Cornell指数对高血压病患者左室构型的诊断价值

Value of Cornell index in diagnosis of left ventricular hypertrophy in patients with essential hypertension

摘要

摘要: 目的: 观察心电图Cornell指数对高血压病左室肥厚以及左室肥厚不同几何构型的诊断价值。方法：选用本院住院以及门诊高血压病患者96（男50，女46）例，年龄（54±14）岁。根据心脏超声检查的结果，将入选患者分为4组：①正常几何形态（normal geometry,N）；②向心性重构（concentric remodeling,CR）；③向心性肥厚（concentric hypertrophy,CH）；④离心性肥厚（eccentric hypertrophy,EH），观察心电图Cornell指数在各组中的阳性率。结果： Cornell指数均能明显区分正常心脏形态及左心室肥厚；在不同左室肥厚构型中，Cornell电压指数>2.8 mV（男）和Cornell电压指数>2.0 mV（女）以及Cornell乘积指数>2 440 mm/ms能够显著区分CH（阳性率分别为88%、85%和82%）和EH（阳性率分别为62%、60%和62%）（P<0.01）；Cornell乘积指数>2 440 mm/ms（在CR组的阳性率（80%、75%）明显高于EH组（62%、40%）（P<0.01）。结论：心电图Cornell电压指数及Cornell乘积指数可较好鉴别高血压病左室肥厚的不同几何构型。

Abstract: AIM: To assess the diagnostic values of Cornell indexes in diagnosis of left ventricular hypertrophy (LVH) and in detecting different geometric patterns of hypertrophy in patients with essential hypertension. METHODS: Ninety-six patients with essential hypertension were divided into four groups according to the different parameters of echocardiography such as left ventricular mass index and relative wall thickness: normal geometry group (N), concentric remodeling group (CR), concentric hypertrophy group (CH) and eccentric hypertrophy group (EH). Cornell indexes in different groups were analyzed. RESULTS: Cornell voltage index and Cornell product index differentiated LVH from normal geometry. Cornell voltage index >2.8 mv (male), Cornell voltage index >2.0 mv (female) and Cornell product index >2 440 mm/msec (male) were of great value in discriminating CH (88.2%, 84.6% and 82.4%) and EH (62.5%, 60.0% and 62.5%) (P<0.01). Cornell product index >2 440 mm/msec (male and female) was significantly higher in the CR group (80.0%, 75.0%) compared with that in the EH group (62.5%, 40.0%) (P<0.01). CONCLUSION: Cornell voltage index and Cornell product index have significant values in discriminating different geometric patterns of LVH.
