Abstract:
Objective The relationship among angiotensin converting enzyme(ACE) gene polymorphism,angiotensin converting enzyme activity and coronary heart disease(CHD) was studied.Method Teh polymerase chain reaction was used to detect an insertion/deletion(I/D) of ACE gene polymorphism in the sixteen intron,then genotype and allele freqencies were counted .The method of enzyme coupling ratio was used to detect ACE activity .Results In 51 case with CHD ,the DD genotype and D allele freqencies of ACE gene were 35% and 61% respectively ,ACE average activity was (350 3?91 1)su/L.In 83 normal control subject,they were 16% and 45% and (286 7?79 6)su/L respectively.The freqencies of DD genotype and D allele and ACE average activity had significant difference.Conclusion The deletion polymorphism of ACE gene might be an latent risk factor.The higher ACE activity might play an important role in the development of CHD.
