Randomized Controlled Trial Comparative Study
[Study of the efficacy and safety of losartan versus atenolol for aortic dilation in patients with Marfan syndrome].
Marfan syndrome is an inherited disease of the connective tissue. Recent trials have indicated the use of losartan (a transforming growth factor beta inhibitor) in these patients prevents aortic root enlargement. The aim of our clinical trial is to assess the efficacy and safety of losartan versus atenolol in the prevention of progressive dilation of the aorta in patients with Marfan syndrome. ⋯ Efficacy of losartan versus atenolol in the prevention of progressive dilation of the aorta, improved aortic distensibility, and prevention of adverse events (aortic dissection or rupture, cardiovascular surgery, or death) will be assessed in this study. It will also show the possible treatment benefits at different age ranges and with relation to the initial level of aortic root dilation.
