中文摘要:
      目的 观察超极速脉搏波传导速度(ufPWV)技术定量评估临界性高血压成年人颈动脉形态及弹性变化的价值。方法 纳入330名接受颈动脉超声检查的成年人,根据血压分为正常组(n=159)、临界组(n=43)及高血压组(n=128)。正常组收缩压(SBP)<130 mmHg且舒张压(DBP)<80 mmHg;临界组130 mmHg ≤ SBP<140 mmHg和/或80 mmHg ≤ DBP<90 mmHg;高血压组SBP ≥ 140 mmHg或DBP ≥ 90 mmHg或正在服用降压药者。测量并比较组间颈动脉内-中膜厚度(cIMT)、收缩起始脉搏波传导速度(PWV-BS)及收缩末期脉搏波传导速度(PWV-ES),并以cIMT=0.05 cm为临界值进行亚组分析。采用Pearson相关性分析评价各参数与年龄的相关性。结果 3组间cIMT、cIMT ≥ 0.05 cm者占比、PWV-BS及PWV-ES差异均有统计学意义(P均<0.05);随血压水平升高,cIMT、cIMT ≥ 0.05 cm比例及PWV-ES均升高(P均<0.05),但仅正常组与临界组间PWV-BS差异有统计学意义(P<0.05)。cIMT ≥ 0.05 cm时,各亚组间PWV-BS差异无统计学意义(P>0.05),高血压亚组PWV-ES高于正常亚组(P<0.05);cIMT<0.05 cm时,临界亚组PWV-BS及PWV-ES均高于正常亚组(P均<0.05),高血压亚组PWV-BS低于临界亚组(P<0.05)而PWV-ES高于正常亚组(P<0.05)。cIMT、PWV-BS及PWV-ES均与年龄成正相关(r=0.64、0.33、0.69,P<0.01)。结论 临界性高血压成年人颈动脉形态及弹性已发生改变,且弹性变化可能早于形态变化。
英文摘要:
      Objective To observe the value of ultrafast ultrasound pulse wave velocity (ufPWV) technique for quantitatively evaluation on changes of carotid artery morphology and elasticity in adults with borderline hypertension. Methods A total of 330 adults who underwent carotid ultrasound were enrolled and divided into normal group (systolic blood pressure <130 mmHg and diastolic blood pressure <80 mmHg, n=159), critical group (130 mmHg ≤ SBP<140 mmHg and/or 80 mmHg ≤ DBP<90 mmHg, n=43) and hypertension group (SBP ≥ 140 mmHg or DBP ≥ 90 mmHg, or taking antihypertensive medicine, n=128) according to blood pressure. Carotid intima-media thickness (cIMT), pulse wave velocity in beginning of systole (PWV-BS) and pulse wave velocity in end of systole (PWV-ES) were measured and compared among groups. Subgroup analysis was then performed taken cIMT=0.05 cm as the critical value. Pearson correlation analysis was used to evaluate the correlations between parameters and age. Results cIMT, the proportions of cIMT ≥ 0.05 cm, PWV-BS and PWV-ES were all significantly different among 3 groups (all P<0.05). Along with the increase of blood pressure level, cIMT, the proportions of cIMT ≥ 0.05 cm and PWV-ES increased (all P<0.05). However, significant difference of PWV-BS was only detected between normal group and critical group (P<0.05). When cIMT ≥ 0.05 cm, there was no significant difference of PWV-BS among subgroups (P>0.05), and PWV-ES in hypertension subgroup was higher than that in normal subgroup (P<0.05). When cIMT<0.05 cm, PWV-BS and PWV-ES in critical subgroup were higher than those in normal subgroup (both P<0.05). PWV-BS level in hypertension subgroup was lower than that in critical subgroup and higher than that in normal subgroup (both P<0.05). cIMT, PWV-BS and PWV-ES were positively correlated with age (r=0.64, 0.33, 0.69, all P<0.01). Conclusion Changes of morphology and elasticity of carotid artery occurred in borderline hypertension adults, and elastic changes might be earlier than morphological changes.
