| Heart failure rate high in people with diabetes
NEW YORK (Reuters Health) - The incidence of congestive heart failure
in patients with type 2 diabetes may be significantly higher than
previously estimated, new study results suggest.
The findings, presented at the American Diabetes Association's
meeting in Orlando this week, come from a review of medical records
and 6-year follow-up of more than 8,000 patients with type 2 diabetes
and a similar number non-diabetic matched "control" subjects.
Among those with diabetes, the incidence rate of heart failure
was equivalent to 30.9 case per 1,000 persons per year, 2.5 times
higher than the rate among non-diabetic controls.
Previous estimates of heart failure incidence in diabetic patients
range from between 2 and 10 cases per 1,000 persons per year. But
these were based on "smaller samples, shorter follow-up, or
cases requiring hospitalization," Dr. Gregory A. Nichols of
Kaiser Permanente in Portland, Oregon, and colleagues note in meeting
materials.
Analysis of the data showed that age, coronary heart disease, poorer
control of glucose levels, and greater body weight were "important
predictors" of the development of heart failure.
This study indicates that more people with type 2 diabetes are
developing heart failure than previously thought, and highlights
the importance of controlling risk factors for CHF such as obesity
and high blood sugar levels, Nichols team says.
