Carotid artery intima media thickness estimation is a well-established way of cardio vascular disease evaluation. The purpose of this cross-sectional study was to develop normal carotid intima media thickness percentile values for a Pakistani cohort. Data was collected at the Departments of Radiology and Family Medicine, The Aga Khan University Hospital, Karachi, from April 2014 to August 2015. High frequency ultrasound of carotid was done in 257 patients [97 male (38%), 160 female (62%)] without any known carotid artery disease. Reference ranges (90% range between 5th and 95th centiles) were constructed for each common carotid and internal carotid artery measurement and displayed in graph form. The mean difference was found in left common carotid artery (0.55 ±0.13) and left internal carotid artery thickness (0.50 ±0.10) significant at p=0.031 and p=0.014, respectively. The IMTpercentile graphs developed in this study for internal and common carotid arteries are exclusive for this population and can be used to assess vascular health from ultrasound measurements.
颈动脉内膜中层厚度评估是一种成熟的心血管疾病评估方法。这项横断面研究的目的是为巴基斯坦人群制定正常的颈动脉内膜中层厚度百分位数。2014年4月至2015年8月期间，在卡拉奇阿迦汗大学医院放射科和家庭医学科收集数据。对257例无已知颈动脉疾病的患者[97例男性（38%），160例女性（62%）]进行了颈动脉高频超声检查。为每个颈总动脉和颈内动脉测量构建了参考范围（第5至第95百分位数之间的90%范围），并以图表形式显示。发现左颈总动脉（0.55±0.13）和左颈内动脉厚度（0.50±0.10）的平均差异分别在p=0.031和p=0.014时具有统计学意义。本研究中为颈内动脉和颈总动脉绘制的IMT百分位数图表仅适用于该人群，可用于通过超声测量评估血管健康状况。
