Abstract

Abstract:

Objective

To investigate the relationship of the left ventricular diastolic function and pulmonary artery hypertension(PAH)in the maintenance hemodialysis(MHD)patients.

Methods

From March 2014 to June 2015, 53 cases of MHD patients with PAH and 83 cases of MHD patients without PAH were selected in Jinan Military General Hospital.Six hours after hemodialysis, left ventricular ejection fraction(LVEF), mitral E peak and A peak ratio(E/A)of all patients were obtained by conventional echocardiography.The maximum left atrial volume(LAVm)was obtained by the left atrial volume tracking technique(LAVT). The average values of left ventricular wall systolic peak strain rate, early diastolic peak strain rate, late diastolic peak strain rate(mSRs, mSRe, mSRa)were obtained by speckle tracking technique(STI), and mSRe/mSRa was calculated.All the data were compared between the two groups using t test, and P value of<0.05 was considered statistically significant.

Results

There were no statistically significant differences in reflecting the left ventricular systolic function indexes LVEF and mSRs between the two groups(P>0.05). The difference of LAVmax between the two groups was statistically significant(P<0.05). The differences of reflecting the left ventricular diastolic function indexes E/A, mSRe, mSRe/mSRa between the two groups were statistically significant(P<0.05).

Conclusion

The impaired left ventricular diastolic function is associated with PAH in patients with MHD.
