Background: Hemodialysis is the process of cleaning blood outside the body, involves taking
blood from a blood vessel and passing it through a synthetic filter, known as a dialyzer.
Intradialytic hypertension (IDH) is a phenomenon where blood pressure increases during
hemodialysis ,and associated with increased mortality in hemodialysis patients. Majority of
patients with IDH suffer and die from cardiovascular complications, Aim of the work : The
aim of the work is to estimate the incidence of IDH among the hemodialysis patients, and to
study myocardial functional disorders during hemodialysis in IDH patients. , Patient and
Methods: study was carried out in hemodialysis unit ,internal medicine department of Benha
University Hospital, where 100 patients were selected, Conventional echocardiography and
were done immediately before and after HD, Results: incidence of IDH was 30%. Mean
LVEDD significantly decreased post dialysis from 48.3 mm to 46.6 mm. P value was
