The correct answer is congestive heart failure or Congestive Heart Failure. CHF is a medical condition that occurs when the heart is unable to pump enough blood to meet the body's needs. It can cause symptoms such as shortness of breath, fatigue, and fluid retention. The term "congestive" refers to the buildup of fluid in the body, particularly in the lungs and extremities. The condition can be caused by various factors, including heart damage from a heart attack, high blood pressure, or certain diseases. Treatment for CHF may include lifestyle changes, medications, and in severe cases, surgery.
