Polypill and the Future of Medicine
In 2003 in the
British Medical Journal, N.J. Wald and M. R. Law introduced a proposal
that they suggest could reduce all heart attacks by 88% and reduce all strokes
by 80%.1 Is this something that
would interest you? Is it something that should interest your doctors? The
proposed intervention was the use of something called the "Polypill" daily by
every one in the population over the age of 55 years without regard to their
health or regular medications. They also recommended it for all persons at high
risk of coronary artery disease regardless of their age.
The proposed "Polypill" consist of 6 ingredients that are
already in very widespread use. Two of the ingredients are, in fact,
over-the-counter products.
The 6 elements of the Polypill are:
aspirin (1 baby
aspirin, 81 mg)
folic acid (a vitamin, 0.8 mg)
a cholesterol-lowering medication known as a 'statin'
(like Lipitor)
hydrochlorothiazide (or HCTZ, a diuretic, 12.5 mg)
atenolol (a beta-blocker, 25 mg)
an ACE-inhibitor (e.g., enalapril, 5 mg)
The rationale for these agents
is very strong. Aspirin is already urged by the United States Preventive
Services Task Force as a routine preventive medication for the entire population
(at age 40 for men, and at the time of menopause for women). Folic acid is a
vitamin that is already recommended for all women of reproductive age to prevent
birth defects; and about half of adult diets in the U.S. are deficient in
intake. Statin medications are currently the most effective way to lower
cholesterol and are already recommended for any one at high risk of heart
disease. According to the 7th Report of the Joint National Commission on
Hypertension approximately 50% of the entire population aged 55 years who have
normal blood pressure are destined to become hypertensive. It has been
understood for many years that lowering the blood pressure of the entire
population by even 2-3 mm Hg would lead to a significant reduction in heart
attacks. So what these authors have done is to assemble several major trends in
cardiovascular health to identify the agents that could have the largest impact
on outcomes, and then subject these agents (i.e., the published trials that have
evaluated these agents) to rigorous analysis that led them to conclude that the
benefits of each individual class of medication would be additive since they
work in different ways.
Now, mind you, they have not done an actual study of these 6
ingredients used together in actual patients. They have merely analyzed the best
medical studies currently available on their use and efficacy and from these
have reached their conclusions. The Polypill proposal is at this time an
hypothesis, not a proven fact.
But why do you think it is
that you have never heard of it? That no one is using it? Or even talking to
patients about it? Could it be because hospitals, heart centers,
cardiologists and cardiac surgeons might lose up to 80% of their business? I'm
not sure. But I certainly believe this concept is important enough that everyone
should be talking about it and be evaluating its potential application to their
situation for themselves. Thus, as more information becomes available, I will be
providing updates here of how much of this promise is likely to be realized.
The good news is that, for the population of people already
identified as at high risk for heart disease, there are some actual clinical
data available which show that a combination of only 3 of the Polypill
ingredients led to an 83% reduction in heart attacks and death over a period of
5 years. This is startlingly close to the number predicted in the Polypill
hypothesis.
The bottom line is that this approach to disease prevention
deserves close watching in the years ahead, and we'll do that here.
And, as a final thought, what would happen if you combined this approach with a healthy lifestyle? Wouldn't that be something?
