冠状动脉闭塞性血栓与该动脉支配区心肌梗塞之间的因果关系迄今仍有争论。作者对100例心肌梗塞心脏进行研究,结果提示冠状动脉急性闭塞性血栓在心肌梗塞的发病机理中不是原发因素。方法:100例临床及组织学确诊的急性心肌梗塞尸检心脏,每个心脏在未固定前,先摄X线片(后前位),然后经冠状动脉开口注入硫酸钡明胶剂,冷却后进行后前位,左、右前斜位X线摄影。此后,用10％福尔马林缓冲液固定心脏,对每一主要冠状动脉及其分支每间隔3毫米作切片检查。梗塞及纤维化的范围以求积仪测量,梗塞或瘢痕的体积大小以
The causal relationship between coronary occlusive thrombus and myocardial infarction in this arterial dominating area is still debated. The author of 100 cases of myocardial infarction heart study, the results suggest that acute coronary occlusive thrombosis in the pathogenesis of myocardial infarction is not a primary factor. Methods: 100 cases of clinically and histologically confirmed acute myocardial infarction autopsy heart, each heart before fixation, the first radiography (posterior), and then injected through the coronary artery opening barium sulfate gelatin, after cooling down Front, left and right anterior oblique X-ray photography. Thereafter, the heart was fixed with 10% formalin buffer and biopsied every 3 mm intervals for each major coronary artery and its branches. The extent of infarction and fibrosis is plotted as a plot, infarct or scar size
