How much longer will you live if you take a statin?


"Looking at the Heart Protection Study (HPS) done in the UK, we used a technique for analysing survival time called RMST (restricted mean survival time). I won’t go into the details. The HPS study lasted for five years, and we calculated that the average increase in survival time was 15.6 days. This was at the end of five years of treatment (with a confidence interval of 5 days either side). For 4S, the figure was 17 days."

"Framing this slightly differently, what this meant was that taking a statin for one year, in the highest risk group possible, would increase your life expectancy by around three days."

"However, more recently the BMJ did decided to publish another paper entitled: ‘The effect of statins on average survival in randomised trials, an analysis of end point postponement.

Results: 6 studies for primary prevention and 5 for secondary prevention with a follow-up between 2.0 and 6.1 years were identified. Death was postponed between −5 and 19 days in primary prevention trials and between −10 and 27 days in secondary prevention trials. The median postponement of death for primary and secondary prevention trials were 3.2 and 4.1 days, respectively."

Conclusions: Statin treatment results in a surprisingly small average gain in overall survival within the trials’ running time. For patients whose life expectancy is limited or who have adverse effects of treatment, withholding statin therapy should be considered
Overall their findings were far less impressive, even, than ours. They calculated, approximately, a single day of increase in life expectancy for each year of taking a statin. Slightly more in secondary prevention, slightly less in primary (people who have not previously had a heart attack or a stroke).
The main take away message I believe, is the following. Statins do not prevent fatal heart attacks and strokes. They can only delay them. They delay them by about one or two days per year of treatment. For those who have read my books you will know that I have regularly suggested we get rid of the concept of ‘preventative medicine’. We need to replace it with the concept of ‘delayative medicine’.
