WHAT IS DIASTOLIC HEART FAILURE? (DIASTOLIC HEART FAILURE PATHOPHYSIOLOGY)
Diastolic heart failure is one of those trickier cardiac subjects to learn about in nursing school. So in this video, we’re going to break it down really easy for you to understand! :)
What is diastolic heart failure?
Diastolic heart failure is caused when the heart can’t relax and fill properly. This leads to a lower cardiac output, simply because there’s not as much blood in the left ventricle to begin with.
In this video, I’ll explain the 5 steps of this process during diastolic heart failure. (You won’t find these in a textbook or anything, I just made them up for you to make learning this easier!) :)
Step #1: There is a trigger or a cause (We’ll talk about some of the causes of diastolic heart failure)
Step #2: The ventricles get larger (they need to work harder and harder, causing hypertrophy)
Step #3: The ventricles can’t relax (they’ve been working so hard without a break)
Step #4: Decreased cardiac output (this is what causes those signs and symptoms of heart failure)
Thanks for watching, friend! :)

0.48 -> In this video we're diving into what diastolic
heart failure actually is.
4.72 -> You've probably heard about it in nursing
school and you definitely need to know the
9.419 -> pathophysiology for it.
10.9 -> So I'm actually going to walk you through
the 4 steps of diastolic heart failure, so
16.67 -> that you can finally understand it.
20.609 -> Let's do it.
24.279 -> My name is Christina Rafano from nursingschoolofsuccess.com
and here on the nursing school show we give
34.59 -> you the tips and resources you need to be
successful in your RN program.
41.739 -> And today, I've got another step-by-step video
for you, I know you like things broken down
48.64 -> step-by-step, and today it's all about diastolic
heart failure.
53.09 -> So when you think about diastolic heart failure,
I want you to think of big, big muscles.
59.79 -> So your heart is a muscle, right?
61.85 -> And when it works really really hard, that
muscle gets bigger.
66.54 -> And that's what's happening during diastolic
heart failure.
70.04 -> The heart has to work super duper hard, and
it's muscles, those ventricles, get bigger.
76.59 -> And when this happens, the ventricles can't
relax as much, they get really tight.
83.56 -> So let's think about this: When you go to
the gym and work out REALLY hard, your muscles
89.13 -> get bigger.
90.96 -> And what do you do afterward?
93.09 -> You stretch your muscles, or else they'll
get really tight.
97.77 -> And that's exactly what's going on here.
100.39 -> The heart has been working out so hard, but
it hasn't had a break to stretch itself out.
108.17 -> So over time, it just gets bigger and bigger,
and more tight, and the heart just can't relax.
114.59 -> So let's put this into a step by step process,
you know I'm all about the steps and I know
120.77 -> you love them too.
122.09 -> So here's a step-by-step process for diastolic
heart failure, now you won't see this anywhere
128.729 -> else, I just made it up to make learning this
a whole lot easier for you.
135.43 -> So the first step is a trigger or a cause.
138.25 -> This is something that is causing the heart
to have to work super hard.
142.819 -> So for diastolic heart failure, it could be
things like hypertension, so the heart has
148.15 -> a tough time pumping out blood into all those
smaller blood vessels, or ischemia, where
156.23 -> there's just isn't enough blood going to the
heart.
160.049 -> There's many possible causes, but it all comes
down to the heart needing to work harder,
167.23 -> or possibly genetics.
169.34 -> Now, the second step of diastolic heart failure
is that the heart works super duper hard to
174.76 -> pump that blood out, and the ventricles get
bigger and tighter.
179.09 -> And this leads to the 3rd step, which is where
the ventricles of the heart can't relax because
186.689 -> they are so tight.
188.849 -> So the ventricles are getting bigger and thicker,
and they can't relax.
192.62 -> And the 4th step, and the key really to all
of this, is a decrease in cardiac output.
198.81 -> This is a big fancy phrase for how much blood
the heart can pump out in one minute.
204.37 -> So in diastolic heart failure, the ventricles
are getting so big, so naturally, there isn't
210.969 -> as much space inside them for blood to fill.
214.79 -> So because there's not as much blood inside
the ventricles to start out with, there's
219.079 -> less blood being pumped out to the body.
221.89 -> And this is where you end up with those signs
and symptoms of heart failure: shortness of
229.219 -> breath, swelling, fatigue, crackles in the
lungs, decreased urine output, all of those
234.959 -> things.
235.969 -> Now if you're a NursingSOS member, I have
a whole video for you inside of the membership
241.209 -> community on the signs and symptoms of heart
failure.
245.379 -> It walks you through the signs and symptoms,
as well as some critical thinking so that
251.651 -> you understand the "why" behind each one.
257.03 -> So if you're a NursingSOS member, you will
definitely want check that video out.
262.79 -> And if you aren't?
263.82 -> GIRRRRLLLL, head on over there and sign up,
you are going to LOVE it!
271 -> Alright, so that is what's happening during
diastolic heart failure: the heart is working
275.44 -> so hard that is gets really big, and stiff,
and it just can't relax.
281.09 -> And this causes the cardiac output to decrease,
so the body just isn't getting as much blood
287.37 -> as it was before.
289.2 -> So I hope that helped you understand diastolic
heart failure a little better.
295.64 -> If you loved this step-by-step guide for diastolic
