  1. HPS: Heart Protection Study Purpose To determine whether simvastatin reduces mortality and vascular events in patients with and without coronary disease, but all at high risk, and with a broad range of baseline cholesterol levels Reference HPS Collaborative Group. MRC/BHF Heart Protection Study of cholesterol lowering with simvastatin in 20,536 high-risk individuals: a randomised placebo-controlled trial. Lancet 2002;360:7–22.

  2. HPS: Heart Protection Study - TRIAL DESIGN - Design Multicenter, randomized, double-blind, placebo-controlled Patients 20,536 patients aged 40–80 years, with and without coronary heart disease, but all at high risk, and with broad range of baseline total cholesterol: all >135mg/dL (>3.5mmol/L), mean 230 mg/dL (5.9 mmol/L) Follow up and primary endpoint Primary endpoint: all-cause mortality. Mean 5 years follow up. Treatment Placebo or simvastatin 40 mg daily

HPS Collaborative Group. Lancet 2002; 360 :7 Ð 22.

  4. HPS: Heart Protection Study- RESULTS - • All-cause mortality in simvastatin group significantly reduced compared with placebo (12.9 vs. 14.7%, P<0.0003); reduction was attributed largely to significant reduction in coronary death: • Other vascular death reduced but with marginal significance • Nonvascular death reduced but not significantly • First major vascular event rate significantly reduced, as were the individual event rates (fatal/nonfatal MI, fatal/nonfatal stroke, and revascularization) • No difference in new cancers (7.9 vs 7.8%, rate ratio 1.0, P=0.9) except nonmelanoma skin cancer (2.4 vs 2.0%) • No difference in withdrawal due to myopathy (0.5% in both groups)

  7. HPS: Heart Protection Study- SUMMARY - In high-risk patients with a broad range of baseline cholesterol values, simvastatin reduced: • All-cause mortality • Coronary deaths • Major vascular events
