Cardiomegaly is a medical term which is used to describe the abnormal increase or enlargement of the heart or also known as cardiac hypertrophy; It is one of the features that appear in those individuals who suffer from chronic systolic heart failure or different types of cardiomyopathies. Cardiomegaly is a phenomenon that is also known as enlargement of the heart, since this condition allows the heart to increase in size, thus affecting the ability to pump blood composed of oxygen throughout the body.

Cardiomegaly can be caused by various factors, although it should be noted that there are several of them that are more common than others. It can also be associated with numerous diseases and conditions such as congestive heart failure, hemochromatosis, and hyperthyroidism, but it is important to note that it is not caused by these.

After the ability to pump oxygen-rich blood to the body is affected, it will try to compensate for the low levels of oxygen obtained through the blood and this retribution can give way to the symptoms that are associated with cardiomegaly.

Cardiomegaly can be classified as: dilatational cardiomegaly, which originates from a deterioration that weakens the heart, an example is a heart attack. Cardiomegaly due to hypertrophy, hypertrophy generally occurs in the left heart, or in worse situations, in the entire heart. However, there are some pathologies in which there is an isolated hypertrophy of some of the cardiac chambers, among these: atrial hypertrophy (it can be left or right); and Ventricular hypertrophy, left ventricular hypertrophy, or right ventricular hypertrophy.
