摘　　要：目的探讨心脏磁共振成像在肥厚型心肌病中的应用价值。方法选取2019年5月—2023年2月南京市江宁医院收治的肥厚型心肌病患者47例作为肥厚型心肌病组,并取同时期接受体检的健康者46例作为对照组,均接受心脏磁共振成像检查。比较两组心脏磁共振成像检查指标以及典型心尖肥厚型心肌病与早期心尖肥厚型心肌病患者心脏磁共振成像检查指标。结果肥厚型心肌病组患者的左心房前后径,室间隔、前壁、侧壁、下壁与心尖部室壁的厚度均高于对照组,差异有统计学意义(P<0.05)。肥厚型心肌病组左心室射血分数为(62.65±3.68)%,低于对照组的(66.35±3.25)%,差异有统计学意义(t=5.135,P<0.05)。典型心尖肥厚型心肌病组的心尖部室壁厚度、左心房前后径均高于早期心尖肥厚型心肌病组,左心室射血分数低于早期心尖肥厚型心肌病组,差异有统计学意义(P<0.05)。结论心脏磁共振成像的应用,可有效检测肥厚型心肌病患者的心脏结构改变,为病变程度评估提供依据。Objective To investigate the application value of cardiac magnetic resonance imaging in hypertrophic cardiomyopathy.Methods 47 patients with hypertrophic cardiomyopathy admitted to Jiangning Hospital in Nanjing from May 2019 to February 2023 were selected as the hypertrophic cardiomyopathy group,and 46 healthy individuals who underwent physical examination during the same period were selected as the control group,all of whom underwent cardiac magnetic resonance imaging examination.Compared the cardiac magnetic resonance imaging examination indicators between two groups,as well as the cardiac magnetic resonance imaging examination indicators of patients with typical apical hypertrophic cardiomyopathy and early apical hypertrophic cardiomyopathy.Results The anterior and posterior diameter of left atrium,the thickness of ventricular septum,anterior wall,lateral wall,inferior wall and apical wall in hypertrophic cardiomyopathy group were higher than those in control group,and the difference was statistically significant(P<0.05).The left ventricular Ejection fraction(LVEF)of patients with hypertrophic cardiomyopathy was(62.65±3.68)%,which was significantly lower than that of the control group(66.35±3.25)%,the difference was statistically significant(t=5.135,P<0.05).The apical wall thickness and anterior and posterior diameter of the left atrium in the typical apical hypertrophic cardiomyopathy group were higher than those in the early apical hypertrophic cardiomyopathy group,and the left ventricular ejection fraction was lower than that in the early apical hypertrophic cardiomyopathy group the difference was statistically significant(P<0.05).Conclusion The application of cardiac magnetic resonance imaging can effectively detect the cardiac structural changes in patients with hypertrophic cardiomyopathy,and provide a basis for the assessment of the degree of lesion.
