Remodeling of heart
When the left ventricle is damaged—for instance, by a myocardial infarction (heart attack) or by cardiomyopathy—changes often occur in the size and shape of the ventricle.1The ventricle tends to become enlarged, its general shape becomes more globular and less elliptical, and the muscular wall of the ventricle … See more Doctors can assess whether cardiac remodeling is present, and can follow the extent of remodeling over time, with imaging studies that allow them to assess the size, shape, and … See more While it has been known for many decades that cardiac enlargement and a reduced LVEF are bad, the concept of “cardiac remodeling” has been in common usage among cardiologists only since the 1990s.
