Unstable angina and non-Q-wave myocardial infarction still represent an uns
olved problem for clinicians, owing to their unpredictable evolution and hi
gh incidence of coronary events in the follow-up.
Traditional antithrombotic agents, unfractionated heparin and aspirin, have
been proved to be highly effective, but show some important limitations. N
ew potent antithrombotic therapy have been studied to improve their efficac
y, with encouraging results. Among these drugs, low molecular weight hepari
ns (for subcutaneous administration) and inhibitors of platelet glycoprotei
n receptor IIb/IIIa (for intravenous, and possibly oral, administration) ar
e the most promising and are now under extensive investigation. (C) 1999 El
