To the Editor: Dr Nissen and colleagues1 reported coronary plaque regression as a result of high-dose statin therapy. In their “Comment” section, Figure 3 illustrates the relationship between achieved LDL-C levels and changes in plaque size using intravascular ultrasound, based on data from 3 randomized pharmacological intervention trials. It appears that an LDL-C value of 76 mg/dL was the cutoff at which the linear regression analysis predicted no plaque increase: the transition from progression to regression.
