Abstract

Background: Epidemiological studies support the role for a strong genetic component in the occurrence of early-onset myocardial infarction (MI), although the specific genetic variants responsible for familial clustering remain largely unknown. Methods: The Italian study of early-onset MI is a nationwide case-control study involving 1864 case patients C [(rs662799), minor allele frequency 0.084 (95% confidence interval (CI) 0.07-0.09)] alone showed a statistically significant association with risk of early-onset MI (p=6.7×10-5), after Bonferroni correction, with a per C allele odds ratio of 1.44 (95% CI 1.23-1.69). In controls, APOA5-1131T>C was significantly associated with raised plasma triglyceride levels (p=0.001), compared with non-carriers, the per C allele increase being 11.4% (95% CI 4-19%), equivalent to 0.15mmol/L (95% CI 0.11-0.20mmol/L). In cases, the association with early MI risk remained statistically significant after adjustment for triglycerides (p=0.006). Conclusions: The APOA5-1131C allele, associated with higher fasting triglyceride levels, strongly affects the risk for early-onset MI, even after adjusting for triglycerides. This raises the possibility that APOA5-1131T>C may affect the risk of early MI over and above effects mediated by triglycerides.
