Comparative Study
Retrospective analysis of the effect of angiotensin II receptor blocker versus β-blocker on aortic root growth in paediatric patients with Marfan syndrome.
Cardiovascular pathology, including aortic root dilation at the level of sinus of Valsalva (SV), is one of the major causes of morbidity in paediatric patients with Marfan syndrome (MFS). β-Blocker (BB) is well established to slow aortic dilation in MFS. Less is known about the effectiveness of angiotensin II receptor blocker (ARB) on aortic dilation in paediatric patients with MFS. ⋯ Both concepts lead to a significant reduction of SV dilation. The effect of ARB and BB is similar. This is the first study concerning the comparison of ARB and BB in previously untreated paediatric patients with MFS. The results of the study show that both treatment strategies are beneficial in paediatric and adolescent patients.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of contemporary troponin assays with the novel biomarkers, heart fatty acid binding protein and copeptin, for the early confirmation or exclusion of myocardial infarction in patients presenting to the emergency department with chest pain.
To examine the diagnostic accuracy of novel biomarkers of myocardial injury and troponin assays for diagnosis of myocardial infarction. ⋯ High-sensitivity cardiac troponin is the best single marker. Addition of HFABP to high-sensitivity troponin increased diagnostic sensitivity. Additional measurement of copeptin is not useful in the chest pain population.
