This study, which lasted for 6 years, was designed to determine whether pravastatin compared with patients usual medical care, reduces death rates in patients aged 55 or older who have high cholesterol and blood pressure and other heart disease risk factors. 10,355 participants were enrolled in the study and were assigned into 2 groups where they received either 40 mg of pravastatin a day or their usual medical care.

The researchers found at the end of the 6 year study:
(a) Heart disease death rates were virtually identical in both groups.
(b) Those who took statins had an 11% increased risk of death from cancer compared to those who did not take statins.
(c) Those who took statins had an 7% increased risk of suicide/homocide/accidental death compared to those who did not take statins.

The results of this study suggest that statin treatment increases the risk of death from cancer.
