For patients with both diabetes and atrial fibrillation (AF), how long someone has had diabetes is a better predictor of stroke than glycemic control of that patient.
Adding this metric to stroke risk models could provide more accurate stroke risk predictions. More than 2,000 patients enrolled in the Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) study were looked at. These patients had both diabetes as well as AF, and were put into two categories: those with diabetes for less than three years, and those who have had it for more than three years. The increase that corresponded with duration of diabetes was seen in both older and younger (older and younger than 75 years old) patients.
