The role of β‐adrenergic receptors in the regulation of cardiac tolerance to ischemia/reperfusion. Why do β‐adrenergic receptor agonists and antagonists protect the heart?

Catecholamines and β-adrenergic receptors (β-ARs) play an important role in the regulation of cardiac tolerance to the impact of ischemia and reperfusion. This systematic review analyzed the molecular mechanisms of the cardioprotective activity of β-AR ligands.
