Background: With increasing age, human ventricular myocardium exhibits selective downregulation of β1-adrenergic receptors (β1-ARs). We tested the hypothesis that sex differences exist in age-related changes in β1-ARs.
Methods: Left (LV) and right (RV) ventricular tissue was obtained from 61 unplaceable potential organ donor hearts ages 1 to 71 years with no known cardiac history and from LVs removed from 56 transplant recipients with idiopathic dilated cardiomyopathy.
