ANCHOR LEAD: TIGHT BLOOD SUGAR CONTROL MAY NOT HELP AVOID HEART DISEASE IN PEOPLE WITH DIABETES, ELIZABETH TRACEY REPORTS
Keeping blood sugar under tight control is known to help avoid complications of diabetes like eye and nerve problems, but the most recent large study seemed to conclude that it doesn’t help heart disease. Sherita Golden, a diabetes expert at Johns Hopkins, says trying to keep the best measure of blood sugar control, hemoglobin A1c, under 7%, wasn’t beneficial.
GOLDEN: That was very surprising. The question was should the target be less than 7% for the prevention of heart disease, as the target currently is for preventing small vessel disease, and turns out that in three of those studies there was no benefit to tight glucose control in preventing heart disease, and in fact in one of those studies there was a higher mortality in the intensive group, so I think its going to be really important to evaluate those data and follow up, and still ask the question are there subgroups that may benefit? But at least in the populations that they studied, it didn’t seem like there was a benefit and that was quite surprising. :32
Golden says more study is still needed. I’m Elizabeth Tracey reporting.
