Abnormal Vascular Responses to Exercise in Patients with Aortic Stenosis

RESUMO
We tested the hypothesis that the normal forearm vasoconstrictor response to leg exercise is inhibited or reversed in patients with aortic stenosis, possibly because of activation of left ventricular baroreceptors. Forearm vascular responses to supine leg exercise were measured in 10 patients with aortic stenosis and in 2 control groups of 6 patients with mitral stenosis and 5 patients without valvular heart disease.
