Management of diastolic heart failure.

Diastolic heart failure (HF) is also referred to as HF with preserved left ventricular systolic function. The distinction between systolic and diastolic HFs is a pathophysiological one and isolated forms of left ventricular dysfunction are rarely observed. In diastolic HF left ventricular systolic function is normal or only slightly impaired, and the typical manifestations of HF result from increased filling pressure caused by impaired relaxation and compliance of the left ventricle.
