Diastolic heart failure is defined clinically when signs and symptoms of heart failure are present in the presence of preserved left ventricular systolic function (ejection fraction >45%).

While the left ventricular end-diastolic area as determined by transesophageal echocardiography is a more accurate measure of preload than either the central venous pressure or pulmonary artery ...

At cardiac catheterization the left ventricular end-diastolic pressure was 11 mm of mercury, no valvular gradients were present, and the cardiac index was slightly reduced, 2.28 liters per minute ...

Dilatation of the veins promotes peripheral pooling of blood and decreases venous return to the heart, thereby reducing left ventricular end-diastolic pressure and pulmonary capillary wedge ...
