Objective: To investigate the relationship between matrix metalloproteinase (MMP) 1 gene -519A/G polymorphism and the risk of coronary heart disease (CHD) in Northern Chinese Han population.
Methods: A total of 517 patients with CHD and 380 healthy adults diagnosed by coronary angiography were genotyped by polymerase chain reaction-restriction fragment length polymorphism and DNA sequence technology for the -519A/G polymorphism in MMP1 gene.
Results: (1) The frequency of AA genotype was significantly higher in patients with CHD than that in controls [67.
