The buildup of fat in the heart makes it more difficult for the heart to function. Depending on where the buildup of fat is in the heart it can create blockages in blood flow and reduce the effectiveness of the heart to pump blood out of the heart to the lungs and body.

However, fat on the outside of the heart has a good function in addition to bad functions. For example, the atrioventricular groove, and anterior & posterior interventricular groove are fat-filled grooves that have coronary arteries and veins in them. Fat around the heart itself can also serve as a cushion for the heart.
