Emerging antithrombotic treatments for acute coronary syndromes.
In the last few years the hypothesis of coronary thrombosis, frequently triggered by plaque ulceration or fissuration, has gained wide acceptance as one of the key events in the pathophysiology of acute coronary syndromes. Plaque ulceration may activate both platelets and the coagulation cascade via exposure of a variety of substances, such as von Willebrand factor and tissue factor. It has been demonstrated that aspirin reduces mortality and improves the prognosis of patients with such syndromes. More recently, newer drugs have been identified for the treatment of acute coronary syndromes; in particular, platelet glycoprotein IIb/IIIa inhibitors have been found to be more effective than aspirin in a variety of clinical conditions, such as unstable angina, acute myocardial infarction, and coronary angioplasty. Other drugs with different mechanisms of action will be soon available for large scale clinical trials.
