description <p><strong>Objectives</strong> The Heart Protection Study (HPS) provides an opportunity to assess directly the effects of cholesterol-lowering therapy on major vascular events (defined as myocardial infarction, coronary death, stroke, or revascularization) in patients with peripheral arterial disease (PAD). In addition, the effects on peripheral vascular events (ie, non-coronary revascularization, aneurysm repairs, major amputations or PAD deaths) can be assessed.</p> <p><strong>Methods</strong> 6748 UK adults with PAD and 13,788 other high-risk participants were randomly allocated to receive 40 mg simvastatin daily or matching placebo, yielding an average LDL cholesterol difference of 1.0 mmol/L (39 mg/dL) during a mean of 5 years.</p> <p><strong>Results</strong> For participants with PAD, allocation to simvastatin was associated with a highly significant 22% (95% CI 15-29) relative reduction in the rate of first major vascular event following randomisation (895 [26.4%] simvastatin-allocated vs 1101 [32.7%] placebo-allocated; P &lt; .0001), which was similar to that seen among the other high-risk participants. The absolute reduction in first major vascular event was 63 (SE 11) per 1000 patients with PAD and 50 (SE 7) per 1000 without pre-existing PAD. Overall, among all participants, there was a 16% (5-25) relative reduction in the rate of first peripheral vascular event following randomisation (479 [4.7%] simvastatin vs 561 [5.5%] placebo), largely irrespective of baseline LDL cholesterol and other factors. This effect chiefly reflects a 20% (8-31) relative reduction in non-coronary revascularization procedures (334 [3.3%] vs 415 [4.0%]; P = .002).</p> <p><strong>Conclusion</strong> HPS demonstrates the benefits of cholesterol-lowering statin therapy in patients with PAD, regardless of their presenting cholesterol levels and other presenting features. Allocation to 40 mg simvastatin daily reduces the rate of first major vascular events by about one-quarter, and that of peripheral vascular events by about one-sixth, with large absolute benefits seen in participants with PAD because of their high vascular risk. Consequently, statin therapy should be considered routinely for all patients with PAD.(J Vasc Surg 2007;45:645-54.)</p>
