More good news for metformin. MET-REMODEL trial tested patients with known cardiovascular disease and insulin resistance, but without gross diabetes. Patients received metformin or placebo for 12 months.
Compared to the placebo group, subjects receiving metformin experienced the following improvements in 12 months: Less left ventricular mass index, less LVM, lower systolic BP, decreased body weight and less oxidative stress.
Early start of metformin could be useful in adults with insulin resistance. Long term side effects of metformin, however, need to be discussed thoroughly with patients.
