High plasma immunoreactive endothelin levels in patients with Chagas’ cardiomyopathy

2001 
Based on these data, it is impossible to predict the presence or absence of coronary artery disease in patients with aortic stenosis based on symptoms. As a result, we recommend that all patients with aortic stenosis undergo coronary angiography in preparation for valve replacement. 1. Vandeplas A, Willems JL, Piessens J, DeGeest H.
