| 中文摘要: |
| 冠状动脉血流储备是临床评价冠脉循环能力的重要指标之一, 既往多采用介入性方法进行测定。本研究应用经胸超声心动图冠脉血流显像新技术观察17例正常成人静脉内注射潘生丁结合等长握力应激状态下心外膜冠脉血流的变化, 结果显示最大血流变化出现在实验开始后第4～5分钟, 峰值血流速度比3.771±0.812, 舒张期峰速积分比为3.529±0.041.全部受试者无明显不良反应。表明冠状动脉血流显像新技术结合潘生丁握力实验是一可行的无创性评价正常冠脉血流储备的新方法。 |

| This study observed the change of epicardial coronary flow during intravenous dipyridamole combined with sustained isometric handgrip exercise in 17 normal volunteers to estimate coronary flow reserve using coronary flow imaging.The maximal responses of coronary flow occurred at 4-5 minutes after stress giving.The peak velocity of coronary flow increased to 3.771×baseline value and the velocity time integral to 3.529×baseline value,respectively.The results demonstrated that the coronary flow imaging combined with intravenous dipyridamole and isometric handgrip may be useful to estimated the coronary flow reserve noninvasively. |
