[Diagnosis and therapy of heart failure with normal ejection fraction].

Diastolic heart failure, also termed as heart failure with normal or preserved ejection fraction has a high prevalence and mortality world wide. The clinical manifestation comprises typical symptoms and signs of heart failure along with normal or discretely reduced left ventricular ejection fraction. Though the etiology of diastolic heart failure is incompletely understood, functional and structural abnormalities of cardiomyocytes, the extracellular matrix, and the peripheral vasculature are assumed to contribute to the etiology of diastolic heart failure.
