Bayesian estimation of cardiovascular autonomic neuropathy diagnostic test based on short-term heart rate variability without a gold standard.

ABSTRACT:

Objective

To evaluate the reference values for short-term heart rate variability (HRV), estimate the performance of cardiovascular autonomic neuropathy (CAN) diagnostic tests in the absence of a gold standard, and assess CAN prevalence in our dataset.

Setting

Community and hospital health centre.

Participants

Of 2092 subjects available for data analysis, 371 healthy subjects were selected so the reference values for the short-term HRV test could be evaluated. An external dataset contained 88 subjects who completed both the short-term HRV test and Ewing's test.

Intervention

Collection of information on clinical outcome.

Primary and second outcome measures

Cardiovascular autonomic function evaluated by using the short-term HRV test and/or Ewing's test.
