Marfan Syndrome Clinical Trial
Official title:
A Clinical Trial to Assess the Efficacy and Safety of Losartan Versus Atenolol in the Prevention of Progressive Dilation of the Aorta in Patients With Marfan Syndrome.
The purpose of this study is to evaluate the efficacy of Losartan versus Atenolol in the progression of aortic dilatation in patients with Marfan syndrome.
Marfan syndrome is a genetic disease of the connective tissue. Patients with Marfan syndrome
experience an expansion of the aorta that can lead to dissection or rupture of it. This is
the main cause of mortality in these patients.
The main objective of this study is to evaluate the efficacy of Losartan versus Atenolol in
the progression of aortic dilation in patients with Marfan syndrome.
The measurement is made by echocardiography, assessing the diameter of the aorta in
different zones: valve annulus, sinuses of Valsalva, sinotubular junction, ascending aorta,
aortic arch, thoracic and abdominal aorta.
A total number of 150 subjects diagnosed with Marfan syndrome and who meet the diagnostic
criteria of Ghent, of both sexes, 75 per treatment group, aged between 5 and 60, will be
included in the study. The study is being conducted in two Spanish hospitals.
The treatment is maintained throughout the study period.
