Study design

The Insulin Carotids US Scandinavia Study (ICARUS) is a two-arm clinical trial and a substudy of the Losartan Intervention For Endpoint Reduction in Hypertension Study (LIFE) based in the centres at Glostrup, Copenhagen, and Ullevaal, Oslo. The principal aim of the trial was to investigate the effect of Atenolol (50-100mg/day) versus Losartan (50-100mg/day) on carotid artery plaque development in hypertensive patients with left ventricular hypertrophy. Individuals were eligible for inclusion if they were aged between 55 and 80 years with previously treated or untreated hypertension and electrocardiography signs of left ventricular hypertrophy. All patients provided written informed consent, and the substudy protocol was approved by all relevant ethics committees.
