Is flow-mediated vasodilator response to tachycardia of epicardial coronary arteries preserved in heart transplant recipients?
The vasodilator response of epicardial coronary arteries to tachycardia is preserved in heart transplant recipients. This suggests that the functional response of the endothelium to an increase in coronary blood flow remains normal in these patients.
Remifentanil and fentanyl have similar effects on absolute CBF, and cerebrovascular carbon dioxide reactivity is maintained.
