To test whether 5 years of pravastatin treatment leads to a reduction in MI>

Study design
Randomised, double-blind, placebo-controlled

5 years (mean 4.9 years)

6595 men, aged 45-64 years, with LDL cholesterol ≥ 4.0 and ≤ 6.0 mmol/l and no history of MI

Treatment regimen
Pravastatin, 40 mg each evening, or placebo

Concomitant therapy
Smoking and dietary advice during the whole study

Pravastatin lowered plasma cholesterol levels by 20% and LDL cholesterol by 26% whereas there was no change with placebo. There were 248 definite coronary events (nonfatal MI or death from coronary heart disease) in the placebo group and 174 in the pravastatin group (relative risk reduction with pravastatin 31%; p < 0.001). There were similar risk reductions with pravastatin for nonfatal MI (31% reduction; p < 0.001), death from coronary heart disease (33% reduction; p = 0.042) and death from all cardiovascular causes (32% reduction; p = 0.033). There was no excess of deaths in the pravastatin group, and the risk of death from any cause was reduced by 22% in the pravastatin group (p = 0.051)
