肥厚性心肌病与高血压性左心室肥厚超声心动图对比分析

摘要

Objective The hypertrophic cardiomyopathy and hypertensive left ventricular hypertrophy Beckon-ing ultrasound results were analyzed, and the clinical features were summarized. Methods Selection of hypertrophic cardiomyopathy from April to 2014 in 2013 May in our hospital and patients with hypertensive left ventricular hyper-trophy 30 cases as LVH group and HCM group, 30 cases in healthy people for physical examination in our hospital as control group, to compare the three groups of patients with Heartbeat ultrasound graph, after analysis, three groups of ultrasound patients were analyzed and Heartbeat map between QT dispersion. Results Control group cardiac index map and QT dispersion and LVH group and HCM groups exist obvious differences and LVH group and the HCM group left ventricular myocardial weight (LVmass), interventricular septal thickness (LVST), diastolic interventricular septum thickness (LVSTd), diastolic late left ventricular posterior wall thickness (LVPWTd) and QT dispersion were lower than the control group (P<0.05), and the difference is statistically significant; LVH group and HCM groups be-tween lvmass, LVST, LVSTd / LVPWTd and QT dispersion difference significantly(P<0.05), the difference is signifi-cant. Conclusion Hypertrophic cardiomyopathy and hypertensive left ventricular hypertrophy echocardiography has obvious difference, echocardiography showed significant diagnostic value of more than two diseases, the diagnosis model is worth in the clinical practice, to reference and promotion, the other group of patients with HCM QT disper-sion is large, so in the course of treatment. Prevention efforts should be strengthened to malignant arrhythmia.%目的：探讨肥厚性心肌病与高血压性左心室肥厚超声心动图结果的异同点。方法选择2013年4月至2014年5月该院收治的肥厚性心肌病和高血压性左心室肥厚患者各30例分别作为左心室肥厚（LVH）组和非对称性室间隔肥厚（HCM）组，另选取来该院体检的30名健康人员作为对照组，对3组患者的超声心动图进行比较，分析结束后，对3组患者的超声心动图差异及QT离散度进行分析。结果对照组心动图指标与QT离散度与LVH组和HCM组差异有统计学意义，LVH组和HCM组的左室心肌重量（LVmass）、室间隔厚度（LVST）、舒张末期室间隔厚度/舒张末期左室后壁厚度（LVSTd/LVPWTd）及QT离散度均低于对照组（P＜0．05），差异具有统计学意义；LVH组和HCM组间的LVmass、LVST、LVSTd/LVPWTd及QT离散度差异有统计学意义（P＜0．05）。结论肥厚性心肌病与高血压性左心室肥厚超声心动差异有统计学意义，超声心动图对以上两种疾病具有显著的诊断价值，故该诊断模式值得在临床实践的过程中推广，另HCM组患者的QT离散度较大，故在治疗过程中，应该加强恶性心律失常的防范力度。
