作者采用前瞻性的研究方法,对一组老年对象进行随访观察,目的是了解颈总动脉管径及其与临床表现的关系。 作者从4个社区选择5201名65岁以上的老年对象(2259名男性,平均年龄73.3±5.8岁;2942名女性,平均年龄72.4±5.4岁),测量其血压、身高和体重。采用2.5MHz及3.5MHz探头进行超声心动图检查及M型二维多普勒速度测定,以估价左心室容积(LV)。在颈前内侧颈动脉窦近侧1cm处用高分辨率 The authors used a prospective study to follow up a group of elderly subjects for the purpose of understanding the common carotid artery diameter and its relationship with clinical manifestations. The authors selected 5201 elderly subjects 65 years of age and older (2259 males, mean age 73.3 ± 5.8 years; 2942 females, mean age 72.4 ± 5.4 years) from 4 communities and measured their blood pressure, height and weight. Echocardiography and M-mode 2D Doppler velocimetry were performed using 2.5 MHz and 3.5 MHz probes to assess left ventricular volume (LV).
