摘要
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 4 8.1%、4 8.7%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 0 1)。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 0 5 )。结论 %PLM识别左室重构比LVMI更符合生理情况 。
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.
