STROKE (cerebrovascular accident)
Occurs when part of the brain is deprived of its blood supply. It is the third biggest cause of death in the UK and the largest single cause of severe disability. The two main types of stroke are:
Atrial fibrillation (AF) is a major cause of stroke. Approximately 10% of ischaemic strokes occur in people with undiagnosed AF. A state of hypercoagulation develops during AF, due to stasis and turbulence in the atria. This can lead to the development of clots which go on to cause thromoembolic events. The risk of stroke can be significantly reduced with anticoagulant treament. Calculate risk using CHA2DS2VASc

Arm weakness – can the patient raise both arms?
Speech problems – can patient speak clearly and understand what you say?
