Assessment of Left Ventricular Systolic Function by Echocardiography

Echocardiography serves an extremely important role in the diagnosis and management of patients with heart failure. The various stages of structural and functional changes that constitute progressive left ventricle remodeling have all been characterized by two-dimensional echocardiography. In addition, echocardiography has defined the transition from compensated hypertrophy to left ventricle dilatation and progression to end-stage heart failure. Echocardiography has also played an important role in clinical heart failure trials of β-adrenergic blocking agents and angiotensin-converting enzyme inhibitors and angiotensin receptor blockers and demonstrated their efficacy in heart failure.
