将三组尸检患者的心脏相比较,作者对急性心肌梗塞休克的发生,有如下观点:一、心源性休克,多发生于左室心肌大面积坏死(近40％或更多)的患者,源于心收缩力衰竭;二、冠状动脉血流压力降低,使梗塞面积扩大,加重心肌损伤;三、冠状动脉供血不足,双侧心室缺血,出现散在灶性坏死。大面积心肌梗塞后出现恶性循环,心肌功能损伤加重,进一步扩大梗塞范围,使心肌功能更低下。致使病情不易逆转。故应于心肌梗塞早期估计其预后,发病数小时,休克仍不见恢复时,即应考虑用体外循环改善心脏循环,或用冠状静脉移植建
The three groups of autopsy patients compared to the heart, the author of the occurrence of acute myocardial infarction, the following points: First, cardiogenic shock, mostly in large areas of left ventricular myocardial necrosis (nearly 40% or more) of patients, Third, coronary insufficiency, bilateral ventricular ischemia, scattered focal necrosis appeared. A large area of myocardial infarction after a vicious cycle, increased myocardial injury, to further expand the infarct range, so that lower myocardial function. Cause the disease is not easy to reverse. It should be estimated early in the prognosis of myocardial infarction, the number of hours of onset, shock is still not seen, that should be considered with cardiopulmonary bypass to improve cardiac circulation, or coronary vein graft
