Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Several studies have investigated an association between cardiac autonomic neuropathy (CAN) and albuminuria, glomerular filtration rate, or both, and hypothesized that CAN is involved in the pathogenesis of nephropathy. However, most of these studies had focused on Caucasians and were limited to a small number of patients with type 1 diabetes mellitus, or had used a conventional Ewing battery of tests based on dynamic cardiovascular maneuvers.Yet, there is consistent data showing that Asian diabetic populations, including the Chinese, have a higher risk of renal complications than Caucasians do.

The present study investigated an association between heart rate variability (HRV) parameters and diabetic kidney disease (DKD) in Chinese type 2 diabetes mellitus (T2DM) patients, specifically through time and frequency domain analyses of HRV and urine albumin creatinine ratio (UACR) or estimated glomerular filtration rate (eGFR).

Type 2 diabetes

With Clinical examination and laboratory measurements

Clinical examination and laboratory measurements

Intervention Type OTHER

Subjects were interviewed by a physician regarding their medical history, history of hypoglycemic attacks, smoking status, and alcohol consumption. Concentrations of blood urea nitrogen (BUN) and serum creatinine (SCr) were analyzed by the urease-ultraviolet rate method and picric acid method, respectively. Serum uric acid was determined using the enzymatic colorimetric method. Serum hemoglobin A1c (HbA1c) was measured by liquid enzymatic assay. Urine albumin and urine creatinine were found through immune turbidimetric analysis and the enzymatic method, respectively.
