The incidence and prevalence of coronary disease, hypertension, heart failure and stroke increase exponentially with advancing age. While epidemiologic studies have discovered that aspects of lifestyle and genetics are risk factors for these diseases, age, per se, confers the major risk. Thus, it is reasonable to hypothesise that specific pathophysiological mechanisms that underlie these diseases become superimposed on cardiac and vascular substrates that have been modified by an 'ageing process', and that the latter modulates disease occurrence and severity. In order to unravel this age-disease interaction, the nature of the ageing process in the heart and vasculature requires elucidation. Some aspects of the current understanding of ageing of the heart and blood vessels in the absence of apparent disease are the focus of this review.
冠心病、高血压、心力衰竭和中风的发病率及患病率会随着年龄的增长呈指数级上升。虽然流行病学研究发现生活方式和基因方面是这些疾病的风险因素,但年龄本身才是主要风险因素。因此,有理由推测,这些疾病背后的特定病理生理机制叠加在了因“衰老过程”而发生改变的心脏和血管基质上,并且后者会调节疾病的发生和严重程度。为了阐明这种年龄与疾病的相互作用,需要对心脏和血管的衰老过程本质进行阐释。本文综述聚焦于目前对无明显疾病情况下心脏和血管衰老的一些认识。
