Heart failure due to impaired contractile function is known as:

• A. Right-sided heart failure
• B. Diastolic heart failure
• C. Normal EF heart failure
• D. Systolic heart failure

Answer: (D)

When the heart’s pumping action is weakened, it can’t eject blood effectively with each beat. This reduced contractile function lowers the ejection fraction, so the heart fails to pump enough blood to meet the body's needs. That scenario is classic for systolic heart failure, also known as heart failure with reduced ejection fraction. In contrast, diastolic heart failure involves trouble with filling the heart because the ventricle is stiff; contraction is relatively preserved and the ejection fraction is often normal. Right-sided heart failure centers on venous congestion from the right ventricle failing, which isn’t about impaired contraction of the left ventricle. A label of normal EF heart failure implies preserved ejection fraction, which doesn’t fit the description of impaired contractile function. So, impaired contractile function best fits systolic heart failure.
