摘 要:目的分析冠状动脉慢血流现象与左心功能和冠状动脉直径的相关性。方法将2017年3月—2019年9月收治的行冠状动脉造影检查为冠状动脉慢血流的80例作为研究组,选取同时间行冠状动脉造影正常疑似冠心病80例作为对照组。观察2组左心功能和冠状动脉直径,分析冠状动脉慢血流现象与左心功能及冠状动脉直径的相关性。结果研究组前降支、回旋支、右冠状动脉的血流帧数和直径均大于对照组(P<0.01)。研究组二尖瓣舒张晚期血流峰速度及左心室舒张功能低于对照组,等容舒张期时间长于对照组(P<0.05,P<0.01)。冠状动脉慢血流与TIMI血流计数、冠状动脉直径和等容舒张期时间呈负相关,与左心室舒张功能呈正相关(P<0.05,P<0.01)。结论冠状动脉慢血流现象与患者左心功能和冠状动脉直径息息相关。冠状动脉血流越慢,直径越大,左心室舒张功能越差。Objective To analyze the correlation between slow coronary flow(SCF)and left ventricular function and coronary artery diameter.Methods Eighty patients diagnosed with SCF by coronary angiography and treated in our hospital from March 2017 to September 2019 were selected as the research group,and 80 cases with suspected coronary heart disease and normal coronary artery by angiography in our hospital during the same period were selected as the control group.Left heart function and coronary artery diameter were observed in the two groups,and the correlation between SCF and left ventricular function and coronary artery diameter was analyzed.Results The frame number of blood flow and diameters in the anterior descending,circumflex,and right coronary artery of the research group was significantly larger than those of the control group(P<0.01).The peak velocity of mitral valve during late diastole and diastolic function of the left ventricle in the research group were significantly lower than that in the control group,and the isovolumetric relaxation phase was longer than that in the control group(P<0.05,P<0.01).SCF was negatively correlated with TIMI flow count,coronary artery diameter and isovolumetric relaxation phase,and positively correlated with E/A(P<0.05,P<0.01).Conclusion SCF is closely related to left heart function and coronary artery diameter.The slower the coronary blood flow,the larger the coronary artery diameter,and the worse the left ventricular diastolic function.
