38% and Heart Failure with Reduced Ejection Fraction
QuestionChoice
There are many values present here to mislead you. In order to calculate ejection fraction, you need to know the stroke volume and the end diastolic volume. Ejection fraction = stroke volume / end diastolic volume. This is calculated as 52/92 = ~ 57%.

If the ejection fraction were <40% the classification of heart failure would be HFrEF (Heart Failure with Reduced Ejection Fraction). If it was >50%, it would be HFpEF (Heart failure with Preserved Ejection Fraction). As the ejection fraction is 57% (> 50%), this patient has HFpEF.

a
57% and Heart Failure with Preserved Ejection Fraction
QuestionChoice
This is the correct ejection fraction value. However, an ejection fraction of 57% is classified as Heart Failure with Preserved Ejection Fraction.

A 65-year-old woman attends a cardiology clinic for an echocardiogram. She is diagnosed with left ventricular heart failure secondary to aortic valve stenosis. A set of values have been measured to determine her cardiac function, and are as follows:

Systolic/Diastolic Blood Pressure: 144/96 mmHg

Heart Rate: 86 beats/min

Cardiac Output: 3.5L/min

Stroke volume: 52 mL/beat

End diastolic volume: 92 mL/beat

Which of the following describes the ejection fraction and heart failure classification of this patient's heart?
a
