title: [From left hypertrophy to heart insufficiency: hemodynamic and clinical findings].
abstract: The pathophysiology of left-ventricular hypertrophy is characterized by structural remodeling with increasing content of collagen and development of ventricular dilatation ('Gefügedilatation'). According to recent clinical view points, three stages may be distinguished: first stage, compensation, second stage, diastolic dysfunction with delayed relaxation and decrease of the passive-elastic properties, third stage, systolic and diastolic dysfunction with decreasing pump function and signs of left-ventricular failure. Diastolic dysfunction is linked to delayed rotation during isovolumetric relaxation (delayed 'untwisting') which leads to decreased ventricular filling. These changes of the myocardial adaptation process may be prevented and the vicious circle interrupted by appropriate therapeutic strategies.
