[Ageing: a matter of heart?].

Abstract

Ageing is considered as a major risk factor for the development of chronic diseases. Among these, heart failure seems to be particularly important for both triggering and accelerating pathological ageing. In the present review, we give a general overview of the most relevant results concerning the mechanism of normal and premature senescence of cardiomyocytes and cardiac stromal cells. In particular, we will address the role of telomere dysfunction, DNA damage response, impairment of mitochondrial function, miRNAs and secretome of senescent cells in cardiac ageing and failure.
