• Abstract Background and Aims This study aimed to investigate the relationship between asymptomatic episodes of atrial fibrillation (AF) and abnormalities of the autonomic nervous system in type 2 diabetic patients who did not have evidence of atrial fibrillation at baseline. Methods and Results In a multicentric cross-sectional controlled study, 1992 patients with type 2 diabetes were screened. All underwent ambulatory ECG recording for 48-hour at 3, 6, 9, and 12 months. Heart rate variability (HRV) was used as indicator of autonomic activity. One hundred seventy-six diabetics with silent atrial fibrillation episodes (SAFE group) and 288 without silent atrial fibrillation (non-SAFE group) were enrolled. These selected diabetics were matched on clinical and anthropometric data to 120 control subjects without diabetes of the control group. HRV analysis evidenced that LF/HF ratio was significantly higher in the SAFE group than in the non-SAFE group (P < 0.05) in the whole period of HM analysis. AF absolute burdens were positively correlated with LF/HF ratio (r = 0.31, P < 0.001). Multiple regression analysis showed that LF/HF ratio was an independent determinant of AF episodes. Conclusions This study originally showed a strong relationship between autonomic dysfunction and silent atrial fibrillation in type 2 diabetes.
