Elevated pulmonary vascular pressure.

Increased pressure with the the pulmonary circulation, usually secondary to cardiac or pulmonary disease.

Increased pressure within the pulmonary circulation due to lung or heart disorder.

Pulmonary hypertension, sometimes called PH, is a serious condition that affects the blood vessels in the lungs. It develops when the blood pressure in your lungs is higher than normal. Your heart pumps blood to your lungs so they can add oxygen to the blood. The blood goes back to your heart. From there, it travels to the rest of your body so that your tissues can get the oxygen that they need. The blood moves from your heart to your lungs through blood vessels called pulmonary arteries. If the pulmonary arteries become damaged, narrowed, or blocked, the blood does not flow through them as well. This can increase the blood pressure in the arteries and cause pulmonary hypertension. There are different types of pulmonary hypertension, including pulmonary arterial hypertension (PAH). The different types are based on what caused the disease. Pulmonary hypertension can develop on its own or be caused by another condition. Sometimes the cause is unknown or is not clear. Some of the possible causes include: Heart diseases, including left-sided heart failure and congenital heart disease; Lung diseases such as COPD (chronic obstructive pulmonary disease), interstitial lung disease, emphysema, and sleep apnea; Other medical conditions such as: Liver diseases; Sickle cell disease; Pulmonary embolism (blood clots in the lungs); Connective tissue disorders like scleroderma. . Certain factors can make you more likely to develop pulmonary hypertension, such as: Your age. The risk increases as you get older. The condition is usually diagnosed between ages 30 and 60.; Your environment. Being exposed to asbestos or having certain infections caused by parasites can raise your risk.; Your family history and genetics. Certain genetic disorders, such as Down syndrome, congenital heart disease, and Gaucher disease, can raise your risk of pulmonary hypertension. So can a family history of blood clots.; Your lifestyle habits. Smoking and illegal drug use can raise your risk of developing pulmonary hypertension.; Certain medicines. For example, some medicines used to treat cancer and depression can make you more likely to develop pulmonary hypertension.; Your sex. Pulmonary hypertension is more common in women than in men. The symptoms of pulmonary hypertension are sometimes hard to recognize and are similar to the symptoms of other medical conditions. So sometimes it can take years for someone to get diagnosed with pulmonary hypertension. The symptoms of pulmonary hypertension may include: Shortness of breath; Chest pain or pressure; Dizziness that may lead to fainting; Fatigue; Swelling of the abdomen, legs, or feet; Heart palpitations (the feeling that your heart is pounding or beating too fast).

(hypertension, pulmonary) Increased VASCULAR RESISTANCE in the PULMONARY CIRCULATION, usually secondary to HEART DISEASES or LUNG DISEASES.

A disorder characterized by an increase in pressure within the pulmonary circulation due to lung or heart disorder.

Pulmonary hypertension is increased pressure in the pulmonary circulation. It has many secondary causes; some cases are idiopathic. In pulmonary hypertension, pulmonary vessels become constricted and/or obstructed. Severe pulmonary hypertension leads to right ventricular overload and failure. Symptoms are fatigue, exertional dyspnea,...

Pulmonary hypertension is a type of high blood pressure that affects the arteries in your lungs and the right side of your heart.
