Dr. Weeks’ Comment: High cholesterol is not the villain. Check out the International Association of Cholesterol Skeptics. If that assertion surprises you, read THIS and THIS and THIS. Inflammation is the main risk factor for sudden death from heart attacks and rarely is high cholesterol the problem. So read THIS and THIS and THIS and tell your doctor to take you and your loved ones off the statin drugs. (they steal your memory and give you muscle pain.) And did you know the cholesterol paradox? (i.e. the higher the cholesterol, the longer you live and that high cholesterol is PROTECTIVE if you have cancer.) Granted, any beneficial element like cholesterol once it is oxidized can be harmful. So ask your doctor to test these critically important blood tests to determine your REAL cardiac risk factors.
Anti-inflammatory cuts risk of heart attack
A clinical trial of more than 10,000 heart attack patients reported today supports a novel way to protect them from a stroke or a second attack: with drugs that stop inflammation. The approach has been advanced by some scientists for years, but this is the first trial to conclusively show that it works. Cardiologists hailed it as vindication for the heart attack-inflammation link, which hadn’t been proved in people.
The effect on future heart attacks is modest, but even skeptics were swayed. “I have to congratulate” those running this trial, says Terje Pedersen, a cardiologist at Oslo University who had been skeptical in the past.
Called the Canakinumab Anti-inflammatory Thrombosis Outcomes Study (CANTOS) and funded by the drug giant Novartis, the trial also found fewer cases of lung cancer in those on the treatment, rekindling basic research findings hinting that the same inflammatory pathway may initiate or spur the growth of such tumors. Nearly 2% of people in the placebo group were diagnosed with lung cancer during the study compared with 1% on the treatment. The actual disparity in number of cases between the two groups was small, with 129 lung cancers in all, and the trial wasn’t set up to study that disease.
CANTOS grew out of years of ups and downs in the heart disease field, as scientists tried to trace the role of inflammation, a complex cascade of immune signals and various white blood cells that occurs in response to wounds, infections, and more. One detective was cardiologist Peter Libby at Brigham and Women’s Hospital in Boston, who determined that various molecules recruit macrophages and other immune cells to blood vessels. That leads to inflammation and eventually, arterial plaques.
Back in the 1980s, when Libby’s work began, “I was a lonely voice” advocating a connection, he says. Now, researchers believe “the whole atherosclerosis process begins as an inflammatory event,” explains Mark Creager, director of the heart and vascular center at Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire, who wasn’t involved in the study. But was inflammation relevant to the triggering of actual heart attack””which often occurs when an arterial plaque ruptures and blocks an artery””not just the long process leading up to it? While Libby worked away in his lab, another cardiologist at Brigham and Women’s, Paul Ridker, began testing this premise in people. Ridker showed that high levels of inflammation molecules in a person’s blood can help predict a heart attack. One such marker is called c-reactive protein (CRP). In patients, Ridker found that statin drugs, widely known to prevent heart attacks by lowering cholesterol, lower CRP levels, too, suggesting they blunt inflammation””something Libby had seen in animals. But neither physician could promise that this anti-inflammatory power had anything to do with statins’ heart protection.
Meanwhile, results from these and other animal and observational studies appeared to clash with how anti-inflammatory drugs affected human hearts. In 2004, a large clinical trial of arthritis sufferers taking the nonsteroidal anti-inflammatory drug (NSAID) Vioxx for their condition were found to have double the normal risk of a heart attack, and the drug was yanked from the market. Steroids, which are potent anti-inflammatory drugs, also didn’t prevent heart attacks or strokes in people taking them for other reasons, several studies showed.
Ridker and Libby speculated that for an anti-inflammatory to work, it needed to be much more specific; NSAIDs and steroids have broad effects all over the body, and NSAIDs can spur inflammation along with blunting it. The pair focused on the monoclonal antibody canakinumab, already approved for juvenile arthritis, because it selectively targets a molecule called IL-1Î², which is part of the pathway driving atherosclerosis. Together, they persuaded Novartis to support a study.
The heart attack patients who enrolled all had high CRP levels and were given the best treatments available, including aggressive statin therapy. Half also received four infusions of canakinumab each year, at one of three different doses.
And in the end, those infusions made a difference, if a modest one. People receiving the placebo had about a 4.5% risk of a second cardiovascular event after a year versus 3.86% for those on the medium dose of the drug. This meant they were about 15% less likely to suffer a heart attack or stroke or die from cardiovascular disease. Over about 3.5 years, 535 of 3344 people in the placebo group suffered such an “event,” compared with 642 of 4547 getting the medium and high doses. Participants were also about 30% less likely to need a stent or cardiac bypass surgery if they got canakinumab, suggesting that damping down inflammation helps arteries stay healthy.
Ridker and others say that even a 15% reduction is exciting, because it came on top of the already significant benefits from the best standard treatment. They’re especially happy with the larger drop in invasive treatments. “I’m pinching myself,” Ridker says. This is “exactly what we had hoped for the last 30 years that we’d get. … It makes absolutely clear that if you lower inflammation, you lower risk.”
The results were presented this morning at the European Society of Cardiology meeting in Barcelona, Spain, with the heart data appearing simultaneously in The New England Journal of Medicine and the cancer analysis in The Lancet.
Where to go from here is complicated. For one, canakinumab is expensive, at about $16,000 per infusion…

NOTE from Dr. Weeks – now you know that the secret of cardiac health is to take anti-inflammatory agents which are safe and effective and cost-effective. Most over the counter anti-inflammatory agents are dangerous in that taking too many will destroy your liver or kidney. Meanwhile, most prescription agents are not only dangerous (steroid psychosis, joint destruction) but also ludicrously expensive ( see above $16,000 for a dose – come on!)
Just get your blood drawn for your levels of inflammation (inflammatory markers like hs-CRP, ESR, fibrinogen, homocysteine, IL-6, IL-8) and then eat the anti-inflammatory diet for 2 months and drink the anti-inflammatory seed drink for 2 months and RETEST your inflammatory markers and see what really works to prevent sudden death by heart attack.
