“High blood pressure in the arteries that supply the lungs is called pulmonary hypertension (PHT). The blood pressure measured by cuff on your arm isn’t directly related to the pressure in your lungs. The blood vessels that supply the lungs constrict and their walls thicken, so they can’t carry as much blood. As in a kinked garden hose, pressure builds up and backs up…”

“Pulmonary hypertension begins when tiny arteries in your lungs, called pulmonary arteries and capillaries, become narrowed, blocked or destroyed. This makes it harder for blood to flow through your lungs, which raises pressure within the pulmonary arteries. As the pressure builds, your heart’s lower right chamber (right ventricle) must work harder to pump blood through your lungs, eventually causing your heart muscle to weaken and sometimes fail completely…”

“In medicine, pulmonary hypertension (PH) is an increase in blood pressure in the pulmonary artery, pulmonary vein, or pulmonary capillaries, together known as the lung vasculature, leading to shortness of breath, dizziness, fainting, and other symptoms, all of which are exacerbated by exertion. Pulmonary hypertension can be a severe disease with a markedly decreased exercise tolerance and heart failure…”
