目的:对高血压性肥厚性心肌病的诊断及鉴别诊断进行探讨。方法:选择符合Topol等描述特征的高血压性肥厚性心肌病10例,对其临床表现、心电图及超声心动图进行分析及治疗。结果:高血压性肥厚性心肌病临床表现及心电图无特异性,超声心动图有明显差异。结论:高血压性肥厚性心肌病不同于肥厚性心肌病和高血压性心脏病,有其不同的临床特点和治疗特殊性。 相似文献

肥厚性心肌病的治疗进展 总被引:1,自引:0,他引:1
肥厚性心肌病(hypertrophic cardiomyopathy HCM)是心源性猝死的高危因素之一。随着电生理学及分子生物学进展,对HCM有了许多新的认识,从而为HCM的防治开辟了新的途径。 1 一般措施 剧烈活动可使左室负荷增加,心肌肥厚加重,因此应限制HCM患者过度活动。另外,活动使交感神经紧张性增高,儿茶酚胺分泌增加,患者易出现严重的室性心律失常及左室流出道梗阻加重。即使是无症状的HCM患者,也应避免剧烈活动。二尖瓣返流损伤心内膜,且流出道梗阻提供了感染的基础,感染性心内膜炎又使HCM加重,应预防性使用抗生素。HCM舒张机能障碍,左心充盈压增高导致左房肥大,易出现房颤,从而形成血栓及血栓栓塞。为减少潜在的栓塞,抗凝治疗及房颤转复窦律也是必需的。 相似文献

This case study presents evidence that angioplasty and dual chamber pacing can be used as a therapeutic alternative to coronary artery bypass grafting and myectomy. The following case report describes this treatment option in a patient with hypertrophic Cardiomyopathy and ischemic heart disease who refused surgery. A severe coronary lesion was successfully treated with percutaneous transluminal coronary angioplasty (PTCA), Subsequent deterioration of the patient's clinical status occurred, yet a repeat heart catheterization revealed no angiographic changes from the PTCA. The left ventricular outflow gradient was 97 mmHg despite optimizing medical therapy. Temporary pacing leads were inserted and the patient was DDD paced at 70 ppm while measuring the LVgradient at varying A V intervals. Significant reduction of the outflow tract gradient occurred at all A V intervals tested. Although the pressure gradient decreased during VVI pacing, atrial contribution was necessary to achieve the desired hemodynamic benefit. A permanent DDDR pacemaker was implanted with satisfactory clinical results. 相似文献

Background: Hypertrophic cardiomyopathy (HCM) is one of the most common inherited cardiac disorders, with a prevalence in young adults of one in 500 and is defined by its wall thickening.
Methods: This chapter of the supplement will present major clinical impacts of this disorder in its predilection to be inherited; its reputation as the most common cause of sudden death in young, healthy, athletic individuals; and its potential to develop heart failure due to either diastolic or systolic dysfunction, so-called "burned out" HCM. Underlying etiologies; diversity of morphologic, functional, and clinical features; and variable age of onset that differentiate the childhood from the adult form of disease will be discussed based on the literature and clinical experience.
Results: In children less than 1 year of age, hypertrophy associated with systolic dysfunction is common. In contradistinction, among apparently healthy young adults, the prevalence of echcocardiographically defined HCM was reported to be as high as 0.2% and associated with diastolic dysfunction. In addition, overlaping disorders such as infiltrative and energy-dependent forms of HCM coexist with other atypical features in childhood, further confounding the presentations, treatments, and outcomes compared to adult disease.
Conclusion: HCM in childhood has a variety of etiologies which may influence diagnostic testing, treatments, and outcomes. 相似文献
