Patients with cardiomyopathy, a stiffening and thickening of the heart muscle that weakens it, may develop an enlarged heart as it labors to pump an adequate supply of blood to the body. Coronary artery disease, in which plaque in the arteries interferes with the flow of blood, can cause the heart to enlarge.
Things to remember. 1  An enlarged heart isnât a condition in itself, but a symptom of an underlying problem that is causing the heart to work harder than normal.  Some of the many causes include coronary heart disease, idiopathic dilated cardiomyopathy, high blood pressure and heart valve disease.
