Stroke management.

BACKGROUND

Stroke is the third most common cause of death in most resource-rich countries. It is a worldwide problem; about 4.5 million people die from stroke each year. Stroke can occur at any age, but half of all strokes occur in people aged over 70 years. About 80% of all acute strokes are ischaemic, usually resulting from thrombotic or embolic occlusion of a cerebral artery. The remainder are caused either by intracerebral or subarachnoid haemorrhage.

METHODS

We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of specialised care in people with acute stroke? What are the effects of medical treatment in people with acute ischaemic stroke? What are the effects of surgical treatment for intracerebral haematomas? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2007 (BMJ Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

RESULTS

We found 42 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

CONCLUSIONS

In this systematic review we present information relating to the effectiveness and safety of the following interventions: acute reduction in blood pressure, aspirin, evacuation (early surgical evacuation, or conservative treatment), neuroprotective agents (calcium channel antagonists, citicoline, gamma-aminobutyric acid agonists, glycine antagonists, lubeluzole, magnesium, N-methyl-D-aspartate antagonists, tirilazad), specialised stroke care, systemic anticoagulation (heparinoids, low or specific thrombin inhibitors, molecular weight heparin, oral anticoagulants, unfractionated heparin), and thrombolysis.
