We quantified radial artery atherosclerosis by intravascular ultrasound (IVUS) and determined the relationship between established cardiovascular risk factors and the extent of atherosclerotic plaque. Intravascular ultrasound examination of the radial artery was performed in patients undergoing transradial angiography or intervention. Total 50-mm segments starting at the radioulnar bifurcation were analyzed at 2-mm intervals to compute atheroma volume. In 115 consecutive patients, atheroma volume averaged 67.4 mm(3) and percentage atheroma volume was 25.2%. Radial arteries showed age-related acceleration of atherosclerosis. Total atheroma volume was strongly associated with square of age and male gender. Hypertension and diabetes were strong independent predictors of larger radial artery atheroma burden. Radial artery atherosclerosis, which can be quantitatively analyzed by IVUS, could be used as a surrogate marker for atherosclerosis.
我们通过血管内超声（IVUS）定量评估了桡动脉粥样硬化，并确定了已确立的心血管危险因素与粥样斑块程度之间的关系。在接受经桡动脉血管造影或介入治疗的患者中进行了桡动脉血管内超声检查。从桡尺动脉分叉处开始，以 2mm 为间隔对全长 50mm 的节段进行分析，以计算动脉粥样斑块体积。在 115 例连续患者中，平均动脉粥样斑块体积为 67.4mm³，动脉粥样斑块体积百分比为 25.2%。桡动脉的粥样硬化与年龄呈正相关。总动脉粥样斑块体积与年龄的平方和男性性别密切相关。高血压和糖尿病是桡动脉粥样硬化斑块负担增加的强独立预测因素。通过 IVUS 可定量分析的桡动脉粥样硬化可作为动脉粥样硬化的替代标志物。
