The median of Lp(a) was 113 mg/l in whole population, 108 mg/l in non-CAD and 134.5 mg/l in AMI groups, which was consistent with the result from Sun et al.’s Study [5], higher than that in Cui FM’s study (median value 56 mg/l) [19], but significantly lower than that in other ethnic populations [20,21]. This evidence concerns the gene LPA and coronary artery disorder.
