It is commonly discussed when people have shortness of breath, fluid in the lungs, or reduced exercise tolerance. Clinicians use the term in cardiology, emergency care, and hospital medicine to describe a specific heart-failure pattern. It also guides how symptoms and test results are interpreted."}
