The study on COgnition and Prognosis in the Elderly (SCOPE) - Major CV events and stroke in subgroups of patients

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 indicates 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.
