Unlike typical pulmonary hypertension, which is often caused by factors such as heart or lung diseases, CTEPH is primarily associated with unresolved blood clots in the pulmonary arteries. These blood clots can obstruct or narrow the pulmonary vessels, leading to increased resistance to blood flow and elevated blood pressure in the lungs. If left untreated, CTEPH can result in right heart failure and other serious complications.
Cause and Treatment
The exact cause of CTEPH is not always clear, but it is often linked to a history of acute pulmonary embolism, where blood clots from the veins travel to the lungs. While some individuals may recover from acute pulmonary embolism, others may develop persistent clots that lead to the development of CTEPH over time.
Treatment for CTEPH typically involves a combination of medications, such as anticoagulants, and in some cases, surgery. Early diagnosis and appropriate management are crucial for improving outcomes and quality of life for individuals with CTEPH.
