左室质量比值和左室质量指数对高血压左室重构识别的比较

目的 比较左室质量比值(％PLM)和左室质量指数(LVMI)对左室重构识别的价值。方法 对187例高血压患者进行超声心动图检查，测量其心脏结构和功能。结果 左室质量适宜(aLVM)、过高(iLVM)和不足的分布分别占48.1％、48．7％和3．2％。％PLM与左室收缩功能的相关系数高于LVMI与左室收缩功能的相关系数。左室肥厚(LVH)时，iLVM的左室射血分数、左室短轴缩短率低于aLVM(P＜0．01)。但在aLVM或iLVM中．LVH和无LVH两组间的左室收缩功能无明显差异(P＞0．05)。结论 ％PLM识别左室重构比LVMI更符合生理情况，更能精确地对高血压患者进行危险分层。

The Comparison Between The Left Ventricular Mass and Left Ventricular Remodeling in Hypertensive Patients

Objective To evaluate the clinical significances of the ratio of observed/predicted left ventricular mass(%PLM) and left ventricular mass index(LVMI) in hypertensive patients. Methods Left ventricular geometry and cardiac function are assessed by echocardiography in 187 cases of essential hypertension. Results In this study, 48.1% had adequate left ventricular mass (aLVM), 48.7% inappropriately high left ventricular mass (iLVM), 3.2% inadequate left ventricular mass. Left ventricular systolic performance was related more closely with %PLM than with LVMI. Among the patients with left ventricular hypertrophy(LVH), ejection fraction(EF) and fractional shortening(FS) were lower in patients with iLVM than those in patients with aLVM( P <0 01). There was no significance in EF, FS, aLVM, iLVM between patients with LVH and witheat LVH. Conclusion Compared with LVMI, %PLM appears to reflect left ventricular remodeling more pathophysiologically which may serve an more accurate index in risk stratification in hypertensive patients.
