The Study on COgnition and Prognosis in the Elderly (SCOPE) assessed the effect of candesartan on cardiovascular outcomes in elderly patients with mild to moderate hypertension. Patients were randomized to candesartan 8-16 mg daily (n = 2477) or placebo (n =2460). Due to extensive add-on therapy, blood pressure reduction was only about 3/2 mmHg greater in the candesartan group than in the control group. Nevertheless, non-fatal stroke was reduced by 28% (p = 0.04) in the candesartan group compared to the control group, and there was a non-significant 11% reduction in major cardiovascular events (p = 0.19). This report provides results in pre-specified subgroups of patients (age, gender, diabetes, history of stroke, smoking and cardiovascular risk at randomization). Reductions in major cardiovascular events and stroke with candesartan-based therapy were indicated in all subgroups. A significant interaction between treatment and subgroups was found for one pair of subgroups only; the reduction in major cardiovascular events with candesartan was greater in patients with a previous stroke (64% reduction, p = 0.004) than in those without (5% reduction, p > 0.20). In conclusion, this analysis indicated consistent favourable effects of candesartan-based therapy on major cardiovascular events and stroke across the different subgroups of patients. However, the benefit was particularly pronounced in patients who entered the study with a previous stroke.
老年人认知与预后研究(SCOPE)评估了坎地沙坦对轻至中度高血压老年患者心血管结局的影响。患者被随机分为每日服用8 - 16毫克坎地沙坦组(n = 2477)或安慰剂组(n = 2460)。由于广泛的附加治疗,坎地沙坦组的血压降低幅度仅比对照组大约高3/2毫米汞柱。尽管如此,与对照组相比,坎地沙坦组的非致命性卒中减少了28%(p = 0.04),主要心血管事件减少了11%,差异无统计学意义(p = 0.19)。本报告提供了预先指定的患者亚组(年龄、性别、糖尿病、卒中史、吸烟情况以及随机分组时的心血管风险)的结果。基于坎地沙坦的治疗在所有亚组中均显示出主要心血管事件和卒中的减少。仅在一对亚组中发现治疗与亚组之间存在显著交互作用;既往有卒中的患者使用坎地沙坦后主要心血管事件的减少幅度(降低64%,p = 0.004)大于无卒中患者(降低5%,p > 0.20)。总之,该分析表明基于坎地沙坦的治疗对不同患者亚组的主要心血管事件和卒中具有一致的有利影响。然而,这种益处在入组时已有卒中的患者中尤为明显。
