Which condition is referred to as CHF?

The term "CHF" specifically refers to Congestive Heart Failure. This condition occurs when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs. Congestive heart failure can result from various underlying issues, including coronary artery disease, high blood pressure, and damage to the heart muscle, which can lead to fluid buildup in the lungs, abdomen, and lower extremities.

While "Chronic heart failure" can sometimes be a synonym used in casual conversation, it is not the standard medical terminology denoted by "CHF." On the other hand, "Coronary heart failure" and "Coronary hypertensive failure" are not recognized medical terms. They could potentially describe specific scenarios within cardiac health but do not accurately reflect the broader and widely accepted definition of CHF as Congestive Heart Failure. Thus, the correct answer harmonizes with established medical terminology and the common understanding of the condition.
