Women have hearts that are physically stronger than men
by John Thuma
PROBLEM: Find all of the instances of Ejection Fraction test results hidden in tens of millions of HL7 medical records.
WHAT IS EJECTION FRACTION:
The ejection fraction (EF) is an important measurement in determining how well your heart is pumping out blood and in diagnosing and tracking heart
failure.
A normal heart's ejection fraction may be between 55 and 70.
An EF between 40 and 55 indicates damage, perhaps from a previous heart attack, but it may not indicate heart failure.
FINDINGS: What the team was able to determine, or correlate, was that women have hearts that are physically stronger than men. Women also had less variance in their ejection fraction results throughout their lives. This is what the data demonstrated and this team is not sure if there is enough evidence to prove this point. However, it was interesting what was able to determined just be looking at HL7 text data in a statistical means.
