作者曾注意到超声心动图上左房增大可以是高血压病的唯一异常,这时候心电图或超声心动图中均无明确的左室肥厚。Dunn等曾指出高血压性心脏病左房增大可能出现于左室肥厚和/或扩张之前。另一些作者则认为左房增大仅是一个年龄一相关现象,不反映高血压引起的心脏结构改变。为此,作者分析左房增大是否高血压病人心脏负荷增加的最早征象。方法:研究对象为24例进行常规心导管检查的胸痛综合征患者,均为窦性心律,无心房颤动史,冠脉无狭窄,心室无整体或局部收缩功能不良,无二尖瓣或主动脉瓣病变,LVEDV 和 LVESV 均正常,心电图 P 波无 The authors have noted that echocardiography on left atrial enlargement can be the only abnormalities of hypertension, ECG or echocardiography at this time no clear left ventricular hypertrophy. Dunn et al have pointed out that hypertensive heart disease left atrial enlargement may occur before left ventricular hypertrophy and / or expansion. Other authors argue that increased left atrium is only an age-related phenomenon and does not reflect changes in cardiac structure caused by hypertension. To this end, the authors analyze whether left atrial enlargement is the earliest sign of increased cardiac load in hypertensive patients. Methods: Twenty-four patients with chest pain syndrome undergoing conventional cardiac catheterization were all sinus rhythm, without atrial fibrillation history, no coronary artery stenosis, no general or partial ventricular systolic dysfunction, no mitral valve or aorta Valve disease, LVEDV and LVESV were normal ECG P wave without
