概念:心源性休克是一个综合征。由于心肌严重损伤引起心输出量急剧下降,继而周围循环机能障碍、衰竭,组织血液灌注量降低,产生代谢性酸中毒。特点是既有周围循环衰竭,又有心排血功能障碍,故在发病机理、临床表现和抢救方面更为复杂。病因 1.心肌功能不全型:(1)急性病:如心肌梗死有15%合并休克,为常见原因;其他如克山病、心肌炎、严重心律失常等。(2)慢性病:各种严重心脏病,晚期心力衰竭。
Concept: Cardiogenic shock is a syndrome. Due to severe myocardial injury caused by a sharp decline in cardiac output, followed by circulatory dysfunction, failure, tissue blood perfusion decreased, resulting in metabolic acidosis. Is characterized by both the surrounding circulatory failure, there are cardiac dysfunction, so the pathogenesis, clinical manifestations and rescue more complex. Etiology 1. Myocardial dysfunction type: (1) Acute diseases: such as myocardial infarction with 15% of shock, a common cause; others such as Keshan disease, myocarditis, severe arrhythmia. (2) chronic diseases: a variety of serious heart disease, advanced heart failure.
