Relation between depressed cardiac response to exercise and autonomic nervous activity in mildly symptomatic patients with idiopathic dilated cardiomyopathy.

We investigated whether the depressed cardiac response to adrenergic stimulation is accompanied with impaired autonomic function in mildly symptomatic patients with idiopathic dilated cardiomyopathy (DCM). Twenty-seven patients with DCM (New York Heart Association class I or II) and 7 normal control subjects underwent exercise radionuclide ventriculography… (More)
