BACKGROUND This study aimed to develop the artificial neural network (ANN) and multivariable logistic regression (LR) analyses for prediction modeling of cardiovascular autonomic (CA) dysfunction in the general population, and compare the prediction models using the two approaches. METHODS AND MATERIALS We analyzed a previous dataset based on a Chinese(More)
BACKGROUND The purpose of the present study was to evaluate the effect and predictive value of metabolic syndrome (MetS) and its components on diastolic heart failure (DHF) in patients at high risk for coronary artery disease (CAD). MATERIALS AND METHODS We enrolled 261 patients with normal left ventricular ejection fraction (≥50%) who were scheduled to(More)
BACKGROUND The present study aimed to develop an artificial neural network (ANN) based prediction model for cardiovascular autonomic (CA) dysfunction in the general population. METHODS We analyzed a previous dataset based on a population sample consisted of 2,092 individuals aged 30-80 years. The prediction models were derived from an exploratory set(More)
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(More)
BACKGROUND The purpose of this study was to evaluate the predictive value of DM and resting HR on CAN in a large sample derived from a Chinese population. MATERIALS AND METHODS We conducted a large-scale, population-based, cross-sectional study to explore the relationships of CAN with DM and resting HR. A total of 387 subjects were diagnosed with CAN in(More)
In this paper, we concentrate on WOM coding for writing equal-bit information twice (WOM2E). We studied the definition and coding solution of WOM2E. We encoded information via a codeword table and found that WOM2E achieved a better WOM-rate. However, the codeword table for large WOM2E cells is difficult to determine. We also introduced the coding sum rate(More)
Cardiovascular autonomic (CA) dysfunction has become a major health concern in China following rapid lifestyle changes [1,2]. Individuals with previously undiagnosed CA dysfunction have an unfavorable cardiovascular risk profile [3,4]. Delay and lack of detection of the disease mostly results from patients being asymptomatic during its early stages [5,6];(More)
