Conclusion

High-dose pitavastatin therapy significantly reduced CV events and overall mortality in Japanese patients with stable CAD compared with low-dose pitavastatin therapy. This study supports that administration of higher doses of statins, within the range of local approval, is the preferred statin therapy in Japanese patients with established CAD, regardless of their baseline LDL-C levels.

*Discussion*

Discussant Karol Watson (UCLA, Los Angeles, CA, US) stated that this trial has provided information on the treatment of Asian CAD patients with high-dose statin. She expressed her surprise that also a mortality benefit was seen. All patients first received 1 mg daily, and after randomization LDL-c further reduced in those assigned to 4 mg. Importantly, treatment was very well treated.

She did raise the following points that are still unknown. Would outcomes have been improved with greater LDL-c reduction? She pointed out that the dose of 4 mg pitavastatin that was used in this study is considered a moderate-intensity statin therapy that results on average in a lowering of ~30% to <50%. It would be interesting to examine the effect of high-intensity statin therapy (> 50% LDL-c reduction) as recommended by the 2013 AHA-ACC cholesterol guidelines. However, would high intensity statin therapy be well tolerated in an Asian population? Concerns have been raised that Asians might tolerate high-intensity statins less well. In addition, Prof. Watson wondered whether these data translate to other statins, and what happened to the participants lost to follow-up?

Overall, this trial has demonstrated that high-dose statin strategy in Asian patients is safe, well tolerated and beneficial.
