It commonly leads to fluid backing up into the lungs, causing shortness of breath and reduced exercise tolerance. The term is used in cardiology clinics, emergency care, and hospital medicine to describe a pattern of symptoms, exam findings, and test results. It also helps clinicians communicate severity, likely causes, and next steps for evaluation."}
