Abstract
Chronic renal failure is associated with significantly increased morbidity and
mortality. It affects almost every system of the body and results in various functional and
structural abnormalities.
Cardiovascular disease is one of the leading causes of mortality in chronic renal
failure patients.
In hemodialysis patients, arteriovenous fistula causes a left-to-right shunt leading to
chronic volume overload and increasing the risk of pulmonary hypertension.
Most of the available studies focused on left ventricular function in dialysis patients,
but the impact of dialysis on the development of right ventricular dysfunction has not fully
been investigated.
The aim of the present study was to assess the right ventricular function in
hemodialysis patients using echocardiography (2D, TDI and speckle tracking) modalities.
The present study was conducted in Cardiology department, Faculty of Medicine,
Menoufia University Hospital during the period from October 2018 to October 2019 on 70
subjects grouped as follows:
group I: 50 patients on hemodialysis.
group II: 20 healthy subjects, age and sex matched as control group.
In the present study, all participants were subjected to complete history taking, full
clinical examination, ECG and assessment of cardiac functions using conventional, tissue
Doppler and speckle tracking echocardiography.
2D echocardiography was used to assess all cardiac valves to exclude the presence of
any organic affection, and to assess wall motion abnormalities, detect rheumatic and
congenital heart diseases, assess RVSP, SPAP and FAC.
M-mode echocardiography was used to assess aortic & left atrial diameters,
interventricular septum thickness during diastole & systole, posterior wall thickness in
diastole & systole, left ventricular end-diastolic diameter, left ventricular end-systolic
diameter, fractional shortening, LV ejection fraction, and tricuspid annular plane systolic
excursion.
Tissue Doppler imaging was used to assess annular peak systolic velocity, early and
late peak annular diastolic velocities.
Speckle tracking echocardiography was used to assess RV peak systolic longitudinal
strain and strain rate, RV peak early diastolic longitudinal strain rate, and RV peak late
diastolic longitudinal strain rate.
In the present study there was no statistically significant difference between the two groups regarding age and sex.
