you guys are so much better than the sum of professors at my school yet we still pay to learn when we can watch your videos for free

[@spencerhackwell4299]

Sadly even though institutional learning can be inferior, self education doesn’t get us degrees.

[@lcpd26]

Oh my god, I'm getting stressed knowing that, doctors learn more from KZbin rather than degree in a institution, Good greef

[@kimmememurdoch706]

Your message is so loud and clear, it makes it so much easier for everyone to understand MI pathophysiology. My husband now fully understands how MI occurs and he will make sure he doesn't promotes his partial thickness MI to full thickness MI. thanks

[@ralfcalma7383]

Can we just talk about him just casually drawing perfect cardiomyocytes and perfect lungs while I struggle to draw a house

[@yinoveryang4246]

Great video! Clearly explained in layman's terms, without being over-simplistic. Should be watched by anyone with a parent

[@NessimAbuSaif]

The plaque here is shown to be in the lumen of the vessel, later allowing the thrombus to attach to it. That's not really the case, the plaque builds up in the subendothelial layer, and increasing force/pressure in the vessels (after exertion) causes the layer (fibromuscular cap) between the plaque and lumen to rupture leading to bleeding inside the vessels, and activation of the coagulation pathway, with a thrombus being the end result.

[@MsMusicObsessed]

Brilliant video ! Love the visual aids :)

[@leonardodalongisland]

Regardless of the troponins debate, this was absolutely fantastic! Not only did it explain with great and precise accuracy what one feels/experiences during a AMI, it did a great job of explaining the internal happenings. Thank you

[@auzieaus]

u r so smart, and so good at explaining. thank you thank you so much. may God bless you and ur family.

[@caramel9614swirls]

i love you so much!!!!! this is such an easy way to understand heart attacks. thank you!!!

[@tamarapurvis1871]

I have just started my nursing degree - this explains pathophysiology so well! I actually understood and was able to use it within my case study. Thank you!

[@williammpua]

very good presentation. I am a RN and still can learn a lot from this video, thanks!

[@maryvang7324]

[@tahniyatchauhan4602]

Best video on myocardial infarction

[@ajakuk1]

I had a clot burst out of the artery in 2011. The Dr told me not many ppl live after having this. I was fully awake. I was only 33.

[@wadecrudgel6006]

Glad to hear it. I was 31 when my aorta burst and im the only person alive who survived that so yeah

[@tyleranderson2343]

Thank-you, Mark Rufallo.

[@Sherirose1]

[@nikrick5655]

Troponins aren't only found in heard muscules cells. Troponin is found in both skeletal muscle and cardiac muscle, but the specific versions of troponin differ between types of muscle. The main difference is that the TnC subunit of troponin in skeletal muscle has four calcium ion-binding sites, whereas in cardiac muscle there are only three. However troponin isn't found only in smooth muscles cells so yeah I think that you should correct that part of the video.

[@doreallyneedtodohap8734]

today one man died because of myocardial infarction... anyway nice descriptions of symptom 👍

[@Incubus187]

He just forgot to put the T and/or I after troponin, cool your jets people.

[@andreasilverio3491]

I'd love to see your explanation about MI caused by #SCAD. I had 2 heart attacks due to this rare condition where your arteries dissects forming a flap and blocking blood and oxygen flow to the heart. I'm only 43 years old otherwise fit and healthy So little is known about this condition, there is no way to prevent it as the causes still unknown and therefore there is no specific treatment either

[@Kevin-sy8uf]

Stay strong baby!

[@TheRand20]

I really hope you're okay. stay safe❤️

[@jarredyoung4458]

Awesome video. The speaker sounds like Mark Ruffalo. LOL. Fitting.

[@aureliaclarke5940]

I think. I love you.

[@professordrabhijitsayamber2299]

Om pure love Ok

[@chellappankalammc6682]

Nicely explained background video not clearly seen

[@roelvirtudes332]

I have squeezing in mychest in the left since since yesterday should i be worried?

I ON MATTERS OF THE HEART PREPARING FOR MY PRESENTATION AT UNISA PRETORIA

[@khalifadrake4514]

troponin is also found in the skeletal, , don't get confused guys ,, he made a mistake in this video

[@Justin-vg8su]

+khalifa drake While that's true, the cardiac-specific troponin is called troponin 1. This is the one specifically that you use as a biological marker after diagnosis to confirm the degree of myocardial cell apoptosis.

[@jokawild555]

+khalifa drake There's different kinds of Troponin. One of the kinds of cardiac specific.

[@paulanfreidesagun9002]

what nerve is the common origin?

[@FabryNYPD]

9:15 the cross section looks like a potato I used to eat when I was a little kid

[@28be]

why does myocardial infarction lead to increase in end-diastolic volume?

[@ryanbrunner5622]

at 6:49 you say troponins are only found in heart muscle cells, which is definitely false, they are key in skeletal muscle as well. It may be worth overriding the audio to prevent student confusion. Overall though, very helpful video -a grateful MS1

[@khalifadrake4514]

yeah, troponin is also found in skeletal muscle, ,it plays important role in skeletal tissues

[@khalifadrake4514]

[@ahaanpatkar9394]

+khalifa drake stop spamming

[@ryanbrunner5622]

Well in this case there is no implication to be made, and as a science educational video it doesn't make sense to "assume" people were gonna know that, and I'm sure that was not the intention of the video creator. "I have an idea, let's just assume they already know the whole topic, why do the video!!??" Again, you look like a fool in this thread, I don't need to insult you. I graduated in the top 7% of my undergrad, while working to fund my own tuition, offered interviews at 10+ universities (all US) including the likes of prestigious universities such as UCLA, and will graduate with my MD in 2019. So I apologize, but I won't be working as a scribe anytime soon. I hope you seek therapy, you seem mentally unwell.

[@cnaconnection]

TROPONIN IS MORE INDICATIVE OF MI.

[@fullmoon4831]

❤❤❤

[@sanatombikhumanthem1246]

❤️

[@badboi1531]

how can I cite this? pls help asap my assignment is due tomorrow

[@mgdady7367]

after 2 hour acute phase reactant are diagnostic.

[@chipichaperendon2545]

Our product clean arteries at least 18 hours, MAWA only drink 500c.c. mawarep.blogspot.com.co

[@JanelleSmith-mk5dz]

That's how my father died 😢

[@lidafubara6694]

Amazing

[@gaylecheung3087]

So you mean I’ve been dying for four years before I decided to go into the emergency was 70% blockage on my RCA, crud... eeks

[@user-dr8vc3te2d]

Guys, here's a question. In the video it was mentioned that as cardiomyocytes suffer necrosis, some toxic substances, typical for these cells, spill out from the dead cells. I wonder: what are their names?

[@luukschmitz3622]

Well, I hope I can help you... I'm a medical student studying MIs at the moment. The most important enzymes and proteins released by damaged cardiomyocytes are troponin-T (TnT), troponin-I (TnI), creatinine kinase (CK-MB) and myoglobin. There are several other important biomarkes that can be found in the blood, but these four are the most import in diagnosing a MI! I hope I answered your question!

[@psychology9065]

its all stupidly easy but we dont think of how .. we dont care if this does make sense or not we just care about As and thats exactly what modren universities want .. u pay us .. u come dump doctor or medical personnel im really afraid to ask 1uestions hat rushin my head about everything i study coz that makes me annoying

[@ineedabetterpfp2485]

Ok... Slow down, take a few deep breathes and speak slower and clearly...

[@TheALLYISLAME]

the guy whos talking sounds hot lmao

[@SimiIsLame]

the snakeu loves hobi I love hobi too snakeu

[@TheGreatWall002]

weird

[@samdottori]

Wow, it look like a thriller movie, great

[@languageandmana9255]

I'm a premed student. You are saving my educational life! You are making my very broad and detailed college course called Human diseases smooth and less hard ❤ If you were to make MCAT playlist, I would become the number one by watching your videos 😅🩵🪽 Thank you🪽🪄🙏

[@imadds6071]

Me too

[@samdottori]

Anyone knows why khanacademy is not posting videos anymore?
