapy may be needed. In advanced stages, heart-lung or lung transplantation might be required.

Does pulmonary hypertension require oxygen therapy?

Whether pulmonary arterial hypertension requires oxygen therapy primarily depends on the patient's blood oxygen saturation level at rest. Generally, it is recommended to measure the oxygen saturation for patients with pulmonary arterial hypertension. Due to intrapulmonary shunting and shunting between the left and right heart during pulmonary arterial hypertension, arterial and venous blood mix directly, resulting in very low blood oxygen saturation in patients. Generally speaking, if the measured blood oxygen saturation at rest is below 90%, such patients often need oxygen therapy. Even if it does not drop below 90%, patients with moderate to severe pulmonary arterial hypertension also require oxygen therapy. Oxygen therapy can improve hypoxia, significantly dilating the pulmonary vessels and thus alleviating symptoms of high pulmonary artery pressure. It is very valuable for improving patient prognosis and survival time.

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.
