When people have CHF, their hearts do a lousy job of beating and pumping blood around the body. With each beat, they simply don’t pump enough blood.
The average heartbeat pushes out a little more than a quarter of a cup (or, for you drinkers, about 1.5 shots) (or for you smart science types, about 70 ml).
Someone with congestive heart failure probably pumps out about 1/8 of a cup (or .75 shots) (or 35 ml).
Here’s the part that takes some thinking to understand. There are two kinds of heart failure:
Here we’re going to discuss heart failure without preserved ejection fraction.
Let’s start by learning a little about ejection fraction.
Our blood basically travels around our bodies in a circle—They call it circulation, right? That means the heart pumps the blood out, the blood travels around the body, and then it comes back to the heart to be pumped again.
So, before each beat, the heart fills with blood….Now comes the catch— Even a healthy heart doesn’t pump all the blood in it out with each beat—it pumps out a little over half the blood in it out, or about 60%. (That means that, with each and every beat, about 60% of the blood is pumped out, and about 40% is left in.)
