Syst-Eur Trial The Systolic Hypertension in Europe (Syst-Eur) Trial enrolled 4,695 patients 60 years old, with hypertension, for a median follow-up of 24 months (range 1-97 months) Participants were randomly assigned to nitrendipine, plus enalapril and hydrochlorothiazide if needed, or to placebo The primary endpoint was a composite of fatal and non-fatal stroke Other endpoints included congestive heart failure, myocardial infarction, sudden death, and all cardiac endpoints (a composite of congestive heart failure, myocardial infarction and sudden death) 492 patients had diabetes at baseline Staessen JA, et al. Lancet. 1997;350:757-764.

Syst-Eur Conclusions • Older men and women with isolated systolic hypertension who received active treatment with a dihydropyridine calcium channel blocker experienced fewer strokes and cardiovascular disease (CVD) events than those receiving placebo. • Treatment of 1,000 patients for 5 years with this type of regimen could prevent 29 strokes or 53 major CVD endpoints.
