How to reach LDL targets quickly in patients with diabetes or metabolic syndrome.
OBJECTIVE
To investigate whether using an algorithm to select the starting dose of a statin according to baseline and target LDL-cholesterol (LDL-C) values would facilitate achieving lipid targets in patients with diabetes or the metabolic syndrome.


METHODS
Two 12-week, prospective, open-label trials enrolled 2717 high-risk subjects, of whom 1024 had diabetes and 1251 had metabolic syndrome. Subjects with LDL-C between 100 and 220 mg/dL (2.6-5.7 mmol/L) were assigned a starting dose of atorvastatin (10, 20, 40, or 80 mg/d) based on LDL-C level and status of statin use at baseline (statin-free [SF] or statin-treated [ST]), with a single uptitration at 6 weeks, if required.


RESULTS
Among patients with diabetes, 81% of SF subjects (82%, 84%, 82%, and 76% with 10, 20, 40, and 80 mg, respectively) and 60% of ST subjects (61%, 68%, and 47% with 20, 40, and 80 mg, respectively) achieved LDL-C target. Among patients with metabolic syndrome, 78% of SF subjects (81%, 84%, 82%, and 66% with 10, 20, 40, and 80 mg, respectively) and 57% of ST subjects (58%, 70%, and 47% with 20, 40, and 80 mg, respectively) achieved LDL-C target. Among ST subjects, we observed reductions in LDL-C with atorvastatin beyond those achieved with other statins used at baseline in patients with diabetes and patients with metabolic syndrome. Atorvastatin was well tolerated.


CONCLUSIONS
The ACTFAST studies confirm that a targeted starting dose of atorvastatin allows most patients with type 2 diabetes or the metabolic syndrome to achieve their LDL-C target safely with the initial dose or just a single titration. This therapeutic strategy may help overcome the treatment gap still observed in the treatment of lipids in diabetes.
