Edema is the term used to describe the abnormal accumulation of fluid in body tissues, which occurs as a result of heart failure. When the heart is unable to adequately manage its workload, it can lead to an imbalance in fluid regulation throughout the body. This can cause fluid to accumulate in tissues, leading to swelling and discomfort. Edema is a common manifestation of heart failure and is typically observed in areas such as the legs, ankles, and lungs. Prompt medical evaluation and appropriate management are essential in addressing the underlying heart condition and alleviating the symptoms associated with edema.
