[Secondary prevention of stroke].

Because of its frequency and its impact in terms of human, social, and economic consequences, stroke represents a major public health issue whose burden is dramatically increasing due to the ageing population. Secondary prevention after ischemic stroke and transient ischemic attack concerns both the risk of cerebrovascular recurrences, and that of non-neurological ischemic events including myocardial infarction. Hence, this prevention relies on three keypoints: antithrombotic therapy, correction of vascular risk factors, and revascularization in case of carotid stenosis according to well-de- fined criteria. Less data about secondary prevention after intracerebral hemorrhage are available, and treatment of hypertension is the main target.
