Intraoperative myocardial biopsy specimens taken from 50 patients with coronary heart disease were studied to examine ultrastructure of myocardial capillaries. It was found that this disease was characterized by abundant myocardial capillaries with a narrowed lumen. Quantitative stereological analysis indicated that the ultrastructure of the capillaries with narrowed lumen was not substantially different from that of open capillaries. The findings showed that the narrowed capillaries to be reserve and capable of providing an adequate blood supply of cardiomyocytes after aortocoronary bypass surgery.
对50例冠心病患者术中获取的心肌活检标本进行研究，以检查心肌毛细血管的超微结构。发现该疾病的特征是心肌毛细血管丰富但管腔狭窄。定量体视学分析表明，管腔狭窄的毛细血管的超微结构与开放毛细血管的超微结构没有实质性差异。研究结果表明，狭窄的毛细血管具有储备功能，在主动脉冠状动脉搭桥手术后能够为心肌细胞提供充足的血液供应。
