I am greatly concerned with the new statin guidelines recently released by the American Heart Association and the American College of Cardiology during the yearly Scientific Sessions held in Dallas this November. Guidelines introduced to the public with great fanfare, and covered by all National media outlets.
These guidelines take healthy people and input certain risk factors that include age, body weight, smoking history, family history of heart disease, blood pressure and cholesterol levels to determine future cardiovascular (CV) risk. Those that are found to have a CV risk of 7.5% or greater, in the following 10 years would be candidates for statins. (Statins were first introduced in 1987, and over the years, their use has increased. The annual expenditure in 2000 on statins: $7.7 trillion, by 2007: $20 billion). These medications help reduce the amount of cholesterol and LDL (so-called bad cholesterol) in the blood. It is believed however, that statins work in decreasing heart disease because they decrease the degree of inflammation. An effect is given the name pleotrophic effect.
Under the new guidelines, an additional 31 million people would meet criteria for these drugs. Currently, about 15% of all adults in the U.S. take statins and the new guidelines would double it to around 33%. Generalizing treatment to a wide cross section is of concern, because the likelihood of success or failure of a treatment is not identical in all individuals treated, because therapy is not the only determinant of outcome.
It is this continued reliance and focus on drugs that concerns me. I am also concerned and confused with the frequent changes, recommendations and mixed messages made by the medical establishment. How often do we read a medical “expert” recommending one thing, only to have another “expert” recommend something completely opposite, contraindicating the first expert? In a country with so many “experts,” it’s no wonder why patients (myself included) don’t know who or what to believe.
Are we really so sure we should proceed to double the number of U.S. adults on statins as suggested by the new guidelines? Can we be so sure that the benefits of this class of medicines outweigh the risks? We know that the use of statins short-term has side effects in some patients, but what happens after 10 or 20 years of use?
Cholesterol is not a villain. The absorption of vitamins and minerals including vitamin D, is dependent on cholesterol, which is why our bodies produce it. Multiple studies have shown that statin users have higher rates of cataract formation, increased muscle pains, increased musculoskeletal injuries, reduced blood levels of vitamin D, reduced levels of CoQ10, just to name a few side effects. Most importantly, statins may worsen and possibly cause diabetes. Nevertheless, in one of the ironies we have come to expect from modern medicine, the new AHA/ACC statin guidelines recommend statins for most diabetics.
I have nothing against statins. As a cardiologist, I prescribe statins when needed. What I am against is the indiscriminate use and abuse of not just statins but of all medications and an ever-increasing reliance of medications for everything that ails us.
I will continue to use statins as I do presently. In men younger than 75 years with coronary heart disease, including acute coronary syndrome, chest pain (angina), in those who have had heart surgery (bypass) or stents. People with hereditary hypercholesterolemia should also be considered for statin use. These are the groups that have been shown to get the most benefit from this class of drug. Their use in diabetic women and people with strokes (although current indications) is controversial.
Studies have shown that there is no reason or benefit for the elderly to be on long-term statin treatment. Low cholesterol levels in people over the age of 75, has been associated with decreased cognitive function. Maybe it’s because 25-30% of our brain is made up of cholesterol and cholesterol is essential for many metabolic functions including the production of hormones. However, there are even other medical “experts” who have suggested that it would be a good idea to start giving statins to children.
I find the reliance on medications that have potent side effects to be ongoing failure of the U.S. healthcare system, the costliest healthcare system in the world that only manages a quality and efficiency ranking of 46, behind Iran and ahead of Serbia. It is time to end the “pill for every ill” mentality of disease care synonymous with U.S. health care and make a radical shift back to using common sense and reasoning.
Instead of prescribing more drugs, we should be educating and stressing to the general public the importance and need for lifestyle and nutritional change first. The same inflammation and conditions that causes the elevated cholesterol levels that is treated with statins, are caused by and therefore can also be limited and controlled by diet and improved nutrition.
I find it interesting that the dietary advice of 40 years ago, which stressed the importance of eating minimally processed foods, avoidance of artificial sweeteners, selection of meats from organically raised animals and not industrially produced variety, went directly against the recommendations of the experts of that time.
I’ll continue to individualize treatment, educating my patients on the importance of food, exercise and lifestyle and prescribing drugs only when appropriate. I doubt future studies will find anything contradictory with this approach.
