High blood pressure in the blood vessels supplying blood to the lungs.
A serious disease in which blood pressure in the arterial network supplying the lungs with blood (pulmonary arteries) is abnormally high. The condition arises because the blood vessels in the lungs have narrowed, restricting blood flow. As a consequence, the condition may affect the heart and lead to a condition known as cor pulmonale.
A condition in which there is raised blood pressure within the blood vessels supplying the lungs (the pulmonary artery blood pressure is normally much lower than the pressure within the aorta and its branches). Pulmonary hypertension may complicate pulmonary embolism, septal defects, heart failure, diseases of the mitral valve, and chronic lung diseases. It may also develop without any known cause (primary pulmonary hypertension). The right ventricle enlarges and heart failure, fainting, and chest pain occur. The treatment is that of the cause; drugs used to control hypertension are ineffective.
In this condition, increased resistance to the blood flow through the lungs occurs. This is usually the result of lung disease, and the consequence is an increase in pulmonary artery pressure and in the pressure in the right side of the heart and in the veins bringing blood to the heart. Chronic bronchitis or emphysema commonly constrict the small arteries in the lungs, thus causing pulmonary hypertension.
Elevated blood pressures in the pulmonary arteries (above 25 to 30 mm Hg). Primary pulmonary hypertension is a rare familial illness in which small pulmonary arteries become blocked as a result of abnormalities in the structure of blood vessels in the lung. Secondary pulmonary hypertension is an elevation in pulmonary artery pressure as a result of left ventricular failure, blood clots in the pulmonary arteries, or chronic lung diseases.
An unusually elevated blood pressure within the pulmonary artery.
A condition characterized by elevated blood pressure in the arteries that deliver blood to the lungs, stemming from heightened resistance to blood flow within the lung vasculature. To sustain sufficient blood circulation, the right side of the heart must intensify its contractions. This added strain on the heart may eventually lead to the development of right-sided heart failure.
Possible origins of pulmonary hypertension encompass chronic obstructive pulmonary disease (COPD), a pulmonary embolism, pulmonary fibrosis, and specific congenital heart conditions. Nonetheless, it can also manifest without a discernible underlying cause.
Indications, such as swollen neck veins, liver enlargement, and widespread edema, materialize solely when heart failure becomes evident.
The focus of treatment targets the root cause, if identified, and alleviation of heart failure symptoms. Diuretic medications or other suitable drugs could be administered, and oxygen therapy might also be essential.
