Could we predict asymptomatic cardiovascular autonomic neuropathy in type 1 diabetic patients attending out-patients clinics?
GROUND AND AIMS: Diabetic cardiovascular autonomic neuropathy (CAN) is associated with increased morbidity and mortality. This complication may be asymptomatic for a long time. The aim of this study was to assess the prevalence, severity and predictors of asymptomatic CAN in patients with type 1 diabetes mellitus (DM1). PATIENTS AND METHODS: 107 patients with DM1 were enrolled: 52 men and 55 women aged 39.8 +/- 12.4 years (18-72), duration of DM 16.6 +/- 9.5 years (0.5-43), age at DM manifestation 23.5 +/- 12.8 years (1-54) and BMI 25.1 +/- 3.2 (18.9-33.91). CAN was assessed using standard cardiovascular reflex tests (Ewing battery) and the patients were divided into three groups according to the results: Group 0, without CAN; Group I, 1(st) degree CAN; Group II, 2(nd) degree CAN. We assessed the most frequent relationships between CAN and chronic complications, episodes of severe hypoglycemia, time-related parameters (age of patients, duration of diabetes, age at manifestation), glyco
