Lifestyle modification is the cornerstone of preventing atherosclerotic cardiovascular disease. When this is not sufficient in reducing risk, statin therapy is first line. Heart Outcomes Prevention Evaluation (HOPE-3) was a randomized controlled trial of rosuvastatin versus placebo, which demonstrated a significant net benefit in a lower-risk population without known atherosclerotic cardiovascular disease. There were many novel characteristics about this trial that should not be overlooked. It contained a diverse population and was the first trial to base inclusion solely on easily ascertainable metabolic risk factors. It had high adherence in the statin arm, likely due to several factors, including a run-in phase, close follow-up, and low intolerance of moderate-dose rosuvastatin. Attempting to simulate these could increase adherence among clinic populations. Although HOPE-3 did not demonstrate a significant decrease in cardiovascular events among women, meta-analysis including prior randomized controlled trials still demonstrates significant benefit, supporting prior guidelines for statin therapy in this group. Finally, HOPE-3 provides data that potentially support the legacy effect of statins. Understanding these key points provides additional insight into the benefits of statin therapy.
