摘要:
目的 探讨多参数心脏磁共振（MR）对心尖肥厚型心肌病（AHCM）诊断及分型的价值。方法 选取2023年1月-2024年12月上饶市人民医院收治的70例AHCM患者作为研究组，同期健康体检人群50例作为对照组。使用西门子 MAGNETOM Skyra 3T 磁共振成像系统，对所有研究对象行心脏MR检查。比较两组及不同类型AHCM患者的左心房前后径、左心室最大横径、左心室射血分数、最大室壁厚度水平，并分析心脏MR参数对AHCM诊断及分型的价值。结果 研究组左心房前后径、左心室最大横径、左心室射血分数、最大室壁厚度均大于对照组（P＜0.05）。早期AHCM与典型AHCM患者的左心房前后径、左心室最大横径、左心室射血分数比较，差异无统计学意义（P＞0.05），而典型AHCM患者最大室壁厚度大于早期AHCM患者（P＜0.05）。单纯型与混合型AHCM患者的左心房前后径、左心室最大横径、左心室射血分数比较，差异无统计学意义（P＞0.05），而混合型AHCM患者最大室壁厚度高于单纯型患者（P＜0.05）。心脏MR参数联合诊断AHCM的曲线下面积（AUC）、敏感度、特异度、Youden指数均高于单一参数（P＜0.05），且多参数联合对不同分型AHCM患者的诊断价值亦高于单一参数（P＜0.05）。结论 多参数心脏MR对AHCM的诊断及分型具有重要价值，可为临床诊疗提供可靠依据。
Abstract:
Objective To investigate the value of multiparameter cardiac magnetic resonance (MR) in the diagnosis and classification of apical hypertrophic cardiomyopathy (AHCM). Methods A total of 70 patients with AHCM admitted to Shangrao People′s Hospital from January 2023 to December 2024 were selected as the study group, and 50 healthy people in the same period were selected as the control group. Cardiac MR examination was performed on all subjects using Siemens MAGNETOM Skyra 3T magnetic resonance imaging system. The left atrial anteroposterior diameter, left ventricular maximum transverse diameter, left ventricular ejection fraction and maximum wall thickness of the two groups and different types of AHCM patients were compared, and the value of cardiac MR parameters in the diagnosis and classification of AHCM was analyzed. Results The left atrial anteroposterior diameter, left ventricular maximum transverse diameter, left ventricular ejection fraction and maximum ventricular wall thickness in the study group were higher than those in the control group (P<0.05). There was no significant difference in left atrial anteroposterior diameter, left ventricular maximum transverse diameter and left ventricular ejection fraction between early AHCM and typical AHCM patients (P>0.05), while the maximum wall thickness of typical AHCM patients was higher than that of early AHCM patients (P<0.05). There was no significant difference in left atrial anteroposterior diameter, left ventricular maximum transverse diameter and left ventricular ejection fraction between simple and mixed AHCM patients (P>0.05), while the maximum wall thickness of mixed AHCM patients was higher than that of simple AHCM patients (P<0.05). The area under the curve (AUC), sensitivity, specificity, and Youden index of combined cardiac MR parameters for diagnosing AHCM were all higher than those of any single parameter (P<0.05), and the diagnostic value of multiparameter combination for different subtypes of AHCM was also higher than that of any single parameter (P<0.05). Conclusion Multiparameter cardiac MR is of great value in the diagnosis and classification of AHCM, which can provide a reliable basis for clinical diagnosis and treatment.
