Cerebral oxygenation during exercise and exercise recovery in patients with idiopathic dilated cardiomyopathy.
We compared cerebral oxygenation during exercise and during exercise recovery between 22 healthy subjects and 35 patients with idiopathic dilated cardiomyopathy (IDC). Although cerebral oxyhemoglobin increased during exercise in most of the healthy subjects, oxyhemoglobin decreased during exercise in 15 of 35 patients with IDC. Cerebral oxygenation during exercise and exercise recovery was related to left ventricular function in the patients with IDC.
