Summary

Patients with diabetes have worse outcomes after percutaneous coronary intervention (PCI) procedures, compared to those patients without diabetes. They are at increased risk of death, heart attack, or needing further procedures due to renarrowing of their coronary narrowings after implantation of a coronary stent. Studies have suggested that poor control of diabetes may be partly responsible for these poor outcomes. Thiazolidinedione drugs, such as pioglitazone, can improve the diabetes control and make the patient more sensitive to the effects of insulin. Preliminary studies suggest that pioglitazone may also help prevent renarrowing after PCI.

This study was a pilot study designed to determine whether more aggressive treatment of the diabetes with the routine use of the drug pioglitazone (30mg/day for 6 months), in addition to the patient's usual diabetic medications adjusted to optimize their diabetic control (get glycated hemoglobin \< 7%), could reduce the amount of tissue buildup within the stent after 6 months, compared to a group less aggressively treated without pioglitazone and their usual medications for diabetes.

An intravascular ultrasound probe was used to assess the extent of tissue buildup within the stent and this was performed immediately after the PCI as a baseline and repeated after 6 months of therapy.

The investigators hypothesize that the more aggressive diabetic treatment with pioglitazone would reduce the extent of tissue growth within the stent after 6 months of therapy.
