[Diastolic left ventricular dysfunction--significance for differential diagnosis and therapy of heart failure in the aged].
The discrimination of the pathogenesis of the clinical picture "heart failure" as caused by a dominant systolic or diastolic LV-dysfunction is of a special importance in the elderly patient because of the consequences for the choice of pharmacological therapy, resulting from the age-related physiological increase of stiffness of the myocardium. The pathophysiology of diastolic dysfunction is characterized by a prolonged relaxation period as well as by compromised passive filling properties, caused by myocardial and external determinants. Typical clinical signs of diastolic dysfunction are dyspnea or pulmonary edema. Cardiac disorders with a dominance of diastolic dysfunction are coronary and hypertensive heart disease as well as hypertrophic or uremic cardiomyopathies. Diagnosis of diastolic dysfunction easily can be performed noninvasively by means of Doppler-echocardiography. Pharmacological therapy in diastolic dysfunction should prefer beta blocking drugs and calcium-antagonists against vasodilators or digitalis.
