<P> Diastolic failure is characterized by an elevated diastolic pressure in the left ventricle , despite an essentially normal / physiologic end diastolic volume ( EDV ) . Histological evidence supporting diastolic dysfunction demonstrates ventricular hypertrophy , increased interstitial collagen deposition and infiltration of the myocardium . These influences collectively lead to a decrease in distensibility and elasticity ( ability to stretch ) of the myocardium . As a consequence , cardiac output becomes diminished . When the left ventricular diastolic pressure is elevated , venous pressure in lungs must also become elevated too : left ventricular stiffness makes it more difficult for blood to enter it from the left atrium . As a result , pressure rises in the atrium and is transmitted back to the pulmonary venous system , thereby increasing its hydrostatic pressure and promoting pulmonary edema . </P>
