目的 搜集肥厚型心肌病患者心脏MRI资料,分析其受累心肌对比剂延迟强化特点.方法 应用心脏MR技术检查肥厚型心肌病患者,并行心肌对比剂延迟显像,依据9节段分析法分析受累心肌对比剂延迟强化节段范围及程度等.应用t检验对延迟与非延迟强化组数据进行统计学分析.结果 154例患者接受心肌对比剂延迟显像,其中受累心肌节段出现延迟强化的患者共95例,无延迟强化者59例.延迟与非延迟强化组受累节段厚度[分别为(24.8±5.5)和(20.4±3.8)mm,t=3.82,P<0.05]以及受累节段数[分别为(3.3±1.9)和(2.4±1.7)段,t=2.26,P<0.05]比较,前者均大于后者;而患者年龄比较,延迟强化组低于非延迟强化组[分别为(46.0±15.2)和(55.0±11.9)岁,t=-3.67,P<0.05].按照强化的形态,弥漫性强化62例,局限性强化33例.共14例患者接受了酒精消融术治疗,所有患者术后心肌延迟显像均可见明确的局限性强化影.结论 肥厚型心肌病MR对比剂延迟强化患者在受累节段厚度、数量以及年龄等各方面都明显不同于非强化患者.

Objective To analyze the characteristics of hypertrophic cardiomyopathy (HCM) on delayed contrast-enhanced cardiac magnetic resonance imaging (CMRI). Methods All patients underwent delayed contrast-enhanced CMRI. The left ventricle was divided into 9 segments to assess the location,extent and function of the hypertrophic segments. The t test was applied for the statistics. Results Of 154 patients, delayed enhancement of hypertrophic segment was found in 95 cases and non-delayed enhancement in 59 cases. The thickness and number of hypertrophic segment in patients with delayed enhancement were larger than those with non-delayed enhancement [ (24. 8 ± 5. 5 ) mm vs (20. 4 ±3.8) mm, t = 3.82, P < 0.05; (3.3 ± 1.9) vs (2.4 ± 1.7), t = 2. 26, P < 0.05 ], and the age was younger [ (46. 0 ± 15.2) years vs (55.0 ± 11.9) years, t = - 3. 67, P <0. 05 ]. The diffuse enhancement was found in 62 patients, and confluent enhancement in 33 patients. Confluent enhancement was found in all 14 patients after the alcohol ablation procedure. Conclusion The age, thickness and number of hypertrophic segments in patients with delayed enhancement are different from those with non-delayed enhancement.
