Statin use in the secondary prevention of coronary heart disease in primary care: cohort study and comparison of inclusion and outcome with patients in randomised trials

I am puzzled by the title of the article, "Statin use in the
secondary prevention of coronary heart disease in primary care."
Secondary prevention refers to early detection of disease with a view to
minimizing morbidity and disability (see Last JM. A Dictionary of
Epidemiology, 4th ed. New York: Oxford University Press, 2001), but the
article describes the use of statins in tertiary prevention.
