摘要
The present invention describes methods for treating heart diseases by pharmacological manipulation of intrinsic cardiac adrenergic cells. The activation or inhibition of δ-opioid receptors or selective β2-adrenergic receptor agonist in these cells can help regulate catecholamine synthesis and release in these cells. Thus drugs directed towards these receptors can be used in the treatment of heart diseases including acute and chronic congestive heart failure, as well as acute and chronic coronary artery disease. The present invention also describes a method of treating acute decompensated congestive heart failure using δ-opioid receptor agonists or selective β2-adrenergic receptor agonists to stimulate endogenous production of brain natriuretic peptide. This invention also provides a novel strategy for protection against myocardial ischemia through the specific activation of δ-opioid receptors or selective β2-adrenergic receptor agonists exclusively expressed by intrinsic cardiac adrenergic cells in human heart. The activation of intrinsic cardiac adrenergic cells by δ-opioid receptor stimulation enhances endogenous catecholamine release, which subsequently stimulates myocardial alpha 1-adrenoreceptors achieving myocardial protection in patients suffering from myocardial ischemia due to coronary artery disease.
