目的

探讨超声血管回声跟踪技术(echo tracking,ET)评价吸烟者颈动脉血管弹性的应用价值,并结合吸烟者心脏结构功能探讨颈动脉弹性与心脏结构功能的相关关系。

方法

收集2014年8月至2015年8月川北医学院附属医院住院和体检男性患者,31例单纯主动吸烟患者,30例正常非吸烟者,应用ET技术检测双侧颈总动脉的收缩期最大内径(Ds)、舒张期最小内径(Dd)、弹性系数(Eρ)、僵硬度(β)、膨大指数(AI)、顺应性(AC)以及脉搏波传导速度(PWVβ)等数项指标,另外测量心脏舒张功能指标二尖瓣口脉冲频谱E/A,组织多普勒E′/A′,肺静脉S峰值/ D峰值(Vs/Vd),AR波持续时间(ARD)、左心室舒张末期内径(LVDd)、左心室心肌质量指数(LVMI)。

结果

(1)Dd、Ds、β、Eρ、AI、PWVβ单纯主动吸烟组与正常组间无统计学意义(P>0.05);(2)单纯主动吸烟组LVDd、LVMI、ARD高于正常对照组(P<0.05),E/A、E′/A′、E/E′、Vs/Vd组间均无统计学意义(P>0.05);(3)相关分析表明单纯主动吸烟组ARD与Eρ呈正相关(r=0.789,P<0.05);单纯主动吸烟组E/E′与AC呈负相关(r=-0.442),与β、Eρ、PWVβ呈正相关(r分别为0.667、0.617、0.979,P<0.05)。

结论

吸烟者动脉弹性功能与心脏舒张功能呈正相关,舒张功能随着血管弹性功能的降低而降低。

Objective

To evaluate the application value of echo tracking(ET)on carotid artery elasticity of smoking people, and combined with heart diastolic function to investigate the relation of carotid artery elasticity and left ventricle diastolic function.

Methods

The two common carotid arteries of 31 cases active smoking people and 30 cases of non smokers were detected by ET, and the maximum systolic blood vessel diameter(Ds), diastolic minimum diameter(Dd), elastic coefficient(Eρ), stifness paramet(β), swelling index(AI), compliance(AC)and pulse wave velocity(PWVβ)were measured.In addition, the cardiac diastolic function indexes such as mitral valve pulse spectrum E/A, tissue doppler E′/A′, pulmonary vein S peak/D peak(Vs/Vd), AR wave duration time(ARD), left ventricular end diastole diameter(LVDd), left ventricular mass index(LVMI).

Results

①The differences of Dd, Ds, β, Eρ, AI, PWVβbetween active smoking group and the normal group were not statistically significant(P>0.05). ②The LVDd, LVMI and ARD of active smoking group were higher than those of the normal group(P<0.05). ③The differences of E/A, E′/A′, E/E′and Vs/Vd between the two groups were not statistically significant(P>0.05). ④Correlation analysis showed that ARD had positive relation to Eρ(P<0.05), and E/E′had negative relation to AC and positive relation toβ, Eρ, PWVβ(P<0.05)in active smoking group.

Conclusion

Heart diastolic function can reflect cigarette smoking people The blood vessels elastic function of smoking people is positively correlated with heart diastolic function, and heart diastolic function decreases with the decrease of vascular elasticity.
