摘　　要：目的评价门控心肌灌注显像技术对扩张型心肌病(DCM)患者的诊断价值。方法 56例心脏病患者,根据疾病类型分为研究组(DCM)和对照组[缺血性心肌病(ICM)],每组28例。两组均采用门控心肌灌注成像技术进行诊断,对比两组心肌灌注评分、心室肥大情况及心功能指标。结果研究组总负荷评分(SSS)、总静息评分(SRS)、总差值(SDS)分别为(6.10±4.60)、(4.14±2.50)、(2.78±3.02)分,均低于对照组的(11.74±5.19)、(6.29±4.03)、(4.89±4.25)分,差异有统计学意义(P<0.05)。两组左室肥大发生率比较,差异无统计学意义(P>0.05);研究组右室肥大发生率85.71%高于对照组的7.14%,差异有统计学意义(P<0.05)。研究组左室射血分数(LVEF)(25.33±6.29)%小于对照组的(40.39±9.20)%,左室舒张末期容积(EDV)(203.50±72.30)ml、左室收缩末期容积(ESV)(152.30±40.89)ml均大于对照组的(149.40±50.38)、(105.81±32.55)ml,差异有统计学意义(P<0.05)。结论不同类型心肌病患者的门控心肌灌注造影成像结果差异明显, ICM患者的成像以左室增大为主,放射状分布疏松、散状,而DCM患者的双室均有肥大,斑点状放射分布。Objective To evaluate the diagnostic value of gated myocardial perfusion imaging on patients with dilated cardiomyopathy.Methods A total of 56 patients with heart disease were divided into study group(DCM)and control group[ischemic cardiomyopathy(ICM)]according to types of disease,with 28 cases in each group.Both groups were diagnosed with gated myocardial perfusion imaging technology,and the myocardial perfusion score,ventricular hypertrophy and cardiac function indexes were compared between the two groups.Results The summed stress score(SSS),summed rest score(SRS)and summed difference score(SDS)of the research group were(6.10±4.60),(4.14±2.50)and(2.78±3.02)points,which were all lower than(11.74±5.19),(6.29±4.03)and(4.89±4.25)points of the control group,and the difference was statistically significant(P<0.05).There was no statistically significant difference in incidence of left ventricular hypertrophy between the two groups(P>0.05).The incidence of right ventricular hypertrophy 85.71%of the research group was higher than 7.14%of the control group,and the difference was statistically significant(P<0.05).The left ventricular ejection fraction(LVEF)(25.33±6.29)%of the research group was less than(40.39±9.20)%of the control group,left ventricular end diastolic volume(EDV)(203.50±72.30)ml and left ventricular end systolic volume(ESV)(152.30±40.89)ml were significantly higher than(149.40±50.38)ml and(105.81±32.55)ml of the control group,and the differences was statistically significant(P<0.05).Conclusion The results of gated myocardial perfusion imaging of patients with different types of cardiomyopathy are significantly different.The imaging of ICM patients is mainly left ventricular enlargement,with loose and scattered radial distribution,while the double chambers of DCM have hypertrophy and spotted radiation distribution.
