【摘要】 目的 分析不同压缩狭窄程度症状性心肌桥病人临床基线资料差异及对定量血流分数的影响。方法 选取2021年1月至2023年12月我院经冠脉造影证实的200例左前降支心肌桥患者作为研究对象，按照不同狭窄程度划分为1级组（n=120）、2级组（n=28）、3级组（n=52），对比三组一般资料、定量血流分数。结果 三组年龄、性别、高血压患病率等指标对比，差异无统计学意义（P>0.05）；肌桥伴随病变指标对比，三组差异有统计学意义（P<0.05）；不同狭窄程度，定量血流分数指标对比，差异有统计学意义（P<0.05）。结论 基于冠状动脉造影的定量血流分数评价症状性心肌桥有一定临床意义，能够为临床诊断、治疗提供可靠参考意见。更多还原

【Abstract】 Objective To analyze the differences in clinical baseline data of symptomatic myocardial bridge patients with different degrees of compression stenosis and their impact on quantitative blood flow fraction. Methods 200 patients with left anterior descending myocardial bridge confirmed by coronary angiography in our hospital from January 2021 to December 2023 were selected as the study subjects. They were divided into grade 1 group(n=120), grade 2 group(n=28), and grade 3 group(n=52) according to different degrees of stenosis. General information and quantitative blood flow scores were compared among the three groups. Results There was no statistically significant difference in age, gender, and prevalence of hypertension among the three groups(P>0.05). there was a statistically significant difference in the indicators of muscle bridge associated lesions among the three groups(P<0.05). There was a statistically significant difference in quantitative blood flow fraction indicators for different degrees of stenosis(P<0.05). Conclusion Quantitative blood flow fraction evaluation based on coronary angiography has certain clinical significance for symptomatic myocardial bridging. It can provide reliable reference for clinical diagnosis and treatment.更多还原
