Homocysteine in relation to C-reactive protein and low-density lipoprotein cholesterol in assessment of cardiovascular risk.
Coronary vascular disease (CVD) is a chronic, multifactorial disease that occurs often in individuals without known risk factors. We investigated the predictive value of homocysteine (Hcy) in relation to C-reactive protein (CRP) and low-density lipoprotein (LDL)-cholesterol in patients with confirmed coronary disease. The study included 87 German and 92 Syrian patients in addition to 87 German and 64 Syrian control individuals. Patients and controls were of comparable age, lifestyles and cultural background. Patients of both ethnic groups had significantly higher concentrations of Hcy and C-reactive protein compared to the controls. The lipids were higher only in Syrian patients compared to the controls. Elevated concentrations of Hcy or that of CRP (>75th percentiles) were associated with increased probability for CVD. In both population groups, the risk increased markedly in subjects who had elevated concentrations of Hcy and CRP or those who had elevated concentrations of Hcy and LDL-cholesterol. The results emphasize that detemination of Hcy may improve the predictive value of C-reactive protein and the LDL-cholesterol. Measurements of these markers are especially important for identification of patients at high risk for CVD.
