Acute stimulation of β-adrenergic receptors (β-ARs), for example during physical activity, leads to the synthesis of the second messenger cAMP in cardiomyocytes, which triggers a cascade of events leading to the increase of cardiac function. While acute β-AR stimulation is beneficial to the heart, chronic β-AR activation is detrimental because it promotes cardiac remodeling and ultimately leads to heart failure (HF). HF is defined by the heart's inability to overcome hemodynamic needs of the body. While the majority of patients die of worsening heart function, a significant proportion dies suddenly of cardiac arrhythmias.Phosphodiesterases (PDEs) are crucial enzymes since they allow not only to terminate cAMP signals by degrading this secon...
