What is the term for the enlargement of the heart?

The correct term for the enlargement of the heart is "cardiomegaly." This medical term is specifically used to describe an increase in the size of the heart and is often identified through imaging tests such as chest X-rays or echocardiograms. Cardiomegaly can be a sign of various heart conditions, including hypertension or heart valve disease, and is a key indicator used by healthcare professionals to diagnose underlying issues.

While "megalocardia" may sound similar, it is not the standard term used in clinical practice. "Cardiomyopathy" refers to a disease of the heart muscle itself, impacting its ability to pump blood effectively rather than the overall size of the heart. "Hypertrophy" refers to the thickening of the heart muscle, which can occur as a result of cardiomegaly but does not inherently mean the heart is enlarged. Therefore, the precise term that signifies overall enlargement is cardiomegaly.
