Usefulness of enalapril versus propranolol or atenolol for prevention of aortic dilation in patients with the Marfan syndrome

Despite variable clinical results, β blockers have become the primary therapy for prevention of aortic dilation in patients with the Marfan syndrome. This study examines the use of the angiotensin-converting enzyme inhibitor enalapril for treatment of these patients. We sought to examine the effects of enalapril versus β-blocker therapy in patients with the Marfan syndrome and noted improved aortic distensibility (3.0 ± 0.3 vs 1.9 ± 0.4 cm 2...
