Amulticenter European study found that blood sugar control may help patients with type 2 diabetes following a heart attack. Intensive insulin therapy, however, does not appear necessary to achieve better outcomes. The study analyzed 3 glucose-control strategies2 insulin-based and 1 based on standard practiceto treat >1200 patients with diabetes after they had a suspected heart attack.
The results of the study indicated lower blood glucose levels with the 2 insulin therapies within 24 hours. Yet, glucose control over a period of time did not differ among the 3 treatment approaches. The mortality rate also did not change among all the treatment groups. The researchers said that what did have an impact was the blood sugar level, with high glucose levels being "one of the most important prognostic predictors"of a patient's death. (The findings were published in the European Heart Journal, April 2005.)
