To the Editor: The IDEAL study1 is 1 of 4 recent large clinical trials that have examined whether high-dose statins improve outcomes compared with conventional doses. The first 2 trials (PROVE-IT2 and A to Z3) enrolled patients with acute coronary syndromes (ACS), whereas the latter 2 trials (TNT4 and IDEAL1) enrolled patients with stable coronary artery disease. The results from these trials appear to conflict: PROVE-IT and TNT found statistically significant differences, whereas A-to-Z and IDEAL did not. Some of these conflicts may be related to the study designs.
