Abstract:

Heart failure is the final stage of the development of various cardiovascular diseases. Because of its high mortality rate and poor prognosis, it has become a major disease that endangers human life and health. In heart failure, the sympathetic system is activated and the catecholamines stimulate β-adrenergic receptor (β-AR) to increase cardiac output via Gs-AC-cAMP-PKA signaling pathway, which is beneficial in the acute phase, but chronic β-ARs stimulation eventually leads to a diminished contractile performance of the heart. A-kinase anchoring protein (AKAP) plays an important role in this pathological process, which regulates signaling pathways by anchoring PKA in specific subcellular locations. β-blockers are widely used in the treatment of heart failure, but also have a range of side effects.Therefore, novel and more targeted therapeutic treatments are needed to improve treatment of HF in the future.

Key words: kinase anchoring protein, heart failure, protein kinase A, β-adrenergic receptor
