| 目的 探讨瞬时波强(WI)技术评估原发性高血压患者血流动力学改变的临床意义。 方法 应用WI技术对30例原发性高血压患者(高血压组)及30名正常人(对照组)的右侧颈总动脉进行检测,获得WI各参数,将两组参数进行比较。 结果 ①高血压组瞬时加速度波强(W1)和瞬时减速度波强(W2)高于对照组(P均＜0.05),高血压组瞬时波强负向波面积(NA)显著高于对照组(P＜0.01);②高血压组NA与颈动脉血流最大速度(Umax)呈正相关(r=0.66,P＜0.01),对照组NA与Umax无相关性(r=0.34,P=0.07)。 结论 WI技术是一种简单、无创的评估原发性高血压患者血流动力学改变的方法。 |

| Objective To explore the value of wave intensity (WI) technique in assessing hemodynamic alteration of patients with hypertension. Methods Right common carotid artery of 30 hypertension patients (hypertension group) and 30 healthy people (controlgroup) were examined with WI technique. WI parameters of the two groups were automatically calculated and compared. Results ①W1 and W2 in hypertension group were significantly higher than those in control group (all P＜0.05). ②NA was also considerably greater in hypertension group than that in control group (P＜0.01). There was positive correlation between NA and Umax in hypertension group (r=0.66, P＜0.01), but NA had no correlation with Umax in control group (r=0.34, P=0.07). Conclusion WI technology is a simple noninvasive means of assessing hemodynamic alteration of hypertension patients. |
