Abstract

Abstract:

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.
