Statin Reduces Heart Attacks, Strokes, and Death in Healthy Older Adults, But at What Cost?
An article published today in the Los Angeles Times reported results of the JUPITER trial: Daily use of a specific statin drug in apparently healthy people reduced by 50% the chances of heart attack and stroke over two years. Furthermore, the odds of undergoing heart angioplasty or coronary artery bypass surgery were also reduced by 50%, and the odds of death by any cause were reduced by 20%.
The Jupiter trial enrolled men over 50 and women over 60 with normal cholesterol levels but elevated high-sensitivity C-reactive protein. The study was terminated after two years of follow-up. The study drug was rosuvastatin, manufactured by AstraZeneca and sold in the U.S. as Crestor at a cost of $3.45 per day (U.S.), according to the LA Times.
Do not assume that the drug’s beneficial effects demonstrated in JUPITER are a class effect applicable to all statin drugs such as Lipitor, Zocor, and Mevacor. If they are, let those drug manufacturers spend the time and money to prove it.
Critics of the study say that widespread similar use of statins in healthy middle-aged and older individuals would cost $9 billion a year in the U.S.
Who can wrap their brain around $9 billion a year? The recent U.S. Wall Street bail-out was $700 billion. The U.S. government just gave insurance company AIG another $40 billion. So $9 billion is chicken scratch, right?
Again according to the LA Times article, Dr. Mark Hlatky of Stanford University calculated the NNT - the number needed to treat - to prevent one heart attack, stroke or death over two years. That number is 120. In other words, to prevent one heart attack, stroke, or death over two years, 119 people have to take the drug daily for two years, with no benefit to them. At the outset of this preventive “treatment,” a given individual has less than a one percent chance of benefiting from treatment over the next two years.
At $3.45 per day, the drug costs $2,518 for two years. This doesn’t include the cost of physician visits and blood monitoring for toxicity. At the end of two years, what do you do? Your doctor is likely to recommend taking the drug indefinitely.
Does this sound like a good deal to you? Will you be that lucky one out of 120 to benefit? Can you think of better ways to spend your $2,518 over the next two years?
Would you consider other ways to prevent heart attack, stroke, and death, such as losing excess weight, quitting smoking, getting regular exercise, and switching to a traditional Mediterranean diet?
Popping a pill is easier, no doubt.
Let’s say you decided to spend your $2,518 on something other than Crestor. But your health insurance will pay for it. Would you take the pill then?
Remember, AstraZeneca isn’t going to give the drug away for free. They’ve spent millions on development and testing. Someone has to pay for it, whether it’s you, your health insurer, or your employer. If the latter two pay, won’t that be reflected in higher insurance premiums or lower paychecks?

Good analysis
I heard a well known physician say that every adult should take a statin.
It is certainly true that most of the studies have been positive.
However, I tend to think whatever comes up must come down. In other words, when everyone starts taking it, we will start hearing about side effects and lawsuits. We already know about the risk of rhabdomyolysis (muscle damage).
I think you have to start with healthy diet and exercise. Unfortunately a lot of people want the quick fix.
Having said that, I would take a statin if my LDL Cholesterol, or CRP is high, after trying the diet and exercise.
Thanks for the info

Thanks for your comments, Dr. Hubbard. In the JUPITER study, overall side effects were relatively low, and the study authors thought them quite acceptable in view of the potential benefits.

I’d like to see the Mediterranean diet (ala Lyon Diet Heart protocol) go head-to-head with statins. Here’s why.
First, consider some of the ways that statins work:
• Prevents the potent omega-6 fat, arachidonic acid release from the LDL-cholesterol. Arachidonic acid increases blood clots, arrhythmias and stiffens arteries. Arachidonic acid, produces several powerful inflammation that impact cardiovascular health.
• Statins also prevent the formation of isoprenoids, another potent group of inflammatory compounds, which are derived from Arachidonic acid.
While this might sound like I’m making the case for statins, to the contrary—it’s another reason to eat a Mediterranean diet, which is low in omega-6 fat and high in omega-3 fats. When you lower omega-6 fats, you lower the fuel for inflammation. The higher dietary DHA and EPA (from fish) displaces arachidonic acid from the cell membranes, reducing inflammation further. Let’s also not forget the recent trial where fish oil out-performed statins in patients with chronic heart failure.
Lastly, there is compelling evidence from Lyon Diet Heart Trial, which compared eating a Mediterranean-style diet the standard diet recommended by the American Heart Association. After four years on this diet, participants experienced a reduction in all causes of death, including heart disease. The impact of this diet was also reflected in blood phospholipids, with a lower ratio of omega-6 to omega-3 fats. The classic cardiac diet does not distinguish between the types of polyunsaturated fat, which is mostly omega-6 fat and failed to improve the overall prognosis.

Wow.
Cogent analysis, as usual, Evelyn. Thanks.
