Brief summary

A large-scale, community-based, cross-sectional study was conducted to explore the extent to which genetic, environment and its interactions associated with cardiovascular autonomic neuropathy (CAN) in general Chinese population. A total of more than 2000 participants were recruited by using multiple stages sampling (first cluster sampling and then simply sampling). Data involved in variables of genetic, environment were collected. Every participants was complete DNA extracted and genotyped by using single nucleotide polymorphism (SNP). Cardiovascular autonomic functions were measured by using short-term heart rate variability (HRV) to evaluate the outcome of CAN. Genetic analysis were employed to evaluate genetic variants, environmental risk factors and its interactions for CAN.
