ACCESSAcute Candesartan Cilexetil Evaluation in Stroke Survivors Early vs. delayed antihypertensive treatment with candesartan cilexetil in acute stroke patients with elevated BP A double blind, randomized, placebo controlled multicenter study Investigators: J. Schrader/Cloppenburg P. Dominiak/Lbeck
ACCESSAcute Candesartan Cilexetil Evaluation in Stroke Survivors Objective To compare the effect of an early (36-72 hrs post event) vs.a delayed (> 7 days post event) antihypertensive treatment with candesartan cilexetil in acute stroke with elevated BP. Hypothesis An early treatment with candesartan cilexetil improves the prognosis (mortality plus disability) of acute stroke patients with hypertension.
ACCESSAcute Candesartan Cilexetil Evaluation in Stroke Survivors Primary endpoint Total mortality and disability (functional status defined asBarthel Index £ 45) after 3 months. Secondary endpoint Combined criterion of - total mortality - cerebral complications - cardiovascular complications assessed 3 and 12 months after randomization

ACCESSAcute Candesartan Cilexetil Evaluation in Stroke Survivors Preliminary results: In March 2001, the study has prematurely been stopped witha total of 339 patients due to a significant difference infrequency of secondary endpoints between the two treatmentgroups.
ACCESSAcute Candesartan Cilexetil Evaluation in Stroke Survivors Results: • > 90 % treated with Atacand after double-blind period • Disability at 3 months not affected (primary endpoint). • Total mortality + vascular events at 12 months reduced by 48 %, from 18,7 % to 9,8 %, p < 0,02, in the early treatment group (reason for early stop, secondary endpoint).
