An Alternative Method to Calculate Simplified Projected Aortic Valve Area at Normal Flow Rate

Arq. bras. cardiol; 110 (2), 2018
Abstract Background: Simplified projected aortic valve area (EOAproj) is a valuable echocardiographic parameter in the evaluation of low flow low gradient aortic stenosis (LFLG AS). Its widespread use in clinical practice is hampered by the laborious process of flow rate (Q) calculation. Objetive: This...

Role of adenylyl cyclase in reduced β-adrenoceptor-mediated vasorelaxation during maturation

Braz. j. med. biol. res; 49 (7), 2016
Beta-adrenergic receptor (βAR)-dependent blood vessel relaxation is impaired in older animals and G protein activation has been suggested as the causative mechanism. Here, we investigated the role of βAR subtypes (β1AR, β2AR, and β3AR) and cAMP in maturation-dependent vasorelaxat...
