title: [Diabetic autonomic neuropathy diagnosed in primary care in patients with type 2 diabetes].
abstract: OBJECTIVE
  To determine the prevalence of diabetic autonomic neuropathy (DAN) in patients with type 2 diabetes using a cardiovascular test.
  
  
  METHODS
  Observational, descriptive, cross-sectional study.
  
  
  METHODS
  Primary care clinics in Fronteras de Torrejón de Ardoz Health Centre, Area 3, Madrid, Spain.
  
  
  METHODS
  Of the 361 diabetics assigned to 3 participating patient quotas, 317 patients had type 2 diabetes. Of those, 104 were excluded due to being immobile, cardiac arrhythmia, and/or on treatment with chronotropic drugs. Of the 213 patients included, 169 had the test and 44 were lost.
  
  
  METHODS
  Performing of the orthostatic response test.
  
  
  METHODS
  Age, sex, years since diagnosed with diabetes (measured by patient anamnesis), treatment (hygiene-diet measures, oral antidiabetics, insulin) were recorded, along with the R-R'30:15 ratio (classified as normal: 31.04, borderline: 1.01 to 1.03, and pathological: pound1.00).
  
  
  RESULTS
  The prevalence of DAN using the orthostatic response test was 56.2% (95 patients with a pathological R-R'30:15 index) out of a total of 169 patients with type 2 diabetes. The definitive diagnosis of DAN found in the clinical histories reviewed was 1.8%.
  
  
  CONCLUSIONS
  DAN goes unnoticed in our evaluation of the patient with diabetes. The improvement in diagnosing this complication and incorporating cardiovascular autonomic dysfunction tests in primary care follow-up protocols, would enable closer metabolic control and improve the prognosis of the disease.
