简要总结
This is a open-label, randomized, paired design, multicenter study of the Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System (R6000) for evaluating cardiovascular autonomic neuropathy. R6000 is novel intellectual diagnostic device for cardiovascular autonomic reflex tests and heart rate variability analysis. A total of 85 subjects will be enrolled in trial Ⅰ and 150 subjects will be enrolled in trial Ⅱ. In trial Ⅰ, subjects will be randomized to two groups, one of which will receive test by the tested device first and the other one will be tested by conventional blood pressure kit. The primary objective of this clinical trial is to evaluate the effectiveness of the Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System. The secondary objective is to evaluate the safety of the cardiovascular autonomic testing system and stability.
详细描述
Trial I Tested device: Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System (R6000). Control: Conventional blood pressure kit. Goal: To assess the consistency between the tested device and the conventional method in measuring blood pressure.
Trial IIa Tested device: Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System (R6000). Control: Ambulatory holter station. Goal: To assess the consistency between the tested device and the conventional devices in measuring heart rate variability (HRV).
Trial IIb Tested device: Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System (R6000). Control: Manual method with digital ECG machine, stethoscope and sphygmomanometer. Goal: To assess the consistency between the tested device and the manual method in determining cardiovascular autonomic neuropathy (CAN).

结局指标
主要结局
The diagnostic accuracy of the tested device versus manual method for the diagnosis of cardiovascular autonomic neuropathy (CAN).
时间窗: up to 6 months
Cohen's kappa coefficient will be used to assess the consistency between the tested device and the manual method in determining CAN status (positive or negative). The assessment will be conducted in part IIb.
次要结局
- The accuracy of the tested device versus conventional blood pressure kit with Korotkoff auscultatory technique for measuring blood pressure.(up to 6 months)
- The accuracy of the tested device versus the control device for measuring HRV.(up to 6 months)
