On November 12, 2013, the American Heart Association (AHA) and the American College of Cardiology (ACC) disrupted the cardiovascular disease (CVD) universe by issuing four new guidelines. The guidelines depart from past efforts because the relevant federal agency, the National Heart, Lung, and Blood Institute (NHBLI), did not lead development. NHBLI now ‘sponsors’ guideline development, but has deferred actual writing and publication to private groups.
No word on when long-awaited companion blood pressure guidelines will emerge. If the blood pressure guidelines look anything like these cholesterol guidelines, then all rational arguments about cost containment will effectively come unhinged.
The guideline release was well orchestrated, not unexpected in organizations so well-funded by the pharmaceutical companies. They are the population that stands to benefit the most from what Alan Cassels, author of Selling Sickness and Seeking Sickness, which both seemed to anticipate moves like this, calls “statinization.” Fortunately, not everyone was drinking the “treatment today, treatment tomorrow, treatment forever” Kool-Aid; contrarian physicians believe that the guidelines simply lowered the therapeutic bar without clear evidence that doing so will improve outcomes, an ironic observation given that this is supposed to be about primary prevention.
The contrivance of simply altering a definition and having the subsequent area under the curve of healthy people who require treatment expand to include, oh, say 30 million more Americans is a merger-and-acquisition coup for pharma that would make Gordon Gekko blush.
Lowering the therapeutic bar will increase health care spending as physicians write more prescriptions and see more patients more often, certainly to monitor liver health, and probably for the side effects that cause double digit percentages of patients to stop and are routinely underreported in studies sponsored by the industry.
It also gives patients false security by promoting the belief that the heartily recommended drugs – statins – will provide a “cure,” a clinical get-out-of-jail-free card, which will surely diminish enthusiasm for lifestyle-based approaches to prevention that are free but unfortunately not reimbursable. And, as Abramson and Redberg note in their New York Times essay, the enunciated strategy will require perpetual treatment of 140 people to forestall 1 heart attack. Many of these people will now live long enough to experience “disease substitution,” allowing them to die of cancer or dementia.
The most important element of the new guidelines, however, is the shift away from pursuit of hard targets (get total cholesterol below 240 and LDL below 180) to a risk-based approach (for people without clinically evident disease), in which the therapeutic goal is to medicate non-diseased adults aged 40 to 75 who have an estimated 10 year risk of developing heart disease greater than 7.5% (down from 10% risk over 10 years). Overall, this necessary and overdue shift properly emphasizes CVD risk as a constellation and exposes our cultural tendency to seek or initiate treatment because of a single adverse attribute, which has led us to waste a fortune chasing clinical ghosts.
