Predictive Tools for the Presence of Significant Coronary Artery Disease Requiring Intervention in Chronic Hemodialysis Patients

Background: Hemodialysis (HD) patients have increased cardiovascular risk. Coronary artery disease (CAD) may not typically manifest in these patients and the investigational results can be confounded by the fluctuation of body fluid and electrolytes. This study explored the accuracy of these findings in identifying CAD in HD patients.

Methods: Medical record data of all HD patients undergoing coronary angiography (CAG) at King Chulalongkorn Memorial Hospital between January 2017 and March 2021 were retrospectively reviewed as a discovery cohort to identify factors discriminating patients with and without significant CAG-established CAD. HD patients receiving CAG between April 2021 and March 2023 were assigned as a validation cohort.
