Lows Are Linked to Heart Attack Risk


Dangerously low blood glucose levels may spell heart trouble for people with type 2 diabetes. Researchers analyzed six studies involving more than 903,000 people with type 2 diabetes and found that up to 5.8 percent of them had experienced severe hypoglycemia—in which they required assistance to treat low blood glucose—during one- to five-year follow-up periods. Severe hypoglycemia was strongly associated with an increased risk of cardiovascular disease, including heart attack and stroke. Previous studies have suggested the link stems from other illnesses participants may have, but the authors of this study said that was unlikely. The researchers suggested that looser blood glucose targets be considered for people with type 2 who are at high risk for hypoglycemia.
