Outcome Measures Primary - Rate of change in total coronary calcium scores by CT

Secondary Change in blood values and endothelial function over 6 and 12 months:

1. Plasma lipids: total plasma cholesterol and triglycerides, LDL-Cholesterol, HDL-Cholesterol, and VLDL-Cholesterol determined by the precipitation method;
2. Endothelial markers and inflammation: C-reactive protein and Homocysteine, as well as GSH
