The relationship between intradialytic hypotension and vascular calcification in hemodialysis patients.

ABSTRACT:

Background

Vascular calcification is associated with structural and functional abnormality of the heart and blood vessels. We investigated the relationship between intradialytic hypotension (IDH) and vascular calcification in hemodialysis (HD) patients, and their impacts on cardiovascular events (CVEs).

Method

We enrolled 191 maintenance HD patients who underwent plain abdomen radiography for abdominal aortic calcification score (AACS). A nadir systolic blood pressure (BP) < 90 mm Hg or the requirement of bolus fluid administration was required to quantify the hypotension diagnosis. IDH was defined as > 2 hypotension episodes during 10 HD treatments.

Results

Among the 191 patients, IDH occurred in 32. AACS was higher in the IDH group compared with the no-IDH group (8.
