The heart is the organ that pumps blood to all parts of the body, bringing nutrients and oxygen to the tissues and removing waste products. The critical functions of this vital organ can be affected by such things as coronary heart disease, drug and alcohol abuse, heart valve abnormalities, and heart muscle disease. When the heart is diseased, there are drugs and other therapies and/or surgeries available to help alleviate illness, but a transplant is an option only to remedy the most serious of heart conditions.
