Vascular Sensitivity to Adrenergic Agonists in Patients With CHF and in Healthy Subjects
Vascular Sensitivity to Adrenergic Agonists in Patients With CHF and in Healthy Subjects
Congestive Heart failure (CHF) is asociated with changes in cardiac function and vascular
 responses. The aim of this study is to characterize these differences. Our hypothesis is,
 that there are differences in vascular responses between healthy subjects and patients with
 CHF.
