I think this saved my life when i was 34. Found 100% blockage in LAD. No heart attack. Doc said my heart basically did its own bypass. I guess this is what he was talking about.

I'm 72 years old, when I was 54 I had a mild heart attack. Over the years I had 6 stents put in my RCA for 3 blockages, 4 stents are stacked due to failures. Recently I failed a stress test. Doctor did a catherization and said the RCA is closed and that collateral arteries are supplying enough blood to the heart. The stents bought me enough time for them to form.

Nice clear explanation. My cardiologist mentioned this and your video makes it easy to understand. I had an attack when I was 50 and this was a wake-up call for me. Since then Ive been going to the gym regularly 2-3 times per week for 1 hour on the days (I'm now 67) and I am told this has helped my body to build the collateral circulation. Thanks for making this clear!

reviewing before my patho exam tomorrow, thank you!

Thank you so much!

Very good presentation. Thank You

thank yiu for making this video .

I just had a major heart attack at 42. Collateral circulation saved my life. Doctors attempted 2 angioplasties and were unsuccessful. No stents and no operations. My heart took no damage. I am researching what happened to me. Thanks for the education 👍

Thanks this helped me to understand

Thank you ma’am

You have such a gift. I have watched so many of your videos and the way you explain concepts is perfect for my learning. I have been a nurse for about 2 years and make sure I brush up on concepts. You are my go-to content creator for this! Thank you!

Awesome 😊

Thank you for the explanation :) Like many responses I've read, I'm vertical due to collaterals. I wish all of you the very best in your health and recovery - I have a damn good idea of what you may have gone through. I am 100% occluded, RCA CTO, LAD to RCA collaterals (8), LCX was same in 2 spots and collateralized as well. Its been a year and I have reduced the two LCX occlusions from 100% occluded to 90%+/- occluded and have had those stented. General health has been for the better since the 2x stenting of LCX. No more Angina and color changing fingers, hands, forearms and biceps (oh what fun that was - NOT), but still have SVT and Bradycardia, which has lessened a tiny bit. 1 more to go in RCA and we are getting close - maybe another year, or two, and RCA will be stented. Much worse in RCA vs. LCX. What to do after stenting since all this extra "pipe" (collaterals) are in use, but not necessarily any extra blood? Collateral Ablation? Leave it alone and let the body "work out the details"? Cardiology team is suggesting the later at this point as they are highly suggesting that once RCA is opened, we are likely going to have "different" issues to resolve. They are still shaking their heads that I was able to reduce the occlusion through lifestyle changes. Whatever I was doing, I turned an immediate 180 degrees and adopted the good changes immediately. How did I reduce the occlusions and how will I finally reduce RCA? I did what every doctor, school teacher, etc. has told us since we were toddlers. Exercise (need to have cardio in there) (walk to music that is 120bpm/130bpm/140bpm, and 150bpm), eat the right foods, control stress, control BP, HR, sleep, and the list goes on. 14 different "tasks" with the 15th task being time. I am just biding my time now. I have been a science project. I can see the light at the end of the tunnel and it is not a heart attack. And to circle back, timing was perfect. Had double hip replacement about 2 years before my heart attack and the surgeon said he wanted 10K steps a day out of me, so i started doing that. I book 10K steps a day before 6am now. Little did I know I was slowing getting occluded at the same time. What happened? Collaterals happened! I'm vertical. I win (for now).

Could you make a video on how to study ? I will be attending San Diego city college nursing program next year. Thank you 😊 Also , if you would make a video on fluid and electrolytes. Appreciate you 😘

She must be a professor......the explanation is mind-blowing!

Thanks for this video. I read there is some evidence you can improve coronary collateral circulation through moderate exercise. Do you have any info on other ways to increase the collateral circulation?

exceptional explanation , that's simplify the object too much

A great video, but I have questions can you live a long life with these bypass vessels if you change lifestyle, or do they only last for a few years? The collateral vessels or can they grow more

Pls bulk of collateral blood suppy when is gotten ,is it during systole or dystole?

Can collaterals form in the legs and calves too? I have a failed saphenous vein graft in my knee and I hope collaterals will grow.

How long does it take to "grow the bypass?"

My arterie is cloged but I have collateral arteries how long can someone live with the maine artery cloged I'm 50yr

i'm 36 and today i left the hospital after 12 days and it turned out that i had this exact thing happen to me. the doctors said that i more than likely i had a heart attack 8 months ago. I guess my LAD is fully closed.
