A simple, inexpensive treatment for myocardial infarction (MI) that was abandoned more than 20 years ago may deserve a second chance.
The treatment under study is a combination of glucose, insulin, and potassium (GIK). The combination first was reported as a promising treatment for MI in 1962. Some physicians used it for nearly a decade but ceased when clinical studies offered no consensus on its effectiveness. But now a pilot study of MI patients in South America and Mexico indicates that GIK reduces MI mortality.
