Diastolic dysfunction occurs when the left ventricular myocardium is non-compliant and not able to accept blood return in a normal fashion from the left atrium. This can be a normal physiologic change with aging of the heart or result in elevated left atrial pressures leading to the clinical manifestations of diastolic congestive heart failure. There are four grades of diastolic dysfunction as described below. Echocardiography is the gold standard to diagnose diastolic dysfunction.
