Overview

Cardiomegaly is most often linked to high blood pressure, but it can also occur as a result of other heart conditions, such as congestive heart failure, and other non-cardiac causes such as long-term anemia. A common cause of left ventricular hypertrophy is chronic hypertension, which increases the afterload on the left ventricle. Some cardiac hypertrophy is normal and reversible, such as that seen in athletes and pregnant women. The common causes of cardiomegaly due dilation of the myocardium are dilated cardiomyopathy (non-ischemic cardiomyopathy) and ischaemic heart disease.
