The association between vesicle-associated membrane protein-8 A/G gene polymorphism and the risk of acute myocardial infarction

Introduction: Until now, only few studies have reported the correlation between vesicle-associated membrane protein-8 (VAMP-8) A/G gene polymorphism and acute myocardial infarction. Whereas, theoretically, VAMP-8 plays a pivotal role in the pathogenesis of acute myocardial infarction through platelet activation, secretion, and aggregation. Objective: To investigate the association between VAMP-8 A/G gene polymorphism and the risk of acute myocardial infarction. Methods: A cross-sectional study was carried out at Saiful Anwar General Hospital during June 2013-May 2014. A Mae II enzyme with restriction fragment length polymorphism method was used to genotype VAMP-8 A/G gene polymorphisms in acute myocardial infarction and control groups. A multiple logistic regression test was used to analyze the association between VAMP-8 A/G gene polymorphism and the risk of acute myocardial infarction. Results: A total of 35 controls and 97 acute myocardial infarction patients from our Hospital during the period were enrolled for our study. Our results found that VAMP-8 A/G gene polymorphism was not associated with the risk of acute myocardial infarction. Moreover, we also failed to confer the association between VAMP-8 A/G gene polymorphism and both smoking and hypertension among patients with acute myocardial infarction. Furthermore, in the setting of premature acute myocardial infarction, the correlation also failed to confirm. Conclusion: In our population, there is no association between VAMP-8 A/G gene polymorphism and the risk of acute myocardial infarction.
