脉压/心脏每搏输出量(pulse pressure/stroke volume indexed,PP/SVI)与身高2.04的比值是判断动脉硬化的有效指标,但其与颈动脉粥样硬化的关系尚不明确。方法 :分析坎帕尼亚地区无常见心血管疾病高血压患者2609例的临床超声心电图和颈动脉超声检查资料。按照PP/SVI将研究人群进行三分位分组。应用颈动脉超声检测颈总和颈内动脉内膜中层厚度(intima-mediathickness,IMT)的峰值、平均水平以及是否存在颈动脉粥样硬化斑块。结果 :随着PP/SVI三分位的增加,患者年龄、血压、血清总胆固醇以及抗高血压药物的数量
The ratio of pulse pressure / stroke volume indexed (PP / SVI) to height 2.04 is an effective measure of atherosclerosis, but its relationship with carotid atherosclerosis is not yet clear. Methods: Clinical echocardiography and carotid ultrasonography were performed in 2609 patients with uncomplicated cardiovascular disease in Campania. The study population was divided into tertiles according to PP / SVI. Carotid ultrasonography was used to detect the peak and average levels of the total neck and internal carotid artery intima-media thickness (IMT) and the presence of carotid atherosclerotic plaque. Results: With the increase of PP / SVI tertile, patient’s age, blood pressure, serum total cholesterol and antihypertensive drugs
