Does high blood pressure cause a pulmonary aneurysm?

High blood pressure (hypertension) can contribute to the development of various cardiovascular conditions, including aneurysms in the aorta, but it is not a direct cause of pulmonary aneurysms. Pulmonary aneurysms, which occur in the pulmonary arteries, are more commonly associated with conditions such as pulmonary hypertension, infections, or congenital heart defects. While hypertension can exacerbate existing vascular problems, it is not the primary cause of pulmonary aneurysms.
