Cardiovascular disease

To test whether pravastatin reduces the risk of vascular events in elderly people with pre-existing vascular disease or at high risk of its development

Study design
Randomised, double-blind, placebo-controlled

Mean 3.2 years

5804 individuals (2891 pravastatin, 2913 placebo), mean age 75 years, with either pre-existing vascular disease or raised risk due to smoking, hypertension or diabetes, and with total cholesterol 4.0–9.0 mmol/l and triglycerides < 6.0 mmol/l

Treatment regimen
Pravastatin, 40 mg/day, or placebo

Concomitant therapy
Diet to provide < 30% of total calories from fat (< 10% as saturated fat) and cholesterol intake of < 300 mg/day

Pravastatin reduced the incidence of the primary composite endpoint of death from coronary heart disease, nonfatal MI and fatal or nonfatal stroke to 14.1% compared to 16.2% with placebo (hazard ratio 0.85, 95% CI 0.74–0.97; p = 0.014)
