what causes a mildly enlarged heart
An enlarged heart may have several causes. But it's usually the result of high blood pressure or coronary artery disease. It may not pump blood effectively, which can bring congestive heart failure. It may improve over time. But most people with an enlarged heart need life-long treatment with medications.
In particular, an enlarged heart is a common cause of heart failure. The right and left sides of your heart do different jobs. The right side takes in blood that has travelled round the body and pumps it to the lungs. From here, the blood enters the left side of the heart from where it is pumped all round your body.
