It occurs when blood clots pulmonary embolism block the flow of blood in arteries and blood pressure in the lungs increases. The main symptom of pulmonary hypertension is shortness of breath or dyspnea.
The increase in blood pressure associated with pulmonary hypertension causes changes in the cells that line the pulmonary arteries making them stiff and thick and. In other cases there is another condition thats causing the problem. This is the most common cause.
Pulmonary hypertension is a form of high blood pressure in the vessels that connect the heart to the lungs. Other causes of pulmonary hypertension. Group 1 pulmonary arterial hypertension PAH Group 1 PAH can have a variety of causes including.
It is believed the disease may be caused by damage to the cells that line the arteries of the lungs. Group 2 pulmonary hypertension is often associated with left heart disease such as mitral valve disease or long-term high blood pressure.
