【摘要】:心力衰竭(簡稱心衰)是一種復(fù)雜的臨床綜合征,任何心室結(jié)構(gòu)或功能受損所導(dǎo)致的充盈障礙或射血障礙均可引起心力衰竭。發(fā)達國家成年人群心力衰竭患病率達到1%~2%,而70歲以上的老年人群患病率升高到≥10%。隨著人口的老齡化以及冠心病患病率的增加,心力衰竭患病率有上升趨勢,并且已經(jīng)成為人類致殘、致死的重要疾病。心衰受到體內(nèi)各種神經(jīng)體液因素的調(diào)節(jié),中樞神經(jīng)激素如:腎素-血管緊張素系統(tǒng)(renin-angiotensin system,RAS)、炎性細胞因子(proinflammatory cytokines,PIC)、活性氧簇(reactive oxygen species,ROS)等的改變可能與心衰中樞活動增強密切相關(guān),并可以明顯改變外周交感神經(jīng)的活動。持續(xù)的交感神經(jīng)活動增強是心衰發(fā)生發(fā)展的重要原因,因此降低交感神經(jīng)興奮性成為心衰治療研究的焦點之一。本文著重論述中樞神經(jīng)激素對心衰的影響和可能的中樞調(diào)控機制。
