Impact of ALDH2 Gene Polymorphism on Coronary Artery lesions in Ethnic Hakka Population with Acute Myocardial Infarction
Abstract Background: Aldehyde dehydrogenase 2 (ALDH2) contributes to converting acetaldehyde into acetate, thus plays a key role in the ethanol metabolism and oxidation of acetaldehyde. The aim of this study is to investigate the impact of Aldehyde dehydrogenase 2 (ALDH2) gene polymorphism on coronary artery lesions in ethnic Hakka patients with acute myocardial infarction (AMI). Methods: A total of 312 patients (male = 241, female = 71) with acute myocardial infarction (AMI) suffered ≥ 50% stenosis of at least one major coronary artery were recruited into the study. Lesions of AMI patients carried different ALDH2 genotypes were analyzed. Results: The incidence of multivessel lesions was higher in the ALDH2 mutation group (90.6%) than the ALDH2 wild group (80.3%) with reaching statistical significance (p = 0.009). Compare to the single lesion group, multivessel lesions group were more likely to be lower DBP (77.3 ± 14.1 versus 86.4 ± 13.8, p = 0.004), older (66.1 ± 12.2 versus 59 ± 12.1, p = 0.009), have hypertension (55.7% versus 30.8%, p = 0.023) in the ALDH2 wild patients. In the ALDH2 mutation patients, multivessel lesions group also tend to be elderly (65.9 ± 11.3 versus 58.5 ± 11.3, p = 0.011). In the addition, the multivessel lesions group presented higher levels of the TG and lower levels of the LDL-C than the single lesion group, but it is no statistical differences. The logistics regression showed that age and ALDH2 mutation were vulnerable to the multivessel lesions the ethnic Hakka population with AMI. Conclusions: The AMI patients in ethnic Hakka population carrying mutated ALDH2 allele was vulnerable to multiple coronary artery lesions. ALDH2 allele was associated with multiple coronary artery lesions in AMI patients among ethnic Hakka population. Key words: ALDH2 mutated allele, coronary artery lesions, acute myocardial infarction
