Left Ventricular Hypertrophy (LVH) is defined as an increase in the left ventricular mass. Hypertrophy is a physiologic response to the increased wall stress from hemodynamic overload. The physiological changes become pathological with deleterious effects when the stress is prolonged. Genetic and infiltrative disorders have also been associated with hypertrophy. This book discusses the prevalence, risk factors and treatment options available for LVH.
