Background and objective

Several studies have been conducted to examine the association between aldehyde dehydrogenase 2 family ALDH2 rs671 polymorphism and essential hypertension EH. However, the results remain inconsistent. This study aimed to clarify the association between ALDH2 rs671 polymorphism and EH susceptibility.

Methods

One thousand and ninety-four cases and 1236 controls who were ethnic Han Chinese were collected for this population-based case-control study. A meta-analysis was performed to calculate the pooled odds ratio and 95% confidence interval, using allele contrast, dominant, recessive, and co-dominant models using fixed or random-effect models.

Results

Significant differences were observed between EH cases and controls at the level of both genotype χ2 = 6.656, P<0.05 and alleles χ2 = 6.314, P<0.05. An additional meta-analysis using 4204 cases and 5435 controls established that rs671 was significantly associated with EH P<0.00001.

Conclusion

The results of our case-control study and meta-analysis showed that there is a significant association between ALDH2 rs671 polymorphism and EH susceptibility. In addition, the results of the breakdown analysis by gender suggest a male-specific association between the ALDH2 rs671 polymorphism and EH.
