Abstract

Background: Coronary artery disease (CAD) increases the risk of both short-term and long-term mortality in patients with end-stage chronic kidney disease who have not or have received renal replacement therapy. The rate of CAD in dialysis patients is high, estimated at 40-50%⁶. Unfortunately, it is difficult to reduce the mortality rate from CAD in chronic hemodialysis patients because the lesions are complicated. Objectives: To evaluate the characteristics of coronary artery lesions in chronic hemodialysis patients received coronary angiography. Methods: A retrospective descriptive cross-sectional study was conducted on chronic hemodialysis patients received coronary angiography at the Interventional Cardiology Department, Nguyen Tri Phuong Hospital. Results: Retrospective study of 6-year from October 2016 to the end of September 2022 recorded 67 cases of chronic hemodialysis patients received coronary angiography. The rate of multi-vessels lesions in the study was 67.3%, the rate of diffuse lesions (>2cm) was 74.6%. There are 56.7% of type C coronary artery lesions according to the classification of the American Heart Association/American College of Cardiology (AHA/ACC). The rate of coronary artery calcification is 70.2%. The short-term mortality rate within 30 days after coronary angiography in the groups with and without coronary artery intervention was 15.2% and 14.3%, respectively, with no difference, p>0.05. Conclusions: Most coronary artery lesions in chronic hemodialysis patients are multi-vessels, calcified, diffuse and complicated. The short-term outcome of chronic hemodialysis patients associated with CAD is poor, with a high risk of death.
