本文在 50例心脏上测量了心肌桥位置的长、宽、厚度 ;并在光镜下观察了壁冠状动脉的结构。发现桥前段血管内膜较桥下、后段的内膜显著增厚 (P<0 .0 1) ,讨论了它与冠状动脉粥样硬化间的关系。
The length, width and thickness of the myocardial bridge were measured in 50 cases of heart. The structure of the wall coronary artery was observed under light microscope. It was found that the intima of the anterior segment of the bridge was significantly thicker than the posterior segment of the bridge and posterior segment of the intima (P <0.01), and its relationship with coronary atherosclerosis was also discussed.
