Heart failures can be due to an inability to PUMP effectively during systole - SYSTOLIC heart failure, or inability to FILL properly during diastole - DIASTOLIC heart failure.
Heart failure can be right-sided or left-sided .
In systolic heart failure, ventricular contraction is compromised. This may be caused by any condition that weakens the heart muscle:
- Coronary artery disease/Ischemic HD:
- Dilated cardiomyopathy
- Hypertension:
- Valvular heart disease: Damage to the valves, such as stenosis
The effectiveness of ventricular contraction is measured by the EJECTION fraction. The normal range of the ejection fraction is between 50 and 70%. In systolic heart failure, it drops below 40%.
In DIASTOLIC heart failure, the ventricle is filled with LESS blood. This may be because it is smaller than usual, or it has lost the ability to relax. The ejection fraction may be normal, but the blood output is reduced. The ejection fraction is therefore commonly used to differentiate between SYSTOLIC and DIASTOLIC dysfunction.
Examples of conditions that can lead to diastolic heart failure include:
- Hypertrophic cardiomyopathy
- Restrictive cardiomyopathy:
- Hypertension
Regardless of being systolic or diastolic in nature, left-sided heart failures share a common outcome: LESS blood pumped out from the heart. As a result, blood flows back to the lungs, where it came from, causing CONGESTION and INCREASED pulmonary pressure. As this happens, fluid leaks from the blood vessels into the lung tissue, resulting in PULMONARY EDEMA, a hallmark of left-sided heart failure. Accumulation of fluid in the alveoli IMPEDES the gas exchange process, resulting in respiratory symptoms such as shortness of breath, which worsens when lying down, and chest crackles.
RIGHT-sided heart failure is most commonly caused by LEFT-sided heart failure. This is because the INCREASED pulmonary pressure caused by left-sided heart failure makes it harder for the right ventricle to pump INTO the pulmonary artery. This results in SYSTOLIC dysfunction. In compensation, the right ventricle grows thicker to pump harder, which reduces the space available for filling, eventually leading to DIASTOLIC dysfunction. Other common causes of right-sided heart failure include chronic lung diseases which also raise pulmonary blood pressure.
As the right ventricle pumps out less blood, the blood, again, backs up to where it came from, and in this case, the SYSTEMIC circulation. This results in abnormal fluid accumulation in various organs, most notable in the feet when standing, sacral area when lying down, abdominal cavity and liver. The fluid status can be assessed by examining the distension level of the jugular vein.
Heart failure is usually managed by treating the underlying condition, together with a combination of drugs. ACE inhibitors, beta blockers are used to reduce blood pressure in patients with systolic dysfunction. Diuretics are used to reduce water retention.

This is the most concise HF explanation I have ever seen. Phenomenal stuff!
'..or it has lost the ability to relax.'
The left ventricle feels me..
I have watched numerous video’s on HF trying to learn & understand, as I suffer from this condition, apparently my readings where below 10% & I was still walking around, mind you three steps then I was gasping for air. This is by far the best video on the subject and as well as understanding the problem as well as the possible causes, I also have a better understanding of what the doctors and nurses are talking about. 10/10 Thank you and especially the doctors and nurses. 😊🙏
Thank you so much for uploading this video. I was on the verge of tears when trying to learn the mechanism, now everything is a lot more clearer
So hard & specialist professionals tropic presentation easily to understand ! So incredible our body ! We’re so lucky at all , so happy to watch this ! Thanks fo r serving !

Very nice , Thankyou
Well explanation ♥️♥️♥️
Thank you!
Thanks Couldn't understand these in College
I may have this- one doctor says " decompensated heart failure" another says "diastolic dysfunction", had cardio- testing this AM- wonder if they are both right, both wrong or 1 correct? I'm 77, so i think stiffened cardiac walls- we all may be right but I'm not planning to "push up daisies" very soon. Somehow i want fixed!😢
What is the meaning of a 120/65 blood pressure reading?
Thank you 😊
Amazing 👌
Kalsi ada terjemahan bhs infonedisnya lebijh jossss
thank you so much
Great.Thanks.
Well explained sir thanks value feedback good wishes

Recently diagnosed of grade III diastolic dysfunction with high probability of pulmonary hypertension at the age of 27. Is it dangerous?
How this estrogen affect hypertension..? Plzz
Amazing ❤️
Excellentlyyy woww 💯✨
wooooooow !!!!!! thanks alot
Thank you
Thank you somuch
Why does it end mid-sentence?
wow am doctor now
yEs
This deserves more likes
Wat?!
great....thanks a lot
Upload some videos for surgery and ortho
I think cardiac cycle phases video is a need from my site
Awesome...This how the medicine should be
Hey, I’m trying to understand diastolic HF a bit better. Why is there eventually an increase in diastolic pressure? I understand that in systolic HF, there is adequate filling, but impaired contraction, resulting in an increasing end-diastolic pressure. Can anyone clarify the process in diastolic HF? Thanks.
Hey, I hope you already got your answer you were looking for but if not, its because the left ventricle becomes thick and rigid and less able to expand. In order for it to expand enough to pump blood your body tries to increase inotropic response and force more blood into the space to force more expansion. But since pushing more blood in doesn't always work if the muscle still can't push it out, the blood backs up into the lungs.
Diastolic pressure is releted with peripheral resistance...when heart can't be relax ..the blood can't enter through right atrium...then the volume of blood will increase in superior and inferior vena cava .. which lead to increase peripheral risestnce..the increase distolic p
👌& please explain psychology topic s
Awesome
I would like to see a video where I can hear irregular heart rhythms and how they look on an EKG thank you these are very helpful
Listen!!
Cardiac murrmur sounds
You'll know it when you have them, usually. I have actual AFib and Oh, I am verrry Aware when I am experiencing those irregular heartbeats!😐 It feels like a fish is flopping all around inside your chest!!
THANKSSS
Wowoooooooooooo 👌👌👌👌👌👌👌👌♥️♥️♥️♥️♥️ very good
Nice ❤️

I have had this for a few years now I got to see the cardiologist because my heart is enlarged and the walls are starting to thicken I'm a little nervous...
Just got out of the hospital. I have diastolic heart failure. I'll pray for you.
amazing
I had this in November 29th 2020 in hospital 🏥and was in for 4 days then I went 🏡home.had heartfailure due to the stupid covid viruses that have caused the problem with the virus that has caused the problem with the most recent experience has been doing a great job with a new one and get a good feeling about it and get the vaccines to go through the process of doing things to be able to make a difference to my life as a whole lot of the person who was in a good mood for a little bit to be honest with me and to make sure it is not going to make it to a brain injuries.
Question, since normal range of EF is between 50-70%, systolic EF < 50% makes sense. But in 2:30, it says EF > 50% is diastolic, I get confused. Maybe > 70% is diastolic dysfunction? What’s the real normal range of EF? Thanks, sorry if I asked a stupid question.
Diastolic heart failure has a normal EF. Only cardiac output is reduced in diastolic HF, not EF.
I like using your videos to review complex theories, but the watermark in the middle of the animation makes me feel like I am missing something.
Dont worry you dont miss anything :) we try our best so the watermark doesn't cover any important details, and that's the best we can do for free viewing on CZcams, due to massive potential misuse and copyright thief. For those who need "clean" videos for presentation or other purposes we do offer non-watermarked versions for purchase on our website.
Does anyone know why an increase in preload would cause a decrease in left atrial contraction? I thought an increase in preload would increase contraction because of volume pressure. Please if anyone can explain
Pulmonary edema
@@anahit6645 I realized it was eventual heart failure and the heart becoming weaker! Sterling’s law can only go so far
You mean left ventricular contraction
The systemic BP is too high the heart cannot pump above it to eject blood so left sided failure

Thank you Mrs. AI woman
