Abstract
On the basis of a two-year follow-up, Thompson et al. (March 9 issue)1 conducted a prospective study to evaluate the influence of hemostatic factors on cardiovascular risk. The authors report that patients with high cholesterol levels but low fibrinogen levels had a low risk of coronary events. They conclude that the fibrinogen level can be used to identify patients with hypercholesterolemia who are at particularly high risk for coronary events.
