Heart enlargement is heart failure?

Heart failure is heart failure. Enlargement of the heart is not necessarily heart failure.

If heart failure occurs, cardiac output is reduced due to decreased heart function, which cannot meet the needs of the body. The heart will respond to the needs of the body through stronger contractility, thus making the heart muscles thicker and stiffer, causing enlargement of the heart and thickening of the ventricular wall. However, in addition to heart failure, if coronary heart disease, dilated/hypertrophic cardiomyopathy, viral myocarditis, thyroid dysfunction and other diseases occur, it may also cause enlargement of the heart.
