rops in scores all the time. Many have done it without l-arginine.
Now, how about the people who have failed to stop a rising score? Would they do better with l-arginine as part of the mix? I believe so, but sometimes we never quite know except in retrospect. It has been a great dilemma for us trying to predict from the starting gate who will or who won’t drop their heart scan score.
My view from the trenches is that l-arginine packs its greatest atherosclerosis-fighting punch in the first year or two of use, when “endothelial dysfunction” is likely to be present (abnormal artery constriction). But as all other strategies take hold—fish oil, correction of lipid and lipoprotein abnormalities, weight loss (big effect), vitamin D (another very big effect), etc.—endothelial behavior improves over time. Perhaps l-arginine becomes a less necessary component over time.
There’s no doubt that uncertainty still surrounds the use and science surrounding l-arginine. However, if you’re interested in stacking the odds in your favor, particularly during the first year or two of your plaque-reducing efforts, I think that l-arginine is worth considering. It is cumbersome, it can be expensive, some preparations may even be foul. But in the big picture of life, with hospitals trying every possible ploy to get your body on a table for a procedure, doctors perverting their mission by signing employment contracts with hospitals and agreeing to usher you into the hospital as a paying patient whenever possible, and drug companies viewing you and me as a market for medications which may or may not be helpful, l-arginine is surely not that big a burden.
If you're a Track Your Plaque Member or viewer, you may know that we have resisted outside commercial involvement. We do not run advertising on the site, we do not allow drug companies to post ads, we do not covertly sponsor supplements. We do this to main the unbiased content of the site.
We've seen too many sites be tempted by the money offered by a drug company only to see content gradually drift towards providing nothing more than cleverly concealed drug advertising. I personally find this deceptive and disgusting. Ads are ads and everyone knows it. But when you subvert content, secretly driven by a commercial agenda, that I find abhorrent.
That said, however, I do wonder if we need the participation of some outside commercial interests to help our members. In other words, many (over half) of the questions and conversations we have with people is about what supplement to take, or what medication to take. While we cannot offer direct medical advice online (nor should we) because of legal and ethical restrictions, I wonder if could facilitate access to products.
Many people struggle, for instance, with trusted sources for l-arginine, vitamin D, fish oil. Other people struggle with finding a heart scan center because of the changing landscape of the CT scanning industry. Could we somehow provide a clear-cut segment of the website that clearly demarcates what is commercial and non-Track Your Plaque-originated, yet at least provides a starting place for more info?
Ideally, we would have personally tried and investigated everything there is out there applicable to the program. But that's simply impossible at this stage.
I feel strongly that we will never run conventional ads on the site. Nor will we ever permit any outside commercial interest to dictate what and how we say something. The internet world is full of places like that. Look at WebMD. I find the site embarassing in the degree of commercial bias there. We will NEVER sell out like that, regardless of the temptation. People with heart disease are all conducting a war with the commercial forces working to profit from them--hospitals, cardiologists, drug companies, medical device companies (yes, even they advertise to the public, e.g., implantable defibrillators--no kidding). Genuine, honest, unbiased information is sorely needed and not from some kook who either knows nothing about real people with real disease, or has a hidden agenda like selling you chelation.
I'd welcome any feedback either through this Blog or through the contact@cureality.com.
A conversation about vitamin K2 commonly leads to confusion. Several people have asked about something called nattokinase.
The scientific data on the potential role of vitamin K2 deficiency in causing both osteoporosis and vascular calcification is fascinating. Along with vitamin D3, vitamin K2 may be an important factor in regulation of calcium metabolism. Supplementation may prove to be a major strategy for inhibition of vascular calcification.
Obtaining K2 in the diet is tricky, since it's present in just a handful of foods: egg yolks, liver, traditional cheeses, and natto. This is where the confusion starts.
Natto is a Japanese fermented soy product. I've had it and it's quite disgusting. Nonetheless, Japanese who eat natto experience less fracture. (A parallel study in heart disease has not been performed.) Natto is also a source of another substance called nattokinase.
Advocates (otherwise often known as supplement distributors) claim that nattokinase is a "fibrinolytic", or blood clot-dissolving, preparation that "improves blood flow, protects from blood clots, and prevents heart attacks and strokes."
Don't you believe it. This is patent nonsense. There are several problems with this rationale:
--Any oral fibrinolytic agent is promptly degraded in the highly acid environment of the stomach. That's why all medically used fibrinolytics are given intravenously. Drug companies have struggled for years to encapsulate, modify, or somehow protect protein (or polypeptide) products taken orally from degrading this way. They've never succeeded. That's why, for instance, growth hormone (a polypeptide) remains an injection, not an oral agent. An oral growth hormone, by the way, would sell like mad, so the drug companies would very much like to figure out how to bypass the degradative effects of stomach acid. One of the "researchers" behind the nattokinase claims boasts that he has single-handedly figured out how to protect the nattokinase molecule in the gastrointestinal tract. However, he won't tell anybody how he does it. Right.
--Fibrinolytic agents are extremely dangerous. In years past, we used to treat heart attacks with intravenous fibrinolytic agents like tissue plasminogen activator, urokinase, streptokinase, and others. They have fallen by the wayside, for the most part, because of limited effectiveness and the unavoidable dangers of their use. Fibrinolytics are "dumb": they dissolve blood clots in both good places and bad. While they might dissolve the blood clot causing your heart attack, they also degrade the tiny clot in your cerebral (brain) circulation that was protective. That's why fatal brain hemorrhages, bleeding stomach ulcers, and blood oozing from strange places can also occur with fibrinolytic administration. Believe me, I've seen it happen, and I've watched people die from them.
The idea that a small dose taken orally is healthy is ridiculous. Even if nattokinase worked, why the heck would you take an agent that has known dangerous and very real consequences?
Don't let this idiocy reflect poorly on the K2 conversation, which, I believe, holds real merit and is backed by legitimate science. This is symptomatic of a larger difficulty with the supplement industry: Insane and unfounded claims about one supplement erodes credibility for the entire industry. It gives regulation-crazed people like the FDA ammunition to go after supplements, something none of us need. You and I have to sift through the nonsense to uncover the real gems in this rockpile, real gems like vitamin D3, omega-3 fatty acids from fish oil, and, perhaps, vitamin K2. But not nattokinase.
Here's a frequently neglected cause for an increasing CT heart scan score: High blood pressure with exercise. Let me explain.
Paul's blood pressure at rest, sitting in the office or on arising in the morning, or at other relatively peaceful moments: 110/75 to 130/80--all in the conventional normal range.
We put Paul on the treadmill for a stress test. At 10 mets of effort (on the protocol used, this means 3.4 mph treadmill speed at 14 degree incline), Paul's blood pressure skyrockets to 220/105. That's really high.
Now, blood pressure is expected to increase with exercise. If it doesn't rise, that's abnormal and may, in fact, be a sign of danger. Normally, blood pressure should rise gradually in a stepwise fashion with increasing levels of exercise. But any blood pressure exceeding 170/90 is clearly too high with exercise. (Not to be confused with high blood pressures not involving exercise.) A handful of studies have suggested that a "breakpoint" of 170/90 also predicts heightened risk of heart attack over a long period.)
I see this phenomenon frequently--normal blood pressure at rest, high with exercise. This also suggests that when Paul is stressed, upset, in traffic congestion, under pressure at work, etc., his blood pressure is high during those periods, as well. I wouldn't be surprised to see other phenomena of underappreciated high blood pressure, like abnormally thick heart muscle (left ventricular hypertrophy), an enlarged thoracic aorta (visible on your heart scan), left atrium, perhaps even an abnormal EKG or abnormal kidney function (evidenced by an elevated creatinine on a standard blood panel).
Unfortunately, the treatments that reduce blood pressure are "stupid," i.e., they have no appreciation for what you are doing and they reduce blood pressure all the time, whether or not you're stressed, exercising, or sleeping.
Blood pressure reduction should begin with weight loss, exercise, reduction of saturated fats and processed carbohydrates (esp. wheat), magnesium replacement, vitamin D replacement. Think about CoQ10. After this, blood pressure medication might be necessary.
The message: Watch out for the blood pressures when you have a stress test. Or, if you have a friend who is adept at getting blood pressures, get a blood pressure immediately upon ceasing exercise. It should be no higher than 170/90.
An interesting question came up on the Track Your Plaque Member Forum about vitamin D2 vs. vitamin D3. This often comes up among our patients, as well.
Vitamin D is measured in the blood as 25-OH-vitamin D and is distinct from 1,25-diOH-vitamin D, a kidney measure, a test you do not need unless you have kidney failure.
The human form of vitamin D is cholecalciferol and is usually obtained via activation of a precursor molecule in the skin on activation by the sun. You can also take cholecalciferol and it increases blood levels of 25-hydroxy vitamin D reliably.
However, there is a cheap, plant-sourced, alternative to vitamin D3, called vitamin D2, or ergocalciferol. D2 has far less effect in the body. Taking D2 or ergocalciferol orally is an extremely inefficient way to get D. Unfortunately, it's the form often used in milk and many supplements, even the prescription form of D. About half the multivitamins and calcium supplements I've looked at contain ergocalciferol rather than cholecalciferol.
Taking vitamin D2 yields very little conversion to the effective D3. This particular issues is maddening, as the USDA requires dairy farmers to add 100 units of vitamin D to milk, and D2 is often used. In other words, the D in many dairy products barely works at all. There are many children who rely on D from dairy products who are at risk for rickets and are not getting the D they need from dairy products because of this cost-saving switch. Do not rely on milk for vitamin D for your children.
D2 or ergocalciferol is often included in the blood measures of vitamin D along with vitamin D3. The only reason it's checked with blood work is to ensure "compliance,", i.e., see whether or not you're taking a prescribed ergocalciferol. Beyond this, it has no usefulness.
25-OH-vitamin D3, or cholecalciferol, is both the blood measure and the supplement you need. This is the one that packs all the punch. Keep in mind also that it is the oil-based gelcap you want, with more consistent and efficient absorption. Tablets usually barely work at all, even if it contains cholecalciferol. Most people who take calcium tablets with D, or multivitamin with D, not only are getting a powdered form of D, but also in trivial doses. It's the pure vitamin D3, cholecalciferol, in gelcap form you want if you desire all the spectacular benefits of vitamin D.
