Abstract

Stroke is a highly prevalent disorder worldwide; it is the third main cause of death and the leading cause of severe disability. Recent data showed that 72-86% of cerebrovascular disorders are of ischaemic type. Arterial hypertension is the most prevalent risk factor for both haemorrhagic and ischaemic stroke, it is present in approximately 70% of cases. All forms of hypertension, isolated systolic or diastolic and combined hypertension increase stroke risk about 3-4 times and the relationship with systolic blood pressure may even be stronger than with diastolic blood pressure. Hypertension is very common after acute stroke. In this phase the cerebral autoregulation is disturbed in the region of focal brain ischaemia or haemorrhage such that cerebral blood flow is directly dependent on systemic blood pressure. It is therefore essential to avoid systemic hypotension in acute stroke patients and the reduction of high blood pressure may lower cerebral blood flow in the ischemic penumbra. Evidence from clinical data shows that control of blood pressure leads to lower risk of first or reccurent stroke and patients have shown beneficial effects especially of ACE inhibitors and diuretics. In the PROGRESS study both hypertensive and non-hypertensive cerebrovascular patients benefited from antihypertensive therapy. Previous results suggests that there may be additional beneficial effects of the ACE-inhibitor therapy not related to blood pressure lowering in the prevention of stroke.
