梗阻型心肌病又称为特发性肥厚型心肌病或主动脉瓣下狭窄(IHSS).过去曾认为是一种少见病.自超声心动图作为一种无创伤性诊断心肌病的方法以来,该病的检出率有所增多,对其认识也在深化,现就诊断、治疗作一概述.梗阻性心肌病的病因不明。因1/3的患者有家族史,故有人认为可能与遗传有关.嗜铬细胞瘤及植物神经失调的患者易患本病,故又有人认为是对正常儿茶酚胺反应异常所致.主要病理生理变化为心室肌束排列极不规则,致心肌肥厚,呈不均匀性.室间隔呈块状肥厚向室腔突出,致室腔变小.因心室失去同步收缩和舒
Obstructive cardiomyopathy, also known as idiopathic hypertrophic cardiomyopathy or aortic valve stenosis (IHSS), was previously described as a rare disease Since echocardiography, a noninvasive method of diagnosing cardiomyopathy, The detection rate of the disease has increased, their understanding is also deepening, diagnosis and treatment are now made an overview of the cause of obstructive cardiomyopathy is unknown. Because one-third of patients have a family history, so some people think that may be related to genetic.Phenochromocytoma and autonomic disorders in patients susceptible to the disease, it was also considered abnormal catecholamine reaction due to the main pathophysiological changes Very irregular arrangement of ventricular muscle bundle, resulting in hypertrophy of the myocardium, showing heterogeneity. Septal hypertrophy was massive to the prominent chamber, causing the chamber to become smaller due to loss of systolic ventricular contraction and Shu
