Pulmonary hypertension is a disease that can occur at any age, from infants to the elderly. Currently, pulmonary hypertension cannot be completely cured but can only be treated to reduce the symptoms of the disease.

1. What is pulmonary hypertension?

Pulmonary hypertension is an abnormal increase in pulmonary arterial pressure that may result from left heart failure, damage to the lung parenchyma, or from vascular disease, thromboembolism, or a combination of the above factors. Normal pulmonary arterial pressure at rest is 15 mmHg, and it increases by 1 mmHg every year, when mean adult pulmonary artery pressure is > 25 mmHg (at rest) it is considered hypertension. pulmonary artery.

2. What are the symptoms of pulmonary hypertension?

Symptoms of non-specific pulmonary hypertension include: dyspnea, fatigue, weakness, chest pain, syncope, and abdominal distension. Symptoms at rest only appear when the disease is severe, including: distended neck veins, hepatomegaly, peripheral edema, ascites, and cold extremities.

3. Is pulmonary hypertension dangerous?

Pulmonary hypertension if not treated aggressively, promptly and eliminated the causes of the disease, hypertension can cause dangerous complications, causing sudden death such as:
Causes right heart failure, prognosis The amount is often very severe and can easily lead to death. Increases the likelihood of blood clots forming in the pulmonary arteries, causing pulmonary infarction, if the clots cause narrowing or blockage of large blood vessels, shock and death can occur. Pulmonary artery rupture Causing arrhythmia Compression of the coronary artery stem due to pulmonary artery dilatation Coughing up blood can be life-threatening (due to bronchial artery rupture). Recent studies have demonstrated that clinical health risks associated with mean pulmonary arterial pressures (PAPs) can begin to emerge from values ​​> 19 mmHg, which is lower than the threshold. Commonly used to determine Pulmonary Hypertension (PH) is 25 mmHg.
The risk of death is increased in patients with mild pulmonary hypertension, defined as mean pulmonary arterial pressure >19 mmHg. These data highlight the need for early diagnosis of patients with mild pulmonary hypertension to be considered for inclusion in studies. This contributes to finding future drug and non-drug interventions to reduce health risks and improve outcomes.

4. Factors that worsen the patient's condition

Lung infection Hemoptysis Supraventricular tachyarrhythmia Anemia Hypertensive or hypothyroidism Edema Renal failure Excessive exertion Reduce diuretic dose or discontinue solid pulmonary vasodilator.

5. Recommendations for patients with pulmonary hypertension

Patients with pulmonary hypertension should avoid pregnancy. Strengthening immunity against influenza and pneumonia in patients with pulmonary hypertension. Psychological support for patients with pulmonary hypertension. Exercise monitoring in patients with pulmonary hypertension. If the patient is traveling by plane, oxygen support is required when the hemodynamic blood pressure is <8 kPa (<60 mmHg). During surgery, spinal anesthesia should be performed rather than general anesthesia. Treatment of anemia or iron deficiency in patients with pulmonary hypertension. Physical activity that causes symptoms is not recommended.
