Can an enlarged heart shrink back to normal size?

The answer is: it depends

An enlarged heart can sometimes shrink back to normal size, depending on the cause of the enlargement and the severity of the condition.

If the enlargement is caused by a temporary condition, such as pregnancy or high blood pressure, the heart may return to its normal size once the condition is resolved.

If the enlargement is caused by a chronic condition, such as heart disease, the heart may not be able to shrink back to normal size, but its function may be improved with treatment.
