Study of Left Ventricular Diastolic Function in Essential hypertensive patients-By comparison between Mitral Doppler flow and D.pdf

1、Objective:The assessment of diastolic function is very important in order to get information relevant to patient functional class,management and diagnosis,It will also guides the clinicain to understand the situation of

2、the cardiac problem.If diastolic function is correctly assessed and manage at early time it can reduce the risk for subsequent cardiovascular morbid events.Therefore the purpose of this study is to evaluate myocardial fu

3、nction of our hypertensive patients with echocardiography and to contrast characteristics of parameters of conventional Doppler mitral flow and Doppler tissue imaging,and analyzing whether the degree of diastolic dysfunc

4、tion is related to variant grade of hypertension.Conclusion:1.Impaired LV myocardial relaxation emerges early than damage contraction or may be the only presentation of myocardial dysfunction in patients with hyperteniso

5、n.2.Mitral blood flow Early/late(MV-E/A ratio) is still a conventional useful index to detect diastolic dysfunction.3.Peak E velocity and E/A of mitral blood flow,inner and outer annulus decrease in hypertensive patients

6、 and decrease with age.4.Mitral flow E/A ratio correlates well with annulus E/A,suggesting intrinsic relaxation exist between myocardial and chamber complicnace.5.The DTI parameter are different at inner and outer annulu

7、s,systolic and diastolic velocity and E/A measured,at outer are greater that at inner.6.DTI is a promising non-invasive technique to evaluate myocardial relaxation,annulus diastolic velocity and E/A ratio are more useful
