<p><b>OBJECTIVE</b>To investigate the association of the 4G/5G polymorphism located in the promoter region of plasminogen activator inhibitor-1(PAI-1) gene with prognosis of coronary artery disease (CAD) in Chinese Hans.</p><p><b>METHODS</b>One hundred and fifty five patients with CAD and 190 unrelated healthy control individuals were included in the study. The 4G/5G polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. A follow-up survey of major adverse cardiovascular event (MACE) and analysis of the relationship between the severity of coronary vessels and PAI-1 gene polymorphism were carried out.</p><p><b>RESULTS</b>(1) The frequency of 4G/4G genotype of PAI-1 gene was higher in CAD patients than in controls (58/155, 37.42% vs 52/190, 27.37%, P< 0.01). (2) The frequency of 4G/4G genotype of PAI-1 in patients with MACE was higher than that in patients without MACE (40/81, 49.38% vs 18/74, 23.42%; P< 0.01). (3) The frequency of 4G/4G genotype in patients with multivessel disease was higher than that in patients with single-vessel disease (30/47, 44.77% vs 9/37, 24.32%; P< 0.05).</p><p><b>CONCLUSION</b>The 4G/5G polymorphism located in the promoter region of PAI-1 gene was associated with prognosis of CAD patients, and may be regarded as a biomarker of the severity of the involved vessels.</p>
