Marfan's syndrome is a genetic disorder affecting connective tissues, and it can lead to death due to aortic defects if left untreated. beta-blocker therapy has been used to slow the progression of this disease. Brooke et al. (2008) now report that combining angiotensin II receptor blockade by losartan with beta-blocker treatment is an effective treatment combination therapy for this disorder.
