Left ventricular diastolic dysfunction typically presents with a preserved ejection fraction.

Left ventricular diastolic dysfunction typically presents with a preserved ejection fraction.

• A. True
• B. False
• C. Not always
• D. Not specified

Answer: (A)

Left ventricular diastolic dysfunction means the ventricle has trouble relaxing and filling, not pumping. Because the issue is filling, the heart’s systolic function often remains intact, so the ejection fraction stays normal. This pattern underlies heart failure with preserved ejection fraction (HFpEF), where patients have symptoms of heart failure despite a normal or near-normal EF. There are exceptions when systolic function declines or worsens, but the typical presentation is a preserved ejection fraction.
