Blood pressure and lipid lowering in the prevention of stroke: A note to neurologists

Stroke is the leading cause of adult disability and dependency in western society. Despite the determined efforts of basic science and clinical investigators, neuroprotective therapies for acute stroke have yet to be realised. Stroke prevention, therefore, remains the key route for reducing morbidity and mortality. Hypertension and hypercholesterolaemia are the most important modifiable risk factors for stroke. Several recent landmark studies have shown that lipid lowering with statins can reduce the risk of ischaemic stroke, as well as coronary heart disease. In addition, clinical trials evaluating the effects of blood pressure lowering have shown that antihypertensive agents such as angiotensin-converting enzyme (ACE) inhibitors, calcium channel blockers (CCBs) and angiotensin 11 receptor antagonists can reduce stroke risk. Accumulating evidence suggests certain antihypertensive agents such as CCBs might also prevent the formation and progression of carotid atheroma, independently of their blood-pressure-lowering effects. It follows that rigorous identification and targeting of high-risk or stroke-prone individuals for blood pressure and lipid-lowering interventions should be of practical importance to all physicians involved in the management of stroke.
