An 84-year-old woman has a fall. She fractures the neck of her femur and requires emergency surgery. On history and examination, she appears to also have a possible heart failure for which an echocardiogram is scheduled. Her measurements are: End-diastolic volume: 40mL (70-240), End-systolic volume: 30mL (16-140). Calculate her approximate ejection fraction.
