Abstract This study looks at the possible role of some non-traditional risk factors for premature coronary artery disease (CAD) and assesses the presence of relationship between these factors and the traditional cardiovascular risk factors. The study subjects (n=45) are divided into three groups comprising 15 premature CAD patients without traditional cardiovascular risk factors (group I); 15 premature CAD patients with one or more traditional cardiovascular risk factors (group II); and 15 healthy normal control subjects matched for age and sex (group III). Estimation of plasma homocysteine (Hcy) and plasminogen activator inhibitor-1 (PAI-1) is performed by enzyme-linked immunosorbent assay (ELISA); plasma folic acid by radioimmunoassay; plasma lipoprotein a (Lpa) by turbidimetry; and plasma lipids by colorimetry. Results showed a significant association between elevated Hcy and low folate levels and premature CAD in both patient groups. Also, a significant association was seen between elevated PAI-1 and CAD in the two patient groups, and between CAD and high levels of Hcy and triglycerides, as well as a low level of high-density lipoprotein cholesterol. Lpa showed significant association with premature CAD only in group II. Thus, Hcy, folic acid and PAI-1 might serve as independent risk factors for premature CAD in patients both with and without traditional coronary risk factors. However, Lpa might confer an additional coronary risk factor only in the presence of traditional risk factors.
