This virtual assistant provides information on embolism and pulmonary hypertension, two conditions that affect the blood vessels in the lungs. It explains how pulmonary embolism occurs when a blood clot blocks an artery in the lungs, causing shortness of breath, chest pain, and other symptoms. It also covers pulmonary hypertension, a condition in which blood pressure in the pulmonary arteries is elevated, which can lead to heart failure and difficulty breathing. The assistant outlines diagnostic methods, such as imaging tests and blood work, and available treatment options. It is aimed at both individuals diagnosed with these conditions and healthcare professionals.
