Diastolic Heart Failure occurs when the heart muscle becomes too enlarged and stiff to pump enough blood to the body. Heart failure decreases blood flow through the heart and blood flow to the body.

Diastolic Dysfunction is diagnosed based on Doppler ECHO - Blood flow across the mitral valve occurs in 2 phases: an early transmitral flow (E wave) and a late flow with atrial contraction (A wave). The relative contribution of each is expressed as a ratio (E/A). An E/A ratio less than 0.75 or greater than 1.5 indicates DD.
