Large new clinical study launched to study. . .niacin


Oxford University has issued a press release announcing plans for a new clinical trial to raise HDL cholesterol and reduce heart attack risk. 20,000 participants will be enrolled in this substantial effort. The agent? Niacin.

How is that new? Well, this time niacin comes with a new spin.

Dr. Jane Armitage, formerly with the Heart Protection Study that showed that simvastatin (Zocor) reduced heart attack risk regardless of starting LDL, is lead investigator. She hopes to prove that niacin raises HDL cholesterol and thereby reduces heart attack risk. But, this time, niacin will be combined with an inhibitor of prostaglandins that blocks the notorious "flushing" effect of niacin.

The majority of Track Your Plaque participants hoping to control or reverse coronary plaque take niacin. Recall that niacin (vitamin B3)is an extremely effect agent that raises HDL, dramatically reduces small LDL, shifts HDL particles into the effective large fraction, reduces triglycerides and triglyceride-containing particles like IDL and VLDL. Several studies have shown that niacin dramatically reduces heart attack. The HATS Study showed that niacin combined with Zocor yielded an 85-90% reduction in heart attack risk and achieved regression of coronary plaque in many participants.

In our experience, approximately 1 in 20 people will really struggle using niacin. Flushes for these occasional people will be difficult or even intolerable. Should Dr. Armitage's study demonstrate that this new combination agent does provide advantages in minimizing the hot flush effect, that will be a boon for the occasional Track Your Plaque participant who finds conventional niacin intolerable.

But you already have access to niacin, an agent with an impressive track record even without this new study. And you have a reasonably effective prostaglandin inhibitor, as well: aspirin. Good old aspirin is very useful, particularly in the first few months of your niacin initiation to blunt the flush.

Although this study is likely to further popularize niacin and allow its broader use, it's also a method for the drug companies to profit from an agent they know works but is cheap and available.

You don't have to wait. You already have niacin and aspirin available to you.

    Niacin flushing can be effectively controlled with milk thistle. This information has been available for a year or so on www.nialor.com. I tried aspirin. It didn't work for me. Nialor is a product that combines 700 mg niacin with 175 mg of milk thistle powder. In my opinion, and this process worked for me, starting niacin should be done with small doses, such as 25mg with a milk thistle tablet once a day, then the combo twice a day, then 50 mg of niacin with a milk thistle tablet, etc., to gradually allow your body to adjust before taking the full Nialor tablet. In about two weeks, you should be able to take a Nialor tablet with 700 mg of niacin with its milk thistle and not flush. I now take three Nialor tablets a day, morning, noon and evening. It has been extremely effective for me. I initally tried niacin with aspirin. The flush was hard to take. Then I tried flush-free niacin. That did not produce a flush, but it was ineffective.

    Interesting ... did they lower their dose? Current informatiion shows only 500 mg crystalized niacin per tablet.

I don’t have high blood pressure!

I don’t have high blood pressure!

Art undeniably had high blood pressure.

At age 53, he had all the “footprints” of high blood pressure that’d been present for at least several years: abnormal patterns by EKG, abnormally thick heart muscle, and an enlarged aorta by an echocardiogram. These sorts of changes require many years to develop. Art’s blood pressure was 140/85 sitting quietly in the office.

“That’s about what my primary care doc gets, too. Whenever it’s high, he takes it again after a few minutes and it always comes down.”

Art tried to persuade me that his blood pressure was high today only because of the traffic on the way into the office. When I dismissed this as a cause, he insisted that stress he’d been suffering because of his teenage son was the cause. “I just know I don’t have high blood pressure!”




Who’s right here? Well, Art is not here to defend himself. But one fact is crystal clear: you cannot develop complications of high blood pressure unless you truly have high blood pressure!

In other words, Art’s abnormal changes in heart structure (thickened heart muscle and enlarged aorta) are serious changes that develop only with years and years of sustained blood pressure at least as high as the one in the office. His blood pressure almost certainly ranged much higher at other times, particularly during stressful situations like waiting in the check-out line at the grocery store, watching a suspenseful TV show, petty irritations at his job, and on and on.

Blood pressure does not have to be high all the time to generate complications of high blood pressure. It can be sporadic, variable, even occasional. Clearly, sustained high blood pressure is the worst situation that creates adverse consequences more quickly. But blood pressure that wavers from low to high only some of the time can still, given sufficient time, cause the very same unwanted effects.

Control of blood pressure is crucial to your coronary plaque control program. Blood pressure may be boring: not as exotic, say, as lipoproteins, and not as fun as talking about nutritional supplements. But neglect blood pressure issues and you will not gain full control over coronary plaque growth—-your heart scan score will increase.

Watch for an upcoming Special Report on the Track Your Plaque Membership website, a full detailed discussion of how to recognize when blood pressure is an important issue, along with a full discussion of nutritional methods to reduce it, often sufficient to minimize or eliminate the need for medication.

Tattered Red Dress

"Are you taking your health to heart? Perhaps you understand the importance of eating a diet low in cholesterol or getting 30 minutes of exercise a day. But do you know your own risk of developing cardiovascular disease?


It’s time to take your heart health personally. Heart disease is the No. 1 killer of American women — and that means it is not “someone else’s problem.” As a woman, it’s your problem.

That’s where the Go Red Heart Checkup comes in. This comprehensive evaluation of your overall heart health can help you now and in the future. By knowing your numbers and assessing your risks now, you can work with your doctor to significantly reduce your chances of getting heart disease tomorrow, next year, or 30 years from now!"



So reads some of the materials promoted by the American Heart Association Red Dress campaign to increase awareness of heart disease in women. The effort is well-intended. There is no doubt that most women are unaware of just how common coronary disease is in females.

But I've got a problem with the solutions offered. "Know your numbers"? Eat healthy, don't be overweight, be active, don't smoke. That's the gist of the program's message--nothing new. In 2006, why would some sort of screening effort for detectin of heart disease not be part of the message? Why isn't there any message about the real, truly effective means to detect hidden heart disease in women--namely, heart scanning?

Does a 58-year old woman with normal blood pressure, LDL 144, HDL 51, 20 lbs overweight have hidden heart disease? I've said it before and I'll say it again: You can't tell from the numbers. She could die of a heart attack tomorrow without warning, or maybe she'll be dancing on our graves when she's 95 and never have experienced any manifestation of heart disease. The numbers will not tell you this.

I'm glad the American Heart Association has seen fit to invest its sponsors' money in a campaign to promote prevention. I wish they hadn't fallen so far short of a truly helpful message. Perhaps the sponsors (like Pfizer, maker of Lipitor) will benefit, anyway.

Cath lab energy costs

Cath lab energy costs

In honor of Earth Day, I thought I'd highlight the unexpectedly high carbon costs of activities in hospitals, specifically the cardiac catheterization laboratory.

A patient enters the cath lab. The groin is shaved using a plastic disposable razor, the site cleaned with a plastic sponge, then the site draped with an 8 ft by 5 ft composite paper and plastic material (to replace the old-fashioned, reusable cloth drapes). A multitude of plastic supplies are loaded onto the utility table, including plastic sheaths to insert into the femoral artery (which comes equipped with a plastic inner cannula and plastic stopcock), a multi-stopcock manifold that allows selective entry or removal of fluids through the sheath, a plastic syringe to inject x-ray dye, plastic tubing to connect all the devices (total of about 5 feet), and multiple plastic catheters (3 for a standard diagnostic catheterization, more if unusual arterial anatomy is encountered).

All these various pieces come packed in elaborate plastic (polyethylene terephthalate or other polymers) containers, which also come encased in cardboard packaging.

Should angioplasty, stenting, or similar procedure be undertaken, then more catheters are required, such as the plastic "guide" catheters that contain a larger internal lumen to allow passage of angioplasty equipment. An additional quantity of tubing is added to the manifold and stopcock apparatus, as well as a plastic Tuohy-Borst valve to permit rapid entry and exit of various devices into the sheath.

Several new packages of cardboard and plastic are opened which contain the angioplasty balloon, packaging which is usually about 4 feet in length. The stent likewise comes packaged in an 18-inch or so long package with its own elaborate cardboard and plastic housing.

At the conclusion of the procedure, another cardboard/plastic package is opened, this one containing the closure device consisting of several pieces of plastic tubes and tabs.

If the procedure is complicated, the number of catheters and devices used can quickly multiply several-fold.

By the conclusion of the procedure, there are usually two large, industrial-sized trash bins packed full of cardboard, plastic packaging, and discarded tubing and catheters. The trash is so plentiful that it is emptied following each and every procedure. None of it is recycled, given the contamination with human body fluids.

That's just one procedure. The amount of trash generated by these procedures is staggering, much of it plastic. I don't know how much of the U.S.'s annual plastic trash burden of 62 billion pounds (source: EPA) originates from the the cath lab, but I suspect it is a big number in total.

So if you are truly interested in reducing your carbon footprint and doing your part to be "green," avoid a trip (or many) to the cath lab.

    Dr. Davis,
    Isn't a catheter used for an angiogram?  I thought an angiogram is a necessity before surgery for an aortic abdominal aneurysm?  What are the other alternatives if catheters make so much rubbish?  Just wondering since my mother is considering having surgery for her AAA and needs to have an angiogram first.
    Thanks,

    Dr. Davis doesn't answer questions posted to his blog any longer. He announced this some time ago.

    I think the point of his little story about being green is to avoid having to have such a procedure done in the first place. I don't believe he is suggesting that you ask the Hospital to recycle all the left over rubbish from such a procedure. At the rate of pay of those people, they'd probably have to charge you a couple of hundred dollars to sort everything out that could be recycled..  Frown

    I am only a lay person but I believe there is no alternative (less rubbish producing that is) to the procedure your Mom needs done. Don't worry about the trash and focus on your Mom's outcome instead.

    Good luck with your Mom's procedure.

    Catheter angiogram is no longer needed to demonstrate arteries, especially arterial anatomy in the abdomen, extremities,head and neck, including, carotids and intracerebral arteries, arteries in the arm or legs. There is now, an alternative, non-invasive. This consist of CT, CTA, or even better, without radiation an MRI,MRA. The only indication for catheter angiogram is if there is plan for angioplasty, or placement of a stent.
    No one or nobody should be subjected, to a catheter angiogram, in this day and age.
    I hope this helps.

    Dr. Davis,

    Much obliged for the post.  It provides me with a wonderful counter to claims that a grain-based diet has less of an environmental impact.

    Anonymous #2,
    Thanks for your comment about angiograms. I am still learning about this procedure and am glad to know that there may be other alternatives. My mom had no plans for a stent or an angioplasty but it seems that angiograms are the standard for elderly patients electing to fix AAAs. Anyway, lots of questions to ask the cardiologist when we see him again in a few weeks. Josephine

    Mmmm...stay out of the surgical ICU also, if you can help it. We generated on average 3-4 large cans of waste per room (14) per shift (12hr) per day. Efforts to separate out recyclables were futile. And let's not even get into hand washing. This was in 2000. I hope things have improved.
