Diastolic Dysfunction
Pronunciation: die-ah-STOL-ik
Impaired ventricular filling during diastole, commonly seen in elderly patients with preserved ejection fraction.
Full Definition
Diastolic dysfunction refers to abnormal left ventricular relaxation and filling properties during diastole, resulting in elevated filling pressures. This condition is particularly prevalent in geriatric patients and is often associated with heart failure with preserved ejection fraction (HFpEF). The dysfunction can be graded from mild (Grade I) to severe (Grade III) based on echocardiographic parameters. In elderly patients, diastolic dysfunction often occurs due to age-related changes in myocardial stiffness, hypertension, and diabetes.
Usage
Usage note: Often abbreviated as DD in cardiology notes; ensure distinction from systolic dysfunction.
