摘　　要：目的探讨多模态心脏磁共振对肥厚型心肌病的诊断价值。方法选取2020年1月—2023年1月牡丹江医学院附属第二医院收治的肥厚型心肌病患者50例归入试验组,根据有无左心室流出道梗阻分为研究1组(有梗阻,n=21)与研究2组(无梗阻,n=29)。选取同一时段牡丹江医学院附属第二医院接收的健康体检者21例归入对比组。所有纳入者均接受多模式心脏磁共振检查。比较不同组别的左心室心肌过度小梁化的分形维数值、每次心动周期的左心室血流模式、左心室功能相关指标的差异性。结果经过扫描检查后,对比组的相关统计结果均优于研究1组与研究2组,其中研究1组与研究2组的左室FD均值(1.32±0.05)与(1.30±0.04)、心尖部FD最大值(1.41±0.08)与(1.39±0.07)、心远端最大FD值(1.41±0.06)与(1.31±0.05)均高于对比组的(1.22±0.02)、(1.31±0.03)、(1.27±0.02)(P<0.05)。结论为肥厚型心肌病患者使用多模式心脏磁共振扫描检查的效果较好,可了解左心室血流情况,判断有无心肌过度小梁化,为后期治疗提供参考依据。Objective To discussion on the diagnostic value of multimodal cardiac magnetic resonance in hypertrophic cardiomyopathy.Methods Fifty patients with hypertrophic cardiomyopathy admitted to the Second Affiliated Hospital of Mudanjiang Medical College from January 2020 to January 2023 were selected and divided into study group 1(with obstruction,n=21)and study group 2(without obstruction,n=29)according to whether there was left ventricular outflow tract obstruction.Twenty one healthy people who received physical examination in the Second Affiliated Hospital of Mudanjiang Medical College in the same period were selected as the control group.All participants underwent multimodal cardiac magnetic resonance examination.The differences of fractal dimension of left ventricular myocardial over trabeculation,left ventricular blood flow pattern in each cardiac cycle,and related indicators of left ventricular function between different groups were compared.Results After scanning,the relevant statistical results of the control group were better than those of the study group 1 and the study group 2.The mean value of left ventricular FD(1.32±0.05)and(1.30±0.04),the maximum value of apical FD(1.41±0.08)and(1.39±0.07),and the maximum value of distal FD(1.41±0.06)and(1.31±0.05)of the study group 1 and study group 2 were higher than those of the control group(1.22±0.02),(1.31±0.03),(1.27±0.02)(P<0.05).Conclusion The effect of multimodal cardiac magnetic resonance scanning in patients with hypertrophic cardiomyopathy is better,which can understand the left ventricular blood flow,judge whether there is excessive trabeculation of myocardium,and provide reference for later treatment.
