Final answer:
Congestive heart failure is a condition in which the heart becomes too weak to pump blood effectively throughout the body. It is not caused by clogged veins or arteries. Treatment for congestive heart failure includes medication.
Step-by-step explanation:
Heart failure is a condition in which the heart becomes so weak that it can no longer pump blood throughout the body, resulting in blood pooling in various areas of the body. It is not caused by clogged veins or arteries, but rather by the impaired pumping action of the heart. While a heart attack can be a result of coronary artery disease, it is not the same as congestive heart failure. Congestive heart failure is a chronic condition that tends to worsen over time and can be managed with medications.
