What medical condition does the abbreviation 'CHF' refer to?

The abbreviation 'CHF' is most commonly understood to refer to Congestive Heart Failure. This condition occurs when the heart is unable to pump effectively, leading to a build-up of fluid in the lungs and surrounding tissues. The term emphasizes the congestive aspect, indicating that fluid congestion is a significant feature of the condition. While 'Chronic Heart Failure' might also describe the prolonged nature of this condition, it is not the standard terminology used in clinical practice. The focus in CHF is on the symptoms of congestion that occur due to the heart’s reduced ability to maintain adequate blood flow. Therefore, Congestive Heart Failure is the most accurate and widely accepted definition of the abbreviation.
