There are usually two methods to measure pulmonary arterial hypertension. One is through echocardiography to estimate, by measuring the speed of tricuspid regurgitation and then calculating the systolic pressure of the pulmonary artery through a formula. This method may overestimate or underestimate, hence its accuracy is not reliable. The gold standard is measuring pulmonary artery pressure via right heart catheterization. The downside of this gold standard is that it is an invasive procedure, which needs to be performed in a catheterization room; compared to ultrasound, it is also more costly. These are the two methods, each with its pros and cons. We need to choose based on the patient's situation.

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.

How to diagnose pulmonary arterial hypertension?

To accurately diagnose pulmonary hypertension, the following aspects should be considered: symptoms, signs, laboratory, and other tests. Early-stage pulmonary hypertension usually doesn't exhibit clear symptoms, but discomfort occurs during intense activities. Common symptoms include difficulty breathing, chest pain, dizziness or fainting, and coughing up blood. Additionally, patients should undergo laboratory tests such as blood tests including liver function tests and HIV antibody testing, serological tests; an electrocardiogram to check for right ventricular enlargement or hypertrophy; chest X-ray; echocardiography and Doppler ultrasound; pulmonary function tests; blood gas analysis; radioactive isotope lung ventilation/perfusion scan; right heart catheterization; and lung biopsy.

What to do with mild pulmonary hypertension?

Pulmonary artery hypertension is a relatively common disease in daily life. Based on the different pulmonary artery pressures, it can be divided into mild, moderate, and severe pulmonary artery hypertension. When the right heart catheter measures pulmonary artery pressure between 30 to 50 mmHg, this situation often belongs to mild pulmonary artery hypertension. So, what should one do if diagnosed with mild pulmonary artery hypertension? Generally, mild pulmonary artery hypertension is not serious and usually does not cause noticeable symptoms, so no special treatment is needed. However, having mild pulmonary artery hypertension does not mean it can be taken lightly. It is important to undergo regular examinations under the guidance of a doctor, identify the cause of the increased pulmonary artery pressure, and treat the symptoms timely.

Pulmonary hypertension is treated by which department?

Pulmonary arterial hypertension is a common clinical condition with complex causes, and depending on the cause, patients may visit different departments. The common causes of pulmonary arterial hypertension include the following. The first type is venous pulmonary hypertension, which is caused by diseases of the left heart system. Patients with this condition need to visit the department of cardiology, mainly to control heart failure. The second type is chronic thromboembolic pulmonary hypertension. The main reasons include thromboembolism in the proximal or distal pulmonary arteries, or due to tumors, parasites, foreign bodies, etc., leading to pulmonary embolism. Diseases of this type require visits to the respiratory department. Additionally, chronic pulmonary heart disease, such as heart failure caused by chronic obstructive pulmonary disease, interstitial lung disease, sleep breathing disorders, and hypoventilation lesions, also lead to pulmonary arterial hypertension and should be treated in the respiratory department. Furthermore, some rheumatic immune diseases and congenital heart diseases can also cause pulmonary arterial hypertension. As pulmonary arterial hypertension has gradually received more attention, some hospitals have established specialized outpatient clinics for pulmonary arterial hypertension.
