Coronary artery disease has still a grave prognosis. More than half of
the patients die within 24 hours, mostly before reaching a hospital.
A minority survives the first year. Only more intense prevention will
change this. Primary prevention in a narrow sense refers to the preven
tion of the development of early lesions in the youth and as such is a
responsibility of the education towards a healthy lifestyle. In our p
opulation a majority of middle-aged is likely to have developed arteri
osclerosis, so that we deal only with clinically defined primary preve
ntion even though they are asymptomatic. The outstanding effects of li
pid therapy in patients at risk for coronary heart disease will primar
ily result from evoiding the development of instable plaques. Reductio
n of LDL-cholesterol and increase of HDL-cholesterol is most effective
in patients with proven coronary artery disease. Evidently the majori
ty of coronary events can be prevented by idealizing the lipid paramet
ers. In contrast, the chronic coronary syndrome is the domain of the i
nterventional cardiology. Lipid therapy will lead only gradually to a
reduction of significant coronary stenoses. However, there is the stil
l insufficiently investigated potential of improving the endothelial d
ysfunction by correcting the lipid metabolism to reduce angina.
