title: Coronary disease prediction using a new atherogenic index.
abstract: This report demonstrates the utilization of a new serum factor, Toxicity Preventing Activity (TxPA) in the diagnosis of coronary disease prone individuals. Our laboratory has recently identified TxPA, which offsets the toxicity of very low density lipoproteins (VLDL) upon arterial cells in vitro. In the present study, we measured TxPA activity and serum lipoprotein levels in 73 individuals undergoing coronary angiography. Serum from control subjects demonstrated 270% more TxPA than aged matched individuals with angiographically demonstrable coronary disease (CHD). When TxPA was combined with serum lipoprotein values, a new atherogenic index was generated which further distinguished these individuals with CHD from non-angiographed controls. These results demonstrate that TxPA is a new protective factor in coronary artery disease, and that the new atherogenic index provides for the first time an accurate classification of individuals with coronary artery disease.
