[Anticoagulation in cardiology].

The various applications of anticoagulation in cardiology concern primary prevention, treatment of angina and infarction, revascularization either by angioplasty or by bypass grafts, treatment after artificial valve replacement, treatment of atrial fibrillation and, finally, as a precaution in the case of impaired ventricular function. Several methods of anticoagulation can be used in each of these indications: thrombin antagonists, vitamin K antagonists, antiaggregants and thrombolytics, although this last group is not discussed in this article.
