摘      要：Background Hypertension （HTN） is a major determinant of various cardiovascular events. Plasma levels of plasminogen activator inhibitor 1 （PAl-l） modulate this risk. A deletion/insertion polymorphism within the PAl-1 loci （4G/4G, 4G/5G, 5G/5G） affects the expression of this gene. The present study investigated the association between PAl-1 loci polymorphisms and HTN in Korean women. Methods Korean women （n=1312） were enrolled in this study to evaluate the association between PAl-1 4G/5G gene polymorphisms and HTN as well as other metabolic risk factors. PAl-1 loci polymorphisms were investigated using polymerase chain reaction amplification and single-strand conformation polymorphism analysis. Results The three genotype groups differed with respect to systolic blood pressure （P=0.043）, and diastolic blood pressure （P=0.009） but not with respect to age, body mass index, total cholesterol, low or high density lipoprotein cholesterol, triglycerides, or fasting blood glucose. Carriers of the PAl-1 4G allele had more hypertension significantly （PAl-1 4G/5G vs. PAl-1 5G/5G, P=0.032; PAl-1 4G/4G vs. PAl-1 5G/5G, P=0.034）. When stratified according to PAl-1 4G/5G polymorphism, there was no significant difference in all metabolic parameters among PAl-1 genotype groups in patients with HTN as well as subjects with normal blood pressure. The estimated odds ratio of the 4G/4G genotype and 4G/5G for HTN was 1.7 （P=0.005）, and 1.6 （P=0.015）, respectively. Conclusion These findings might indicate that PAl-1 loci polymorphisms independently contribute to HTN and that gene-environmental interaction may be not associated in Korean women.
