As a result of high blood pressure in the arteries of the lungs, pulmonary hypertension can strain the heart and potentially result in life-threatening complications. It is essential to understand the causes, symptoms, diagnosis, treatment, and prevention of pulmonary hypertension in order to manage it effectively and improve outcomes.
Blood vessels in the lungs can be affected by a variety of factors, including:
Lung diseases that affect lung function and blood flow, such as chronic obstructive pulmonary disease (COPD).
Conditions that increase pressure in the pulmonary arteries, such as congestive heart failure or heart valve disorders.
The pulmonary arteries are blocked by blood clots or other obstructions.
The blood vessels can be affected by connective tissue diseases such as scleroderma or lupus.
Some cases of pulmonary hypertension may be caused by genetic factors.
A number of medications and drugs can contribute to the development of pulmonary hypertension, including appetite suppressants and cocaine.
Symptoms of pulmonary hypertension vary depending on the underlying cause and severity, but some are common:
A feeling of shortness of breath, especially during physical activity or when lying flat.
Weakness and fatigue.
Pain or pressure in the chest.
Edema (swelling) of the ankles, legs, or abdomen.
In advanced stages, bluish lips or skin (cyanosis).
Feeling dizzy or fainting.
Typically, pulmonary hypertension is diagnosed through a combination of medical history, physical examination, and diagnostic tests, including:
An echocardiogram is used to measure the pressure in the pulmonary arteries and assess heart function.
Lung and heart abnormalities can be visualized with an X-ray or CT scan of the chest.
An electrocardiogram (ECG) is used to assess heart rhythm and detect signs of strain on the heart.
To assess heart function and measure pressure in the pulmonary arteries, right heart catheterization may be performed.
A common treatment option for pulmonary hypertension is to improve symptoms, slow disease progression, and reduce complications.
Medications that relax blood vessels and reduce pressure in the pulmonary arteries, such as vasodilators, calcium channel blockers, or endothelin receptor antagonists.
Hypoxia symptoms can be relieved with oxygen therapy.
In order to reduce swelling and fluid buildup in the body, diuretics are used.
In certain cases, pulmonary thromboendarterectomy or lung transplantation may be considered.
In order to prevent pulmonary hypertension, it is important to manage underlying health conditions and adopt healthy lifestyle habits, such as:
Avoiding secondhand smoke and quitting smoking.
Reducing the risk of complications associated with chronic lung and heart diseases.
Maintaining a healthy weight and exercising regularly can support cardiovascular health.
Preventing pulmonary hypertension by avoiding illicit drugs and medications.
