I watched this video a year and a half ago, and really appreciated it's depth. It explains the process of atherosclerosis better than any other site I have found. But for the past year, I have not been able to find this video to re-watch and it has been driving me crazy (I couldn't remember my original search terms). I'm so happy to have finally found it again. I will definitely be watching more of his lessons going forward. Thank you, Dr. Wolf
I find your lectures excellent and a welcome addition to the information I am learning in class. I like the way you break things down and makes it a little easier to understand
Thanks very much Andrew. I liked that you kept the normal anatomy brief at the beginning and then went straight onto the subject of the video. Thank you :)
Thanks Andrew. I've just been diagnosed with stable angina and scheduled for a triple bypass, and the topic has suddenly become fascinating. Thanks for explaining it clearly for laymen. Now, not only do I now have more of an understanding of atherosclerosis, I can now have a more informative and intelligent discussion with the cardiologist.
BIG THANKYOU for this great visual explanation of the pathophys of athersclerosis! I am studying ACS as part of my post-grad studies in my Emergency Nursing and I found this explanation of yours EXTREMELY useful in understanding the whole complicated process. I love your diagrams... will be copying them in my notes :) Big Hello from Perth, Australia!
I have an exam next week for my Adult Nursing course (Scotland) and your videos are great for revision! The information you give links perfectly to my lecture notes but I am very much a visual learner and so your videos are great for me. Thank you so much for spending time to make them and kindly sharing them with the UA-cam community. Oh, and something tells me your view count is going to increase significantly over the next week. My class are sharing your videos on our private facebook page!
Andrew Wolf you did not talk about the process of CALCIFICATION, when the fibrous cap becomes stiffer and more brittle and more prone to rupture. The calcification process also affects blood pressure behavior due to the lesser elasticity of the arterial volume...
My prof tolled us to study the kinds of atherosclerosis plaques I was reading Robbins basic pathology book 7th edd chapter 9 and I still dont understand what kinds did he mant . Your help will be so gratitude! Thank you!
Hi Andrew, thank you for the video. How actually can the plaque grow in size after a fibrous layer is formed around the plaque as the opening in the intema is closed by the fibrous layer so how they enter?
Nice video. Why doesn't the platelet plug prevent the LDL deposition? Once the fibrous plaque forms, why doesn't that prevent further LDL deposition? Why doesn't the coagulation/inflammation process proceed as it does in other locations and produce proper healing?
I found that the key problem is the high blood pressure. If it occurs suddenly and very strongly then a plaque can rupture, and a piece can break off and travel downstream and block the artery.
it helped me a lot....its a different approach to pathophysiology and i enjoyed ur lecture.i would like to ask u if der is any lecture regarding how tobacco causes endothelial injury i.e by antiprotease hypothesis and antioxidant mechansim.if u included these explanations under any other disease plz let me know.... plz sir
Hello, first of all thank you for the wonderful informative video. I enjoyed it. I was just wondering if you have a made a video about the role of PI3Ks in cardiovascular disease? Thank you
Great lecture! it's true that this visual way of learning makes it sooo much easier than just reading my lecture notes- much thanks! One thing though- at the end of the lecture you mention the clot breaking off and causing an embolism somewhere- can the plaque break off and do this too? Is this also called an embolism?
Hi, I was wondering if you could possibly cover physiology of aging? Thank you so much for all your videos and teachings, they are helping me through medical school.
Question: in stage 3. Fibrous plaque. You said it won't have contact with the blood stream anymore. So how can it grow in size if LDL's are floating in blood stream? Just got confused in this part. Thank for you videos. It's very helpful and I'm a fan!
Subscribed soon after watching this. such a good revision tool for me, and i'm doing a degree! One question though; after the fibrous cap has formed isn't there another process of 'calcification'? if so what actually causes it?
Very good explanation. Thank you! Do macrophages go into the break in the intima first, or do monocytes come first and then convert them to macrophages?
thanks alot doctor ***** ... but i have one question after the fibrous plaque formation ...from where does the LDLs come from ?? i mean Macrophages will engulf the LDLs and will grow to some distance ...then how does it keep growing ?? ....or is that the LDL enter in a very large quantity that it takes alot of time to be engulfed by macrophages ?? please anyone answer :D
I believe that the LDL is recruited by the endothelial cells, since LDL contains cholesterol and other molecules that the cells need - after all, the reason that LDL is circulating is to bring nutrients to the cells. Therefore if you have a high level of LDL in the blood over an extended period of time, more of it is recruited and also more of it can be oxidized (this isn't mentioned in the video but oxidation of LDL is pretty bad and can increase inflammation because the immune system recognizes the OxLDL (it can even produce antibodies against it)). Therefore the oxidation of LDL only increases the rate of development of atherosclerosis, since it increases inflammation. Even though the fibrous plaque covers the developing core, the endothelial cells below it still the LDL contents. I'm not a doctor (just a student) so take this with a grain of salt, but I hope that it helps.
very good lecture, you just taught me the easy way to understand atherosclerosis process. theres no much feedback from me, but you may just speak more clear and louder. because in some part, your voice getting quite, especially when you saying the important point. thank U so much, keep publish more lectures about important topics :)
What causes the LDL particles to stick to the tunica intima and get under the layer ? What attracts them ? Chemokines, like what happens with lymphocytes ?
+Joe Kensei As far as I know, hyperlipidaemia contributes to driving the LDL into the intimal layer. LDL is retained via association of ApoB-100 with negatively-charged proteoglycan residues in the ECM.
Thankfully my exam has been a good excuse for staying indoors and studying. I can see the snow on the hills from my window right now :/ It doesn't look too inviting!
i'm a 5th year med student and your video helped me understand atherosclerosis way more. clearly. words can not express my gratitude.
You’re welcome. Glad you found it helpful!
Thanks! UA-cam extends the reach of your talent for explanation to people all over the world

Hi Andrew, thank you for the video.
How actually can the plaque grow in size after a fibrous layer is formed around the plaque as the opening in the intema is closed by the fibrous layer so how they enter?
very helpful! thank you Andrew :)
Thank you for watching. Glad it helped!
Awesome video! i just dont understand how the plaque continues growing under the fibrin, when is not exposed to more LDL... THANKS!
Nice video. Why doesn't the platelet plug prevent the LDL deposition? Once the fibrous plaque forms, why doesn't that prevent further LDL deposition? Why doesn't the coagulation/inflammation process proceed as it does in other locations and produce proper healing?

Hi - Could you expand on how DM contributes to the plaque formation, inflamation or maybe the rupture?
Thanks so much for your inquiry. We have passed this question on to our medical review team. Thanks again for watching!
I found that the key problem is the high blood pressure. If it occurs suddenly and very strongly then a plaque can rupture, and a piece can break off and travel downstream and block the artery.
Awesome video once again. I am just now wondering how can LDL molecules cause inflammation by themselves?
Really helpful, thanks x
