Transgenic mice with intense cardiac expression of human β-adrenergic receptor gene were engineered and shown to display market improvements in baseline myocardial and left ventricular function. Heart/body weight ratios and histologic appearance were not found to be significantly altered, suggesting that receptor gene expression did not induce pathologic changes. Given the substantial reduction in β-adrenergic receptor density and result reduction in inotropic responsiveness observed in chronic heart failure, these finding represent a novel approach for increasing myocardial function with important clinical implications.
