Great info, thanks. For clarification:
ABI= Blood pressure in Ankle/BP in Arm
For Dr Brewer: 128/111=1.15
(You should also average 3 measurements into 1)
Thank you for the explanation!
Could you tell me please
How you get the total
128/ 111= 1.15
I would appreciate it so much.
@@lindapestridge3073
At 7.36 you can see Dr's SYS (systolic) measurements (He gets 3 times to get an average): Top ones are his blood pressure in his arm (111,111,110) and the bottom readings are his ankle readings (128,117,127). Don't worry about the DIA(diastolic) values.
Now pick one of the readings and follow the formula: 128/111=1.15
(If 3 consecutive readings are too apart, you can average them. In Dr's case they were close enough to pick one set only)
You divide 128 by 111 which results in 1.15
Isn't it strange that this guy did not explain this in the video? He just assumed that we are all doctors and that we know how to get that number? Very odd. This is why I don't watch his videos.
Just did mine. Says its perfect. Im so happy. Just lost 165 pounds.
A doctor who is interested in uncovering the truth, a doctor with a Healing stance. Thank you Doctor!
This is the best information I have ever come across! Thank you doc!
Very Informative Presentation. Enjoyed it a LOT. Thank you Dr. Brewer.
Another extremely helpful video. Thank you.
I love this and will have to try this. Many thanks for sharing Dr. Brewer!
Thanks Doc! This is the first I have heard of the ABI test. With an Omron meter I measure 1.21, no issues with HIIT on an elliptical machine. Age 69. If you have a CIMT clinic in the DC metro area I will be there.
Thank you Dr. This is such an excellent eye opener.
It is just so refreshing to hear a person speak rationally and intelligently this day and age...
Excellent information
One of the most usefull bits of "how to" DIY ... Thank You.
Very helpful. Great insight. Thank you.
Thank you so much Dr Brewer fir this informative VDO.

Thanks Doc - great video. Had not heard of this before
Thank you so much, Dr. Brewer for sharing such valuable information.
I wish all doctors were like you.
Thank you very much
Thank you! I'm going to do the plaque test!
Thanks for the great video doc. Wish you would have gone into some deaph on the CIMT🎉
Thank you for taking the time to put together these very informative videos.
Thaanks
Can you explain how you get the 1.4 number you never explained how u come up with it
Divide ankle systolic number by arm systolic number.
Loved all your past and recent videos including updates on K2 you are the man!
Thank you very much!
No, He the is Doc (lol)😀
Thank you Doctor Brewer!
What's that?...you have to climb K2 to mid-level to strengthen your heart?
Vitamin K2 needs to be taken with Vitamin/Hormone D3.
D3 helps with calcium absorption.
K2 directs the calcium to to correct places in the body.
No K2 = increased risk of heart attack through calcification.
Vitamin A is need for the K2 to do its job!
K2 has been shown to soften arteries
Mike Talley what randomised research paper proves this Mike?
How do you know that more than 1.4 and less than .9 is a problem for arteries? Do you have studies for these?
@@edwardgingerwillis7181 vitamin A is cancerogenic. Pls check studes
The video forgot to mention you divide. I was so confused until I goolged it. The Ankle Brachial Index (ABI) is the systolic pressure at the ankle, divided by the systolic pressure at the arm.
Backwards.
Thankyou for clearing that up
Wow, a Dr. With a conscience. I'm impressed
Thank you!!
Great Video , very useful. Thank you . ( Dave, UK ).
Dr. Brewer. Thank you for the valuable information you provide. It is always scientifically well supported, clearly presented, and with excellent pointers to possible courses of action. You offer the most trustworthy source of information I have come across. I particularly appreciate the nuances and frank admission when you feel the available information is not conclusive - not to mention your sense of humor.
Now that you are well buttered up :-), I do have a question on the ABI. Other videos on the subject require the use of
a device to listen to the complete stop of circulation before taking a reading whereas you only rely on the pressure monitor. Would you venture a guess on how this would affect the accuracy of the results?
The crickets are damning...
Excellent presentation on arterial plaque detection ABI sounds very simple .m.great information 👍
Reminds me of my friend who had a heart condition and the ' hospital ' prescribed adprin monthly and he passed away a few years later, of that condition. I'm hoping my other friends get better treatment
Another great, informative video Dr. Brewer! I plan to do this test on myself. BTW: your videos are looking very sharp! No need to apologize for any part of them. Thanks again for your contributions to our education.
Thanks !
Agreed
@@PrevMedHealth you should told us this: How is ankle-brachial index calculated? To calculate the ankle-brachial index, take the higher of your two systolic (top number) blood pressures from your two ankle arteries and divide that by the higher systolic blood pressure from your two arm readings.
Am turning 65 in a few weeks. Requested an exercise stress test (Bruce) on a lark. Aced the hell out of it....or so I thought. Doc who read the test interpreted a 2mm horizontal depression as either ischemia or LVH. I have my appointment with her in a month. Am totally freaked out the possibility of having an angiogram with contrast.....because I have Stage 3a ckd diagnosed 7 years ago. EGFR is still in the low 50's, but the thought of having contrast dye scares the living hell out of me due to fears of AKI. Am very jealous of your ability to keep up a 10mph pace for nearly a mile. I can only do 8.5mph for a minute. And I'm darned muscular compared to my peers. Great video, btw!
My father passed away due to PAD associated sepsis. A scan done when I was getting worked up as a transplant donor showed I had calcium in my renal arteries. I too have been walking now for over a year, 3 miles/day at 17 min/mile, which includes three hills. Doing this ABI test showed a 1.2 ratio, which is fantastic I suppose for a 67 year old. I am glad I happened to see this video!!
Hi if you have calcium in your arteries you need to take vitamin K2 : this guides the calcium to your bones not blood. Say you had a vitamin D3 deficiency you would take k2 to. Your family doctor wouldn’t tell you unfortunately. Loads of good CZcams videos on CZcams
@@Behappy62 agree entirely - I take 180mg of K2 daily - its a capsule and easy to take just the one a day.... ZERO CAC test result 10 years apart. and this ankle cuff test 121 over 67 and pulse 65 - happy with that.
@@shantishanti1949the brachial test has a score system.. it’s not about the bp itself. Look up the proper way to do it this dr didn’t explain that part.
Hello Dr. for Brewer I’ve been watching your videos for about a year and a half and I just wanna say I appreciate everything that you put out and I’ve been improving and my numbers and I did my CAC calcium test score they came up pretty good thank youp
Thank you very much.
I am so glad I found your channel. In the 70s, my dad died at age 48 of an MI. At the time, a man dying at such an early age was unheard of. My brothers went on to have heart attacks in 4heir 30s. I had bypass at age 44 being 98 percent blocked in the LAD. At age 68, I suffer from angina, Subclavian and carotid blockage. I am following your advice very closely. You make 3verything very clear. Thank you and Greetings from Tennessee.
@@PrevMedHealth You response……..shows that you are pretty caring and affectionate in helping citizens. it’s remarkable.
@SK Wish its beautiful
@@skwish6401 true hero
Have you checked your Lp(a)? Sounds like it runs in your family. My grandpa had a heart attack in 70 and ward was dead by 1978 from heart disease. He ate a lot of red meat and butter. My grandma died in 1990 in a nursing home of heart disease, she had three strokes before. All of their children except for two are still alive, my mom will be 70 in October and has stayed away from butter and red meat and has never had heart problems ever.
@@PrevMedHealth Hi i have 2 bp monitors at
Home, so i did the test using one monitor on the arm and the other on the ankle and measured the bp for ankle and arm at the same time instead of doing it one by one. I hope it is fine to do so? If anyone can confirm
Ha. The same BP monitor as me. I think the ability to do this at home will actually encourage people to check on this issue for the first time. The best thing about the ABI is that you can do it any number of times, and eventually get a good idea where you are at. I have done it a number of times, a few years ago now. Similar result to yours.
Appreciate. Very important companies for me.
Thank you for sharing!!! VERY USEFUL information!!
Thanks!
Your video on plaque extremely helpful. I had a calcium score done. It was zero. I read score was good for 10yrs (?). That was pre-pandemic . Several years ago. A few days ago I did the ABI and score was 1.16. I take warfarin since 2019 because I just happened to have free leg screen by a facility. I was avid WFPB. TO THE EXTREME. I lost @15lbs unintentionally. I guess the weight loss triggered antiphoslipid
Syndrome and was immediately prescribed the warfarin. I'm blessed to be here. My weight returned to @118. I feel so uncomfortable! I'm 5'6" Trying to be healthy as possible.

😅😂😂😂
08:11 - Were you supposed to say a significant 'increase' in systolic pressure from your arm to the ankle?
I had a CT Angiogram recently and in repsonse to your comment about "hitting a moving target", whilst true to a degree, all 3 of us being preprared were given beta blockers to lower heart rate. Mine was its norm of ~60BPM before, and just over 50 after ~20 mins. We were also coached how to hold a shallow breath for up to 15 seocnds during the procedure which further lowered the rate by a few BPM. And lastly we were told not to take any stimualnts such as caffeine for 24 hours before the procedure. Whilst not perfect, it does become less of a moving target if done properly.
I had my first heart attack DURING my first cardiac stress test!!
So i have almost total blockages in my tiny arteries of my heart all dr wants to do is super medicate me up especially with statins i aint having THAT
Really really nice sir....great
Great video! Thank you for posting 🙏🙏🙏
Thanks!
When I got my CIMT a few years ago, the doc there mentioned an emerging test that measures blood flow in the capillaries of the finger as an even better predictor of plaque than CIMT. Not sure what became of that, but I might look into it as a follow up. Any thoughts/knowledge of this test?
Thanks man, this was very intersting👍😀
Missed the key point giving the formula to calculate the ratio between the 2.
Thankyou very much for your time.
Some people like the info in a spoon.
Thanks. So true. Others don't. You can't please them all.
thank s again good doctor for the latest idea's and methods.
Thanks!
Very insightful, thanks for sharing!
Thanks.
I appreciate your intention to impart medical information valuable to your audience, and not generally explained by our imperious and busy doctors. Thank you so much.
However, I am often confused by your way of speaking. For instance: "Put the ankle over the arm.." I assume you mean divide the systolic number for the ankle reading by the systolic number for the arm reading. Please remember you are speaking to laymen here.
Additionally, you often digress mid sentence, making it hard to follow where you are going at times. Perhaps I am just being impatient; but I am much less interested in your apology for the shadow on the blood pressure monitor's screen, which I hadn't even noticed, than I am the ENTIRE chart behind you, of which you only showed results at 1 or smaller. The tantalizing words "hardening" and "specialist" were all that were visible for results of the test at 1 or above, but these seem significant, if only to put the other results in a more complete perspective.
I apologize for what may be considered negative feedback rather than helpful suggestions. I am truly grateful for your wilingness to explain these things to us at all!
My thoughts exactly. But I'd also like some guidance on placing the cuff around the ankle. Where should the tube be. With the arm it's well known. I experimented and didn't find much difference in ankle positions, but still....
@@CannabisRex that is what I have been trying to find out
did you find the answer
I didn't know whether to leave the tube
next to my feet or along my leg with the tube running up to my knee
everything is so complicated
any help would be appreciated
If you have found out .
@@lindapestridge3073 No, I haven't heard anything further, but as I said, I didn't see a significant difference in changing the cuff position.
@@CannabisRex
Thank you so much for your reply .
Maybe I’m a bit dense but for me he didn’t explain the comparison between ankle and arm vey well and the figures were not visible at top of screen.
Very useful! Thanks doc😄
Glad it was helpful!
Thank you for the info
Ford looks extremely healthy... he must be doing something right... we need his caloric daily intake... .. and his weekly meal plans...
Hi thanks for sharing your knowledge what's your thought on MPI(myocardial perfusion imaging) thanks
Not stress test upto 80 percent or above.
Only CT Angio with atleast 500 sliced machine can diagnose plaque. No trouble as non invasive .
dr. very much useful. tks very much dr, love from india
Yes, you can get a calcium score heart CT scan almost anywhere......... if you have a doctor's prescription. No place near me will do one without that. And I don't have a doctor. And no place near me even does CIMT, so that is not an option. But I am interested in this DYI method.
I've came out with 1,24 and 1,25 index. Respectively left and right. Very surprised!
I still have high(ish) blood pressure. And the veins in my legs are very visible and protuberant. In fact have always been. Even when I was younger, trained and lean.
Now 55, still with diabetes, high blood pressure, BMI 29.7. And coming out of a myriad of other issues.
The real MIRACLE (with capital letter) was getting into carnivore (newbie). Literally everything mentioned is either in ostensible remission. Or already gone!!! Yes, that's why I call it a MIRACLE! Fast, simple and easy. And curiously not even expensive! LOL 😂😂
We've have been lied BIG time.
Fat, meat, eggs, salt and water. Save lives!
great info doc
You told us what we already knew. Climb stairs 3-4 floors and if you are not breathless, it is fine. There is similarly other way out I do not want to mention which will tell you about the plaque in your arteries.
What are the odds to have identical and symmetrical differences and values for the ankles if plaques could be everywhere and of any sizes?
hello, how long time gap between each measuring? 5 mins? between arm and ankle? and them between each Ankle brachial indexes, the 3 measurements? and how about alternating right and left sides?! I did it once for my left arm and ankle, arm was 120/69 and ankle was 141/95. and then I did my right arm and ankle, arm was 121/72, ankle 138/104. do I have to repeat this 3 times for each side?!
Thanks for what you are doing but I have a suggestion: please structure your info bit more. For instance it would have been better if you explained the ratios more. Thanks
Thank you for video!
Thanks
Thank you for sharing is very interesting.👌🙏
Thank you very much
Excellent video. You can stop apologizing for your presentation. Within a year you have taken your video presentations from acceptable minimalist to extravagantly wonderful and professional. Congratulations.
Shawn Baker (Human Outliers) on the other hand is going in the opposite direction, audio and video, and his videos are now unwatchable/unlistenable IMHO. And he really doesn't care. He is the orthopedic surgeon that has been eating full carnivore for several years.
Thanks.
Yes I really wish dr Baker would get his audio fixed. His content and guests are quite good. But the audio really detracts from the experience
Question, you say if you had PAD you couldn’t do a minute of intense exercise, what would be the symptoms and would they be focussed around the lower legs ? The reason I ask is I get cold lower legs and they ache “initially” when I start to exercise , mainly the extensor digitorum Longus but this improves and goes away after 10 minutes, perhaps as nitric oxide increases??? . I have high lp(a) and very minor angina during intense exercise but this is worsening. Done a stress test, passed with flying colours, CAC =0 . Lots of ectopics during start of exercise though.
I would rather just assume we have plaque and just go for reversing it .So what are the top steps to reverse this without drugs?
JediStockTrader look into healthy ketogenic diet and intermittent fasting
Yes. And managing a proper fat mass (BMI or RFM). That’s critical.
Jedi has just asked one of the two critical questions! We need more details and actionable info in this area.
The other question is how to obtain 21st century care from a 20th century industry. How do you find a Dr. who is of this mindset?
@@PrevMedHealth what is RFM?
@@johnnytabry5519 didn't think plaque can be reversed. It can only be controlled from getting worse
can't wait to see the video on DIY brain surgery ! !
That chart is very interesting. I'd like to see the whole thing, right up to the top. And I'd like to know a little more about it. Are these ratios systolic/systolic? Diastolic/diastolic? Averages? What are they? And where was that chart published, and what science is it based on? I hold your views and opinions in very high regard, but CZcams is not a peer-reviewed scientific journal, is it.
I had a near-fatal MI three years ago, and I feel like I'm waiting for another one. I keep telling my GP that I'd like some actual knowledge about the state of my arteries. All he ever does is monitor my LDL. That's too abstract for me, and while I've asked about CIMT, it seems that here (in Nova Scotia) it's not a done thing. So I want to do this ABI test, take him the results, and (if they look significant) present them in the most compelling way I can.
Get a new dr monitoring ldl doesn’t do anything
Thank you 😊
are we subtracting leg from arm? the difference is what you're grading?
i don't get it
Couldn't understand. Just lot of other things. Not how to measure and calculate.
Based on a 02/25/2008 paper by Sutton-Tyrell et al. there are specific ABI boundaries defining normal ranges. Also proposed herein are diagnostic implications for those values which are beyond the listed boundaries. Summary:"Increased mortality was associated with low and high A.B.Index values beginning at levels of or= to 1.4." Occlusion of lower extremities is predicted at values less than 0.9. Noncompressible arteries (calcification of existing plaque) is predicted given values above 1.4. Is there more recent corroboration or refutation? Do you agree with and use these general guidelines? THANK YOU FOR COVERING THIS! I run these tests weekly on myself, but when I mention my testing to my young Cardiologist, he looks at me like I just stepped off a UFO.
Very helpful thanks
Thanks
Thank you. Interesting.
You are welcome
Doc is a ZERO CAC MRI test 10years apart of ZERO for both 10 years ago and this year a good test result ???
Also never would have thought to cuff my ankle but I did because of this video and got 121 systolic over 67 Disstolic... thinking that pretty ok at 63 yrs old. Pulse 65 ??
Amazing video Dr. Brewer. Thank you
Thanks!
So if my results are less than 1, what would be the next step? I inform my physician and what should be next?
Are the blood pressure measurements done on left or right side? Then repeat measurements are required. Again, which side? Opposites of original areas? Does it really matter which side you choose? As a nurses aide (HHA) for years, I was told by RN's to do blood pressure checks on the left arm only, except for a women who had a mastectomy on the left side.
Also, you said to put ankle pressure #'s over the arm #'s. Then what? Subtract, add, multiply, divide? This shows the percentage of arterial blockage?
Where are you getting the numbers on the chart? What are they? Points over readings on ankle over the arm?
For the DYI check comparing the arm to the ankle do you take the arm measurement with your arm at your side?
Is the ABI a proxy for diabetic physiology? Or is the reasoning behind an aberrant number independent of insulin resistance related lower body vascular function?
You need to explain. How you arrived at the index! A reader did that
Great thanks Doctor
Thanks
You are essentially subtracting the systolic of the arm from the leg in order to come up with the number on the chart? ie. if the arm is 128 and the leg is 117 the number would be 1.1 so on the chart it would be considered normal? Are the leg and the arm to be done at the same time?
Dr...do you need two separate BP meters? One for ankle and the other for arm?
Since most of us do not know how to read the BP meter, where do you see the "1". Yours was 110/62 on the meter.
The heart cath is painless and takes 5 minutes. It gives certainty. They went in through the wrist.
At 8:30, the most important part of your video you weren’t so clear Doc. You talked more about the shadow cast by your iPhone than showing the full chart and specify exactly how to use division over which? Pls edit this valuable video for normal suffering people like me, 75 yo with numbing and tingling feet, a stent on my primary artery and my doctors in LA not particularly looking in detail as they should. They didn’t tell me about ABI at all. How I wish my physician father is alive.
So is the jog uphill they at home test we can perform on ourselves?
I just had an ultrasound where they found significant plaque in one leg but I can do very fast walking for a long time without pain. I don’t know what that means or if I have coronary artery disease. The doctor saysI probably have some plaque in my coronary arteries because of my test.
So how does peripheral arterial disease relate to arterial plaque/heart disease? IE Does significant peripheral disease always identify significant heart/stroke risk?
so the ancle pressure should be equal or higher than the arm? and your using systolic or diastolic ?
How do you get the numbers from the ankle and arm measurements?
Math not explained well at al.. How did you come up with 1 and -8 and .9 ?????? When I put the ankle over the arm and subtracted , I got 22,19 and 3
ABI flags up if you have Moenckeberg's arteriosclerosis, right?
I did read some research some time ago that suggested the ABI was actually a good indicator of systemic disease process. I think it maybe something you can track over the years.
You are comparing 2 simple measurements and doing a simple calculation but somehow you went into a convoluted and incomprehensible explanation of that. How hard would be to prepare just a little bit the script for the video before hand? Amazing...
What was confusing? I found it very well presented.
Are you supposed to do the left side, right side, left side, or does it matter?
