Summary

To study the variation and significance of plasma coagulation factor VII (FVII) in different kinds of ischemia heart disease (IHD) and examine its relation with plasma lipid and gene polymorphism. FVIIa was determined with one stage clotting assay by using a recombinant soluble tissue factor (rsTF). FVIIc was measured with one stage clotting assay. FVIIag was quantified with an enzyme-linked immunosorbent assay (ELISA). Polymorphism was analyzed with PCR-urea-polyacrylamide gel electrophoresis. Our results showed that FVIIa in stable angina (SA), unstable angina (UA), obsolete and acute myocardial infraction (OMI, AMI) patients was higher than those of normal group with the differences being significant within any two groups. FVIIag in UA, OMI and AMI was higher than those in SA and normal groups. There were positive correlations between FVIIa and serum triglycerides, FVIIa and FVIIc, FVIIc and FVIIag. FVII-323 0/10 bp polymorphism analysis was performed in 60 patients and 0/10 bp polymorphism was found in 5 cases. FVIIc and FVIIag were much lower in cases of 0/10 bp groups than those in cases of 0/0 bp groups. It is concluded that there was activation of extrinsic coagulation pathway in every kind of IHD to different extent. FVIIa was the risk factor in the development of IHD, and more sensitive in reflecting the severity of cardiovacutar disease than FVIIc or FVIIag. FVIIa was higher in OMI, which may be one of the risk factors of re-infraction. Serum triglyceride may indirectly lead to the development of IHD by increasing the level of FVIIa. FVII-323 0/10 by polymorphism was present in Chinese patients with IHD and it was correlated with the level of FVIIc, FVIIag in plasma. 10 bp allelomorphic gene was a protective factor against thrombogenesis.
