Clarification of Ken's Heart Ejection Fraction %. Information from Google:

Ejection fraction (EF) is a measurement of how well the heart is pumping. It represents a percentage of the total blood volume in the left ventricle that is pumped (ejected) with each beat of the heart. As with any pump not all of the liquid is pumped out with each cycle.

Normal EF is in the 50-60% range. Values higher than this are termed "hyperdynamic", meaning that the heart is forcefully contracting. The lower the EF the worse the heart function. A general breakdown of values is as follows: 40-50 % mild dysfunction; 25 - 39% moderate dysfunction; < 25% severe dysfunction.


The term "ejection fraction" refers to the percentage of blood that's pumped out of a filled ventricle with each heartbeat. This measures the capacity at which your heart is pumping.
Because the left ventricle is the heart's main pumping chamber, ejection fraction is usually measured only in the left ventricle (LV). A normal LV ejection fraction is 55 percent to 70 percent.

So you don't have to worry. Ken's EF of 45% is not as bad as it sounded in the previous article. But, thanks for your concern.
