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

Despite variable clinical results, beta 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 beta-blocker therapy in patients with the Marfan syndrome and noted improved aortic distensibility (3.0 +/- 0.3 vs 1.9 +/- 0.4 cm2 dynes(-1); p <0.02) and a reduced aortic stiffness index (8.0 +/- 2.9 vs 18.4 +/- 3.8; p <0.05) in patients receiving enalapril compared with those receiving beta blockers. These favorable hemodynamic changes were associated with a smaller increase in aortic root diameter (0.1 +/- 1.0 vs 5.8 +/- 5.2 mm) and fewer clinical end points during follow-up.
