Abstract:
Blood pressure remains the single most important modifiable risk factor for the primary and secondary prevention of stroke. The landmark trial of the Perindoprii Protection Against Recurrent Stroke Study (PROGRESS) has suggested that the antihypertensive treatment with angiotensin-converting enzyme inhibitor (ACEI) perindopril at least 2 weeks after stroke may reduce the risks of recurrent stroke and other cardiovascular events. Although most systematic reviews have suggested that the efficacy of almost all types of antihypertensive drugs is similar in the prevention of stroke,there are also some important exceptions. The Ongoing Telmisartan Alone and in Combination with Ramipril Global End point Trial (ONTARGET) has demonstrated that the angiotensin receptor blockers (ARB) telmisartan was equivalent to ramipril for preventing cardiovascular events in patients with vascular disease or diabetes; while in a similar population,ramipril was quite effective for preventing stroke. It is speculated according to the moderating effects of ARB on the renin-angiotensin-aldosterone system that its protective effects against stroke is superior to other antihypertensives. However,many clinical trials have suggested that ARB does not have unique role in stroke prevention. Therefore,whether ARB should be regarded as the first-line drags for stroke prevention in both primary and secondary prevention settings has been controversial.
