Definition
By Mayo Clinic staffLeft ventricular hypertrophy is enlargement (hypertrophy) of the muscle tissue that makes up the wall of your heart's main pumping chamber (left ventricle).
Left ventricular hypertrophy develops in response to some factor, such as high blood pressure, that requires the left ventricle to work harder. As the workload increases, the walls of the chamber grow thicker, lose elasticity and eventually may fail to pump with as much force as a healthy heart.
Left ventricular hypertrophy (LVH) is more common in people who have high blood pressure or other heart problems.
