E N D
Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT) Design • Multicenter trial with 2 treatment comparisons • A prospective, randomized, open, blinded endpoint (PROBE) design comparing 2 antihypertensive regimens in hypertensive men and women without known CHD who had 3 other CV risk factors (n=19,342) • A double-blind, placebo-controlled trial of atorvastatin 10 mg/d in the subsample of patients with total cholesterol 250 mg/dL (n=10,305) • Primary endpoint: nonfatal MI (including silent MI) or CHD death • Planned follow-up average of 5 yr; lipid-lowering arm stopped early at median follow-up of 3.3 yr Sever PS et al.
