对于有些高血压病人,左室肥厚究系长期高血压的继发性后果抑或并存的原发性肥厚型心肌病的表现,殊难判断。为此,也为了进一步阐明高血压病人左室肥厚的特点,作者采用二维超声心动图,以102例血压长期增高伴左室壁明显增厚的病人为对象,试析左室肥厚的类型。病人平均61(31～88)岁,女性占58%,全为黑人。经选择,每例病人在室间隔前段、室间隔后段、前外游离壁和后游离壁共4个节段中,至少一个节段厚度>15mm,范围为16～29mm。依照肥厚的分布分成:A 组67例(66%)对称性肥厚;B 组35例(34%)非对称性肥厚。非对称性肥厚指左室壁至少一个节段厚度与另一节段厚度之比≥1.5。B 组非对称性肥厚的分布,大致符合肥厚型心肌病的特点。其中
For some patients with hypertension, left ventricular hypertrophy is secondary to the long-term consequences of hypertension or coexisting with primary hypertrophic cardiomyopathy, the performance is difficult to judge. To this end, but also to further clarify the characteristics of hypertensive patients with left ventricular hypertrophy, the authors used two-dimensional echocardiography to 102 patients with long-term blood pressure increased left ventricular wall thickening of patients as the object, to analyze the type of left ventricular hypertrophy. The average patient 61 (31 to 88) years old, women accounted for 58%, all black. Each patient was selected to have a thickness of> 15 mm and a range of 16-29 mm out of four segments of anterior segment, posterior segment, anterolateral free wall, and posterior free segment in each patient. According to the distribution of hypertrophy divided into: A group of 67 patients (66%) symmetrical hypertrophy; B group 35 cases (34%) asymmetric hypertrophy. Asymmetric hypertrophy refers to the ratio of the thickness of at least one segment of the LV wall to the thickness of the other segment ≥ 1.5. B group asymmetric distribution of hypertrophy, broadly consistent with the characteristics of hypertrophic cardiomyopathy. among them
