Analysis of post coronary bypass surgery risk factors and scoring system with study of immunogenetic epidemiology

Coronary heart disease patients with 308 polymorphism (particularly heterozygote G-A polymorphism) have a higher circulating TNF a concentration compared to CHD patients without polymorphism. The post surgical clinical manifestations were not proven to be influenced by circulating TNF á concentrations. It is thought that the increase was not enough to yield clinically manifestation.
