6. Chronic blood clots

Blood clots are a culprit of many blood flow problems in the body. If in the arteries, they can lead directly to heart failure. Chronic blood clots found in the lungs, medically known as pulmonary emboli, can lead to PAH. However, even the scars from previous blood clots can cause symptoms. These scars block or significantly narrow the pulmonary arteries, which leads to blood flow problems and pressure. This is called chronic thromboembolic pulmonary hypertension. This condition can be exceedingly dangerous as the scar is deformed tissue that is attached to the lining of the artery wall, and it cannot be moved along or ruptured to relieve the blockage of flow.
