Primary And Secondary Prevention Of Stroke

Despite considerable advances in acute stroke therapy, stroke prevention remains the most promising approach for reducing the burden of stroke. A healthy lifestyle and the treatment of cardiometabolic risk factors are the cornerstones of both primary and secondary stroke prevention. Due to a proportionately higher risk of bleeding complications, platelet inhibitors are not recommended for primary stroke prevention. Platelet inhibitors are effective in the secondary prevention of stroke with acetyl salicylic acid (ASS) and clopidogrel showing the most consistent data. New oral anticoagulants are slightly more effective than coumarin and significantly reduce the risk of intracranial hemorrhage. They offer the opportunity to bring more patients with atrial fibrillation at risk for stroke into anticoagulation particularly those on ASS therapy. Surgery for patients with asymptomatic carotid artery stenosis should be viewed critically with respect to an only marginal benefit and improvement in medical therapies. Carotid endarterectomy remains the gold standard for patients with symptomatic carotid stenosis because of an increased procedural stroke risk with carotid stenting. Patients with symptomatic intracranial stenosis or cryptogenic stroke and a patent foramen ovale should receive only medical treatment.
