Why the study?
Does the presence of aortic artery calcification or cardiac valve calcification predict mortality in maintenance hemodialysis patients?

Follow-up
42 months
Key result
The presence of aortic artery calcification was independently associated with an increased risk of all-cause mortality (HR 3.149) in maintenance hemodialysis patients.

May flag higher-risk hemodialysis patients for monitoring; leaves open whether modifying calcification improves outcomes.

Does the presence of aortic artery calcification or cardiac valve calcification predict mortality in maintenance hemodialysis patients?
Hazard Ratio: 3.149 (95% CI 0.889–11.159)
p-value: p=0.025
Lateral lumbar X-ray and echocardiography are simple methods to detect aortic and cardiac valve calcification, which independently predict all-cause and cardiovascular mortality in maintenance hemodialysis patients.
Chen et al. (2015) conducted a cohort in Maintenance hemodialysis (n=110). Aortic artery calcification (AAC) vs. Absence of AAC was evaluated on All-cause mortality (HR 3.149, 95% CI 0.889-11.159, p=0.025). The presence of aortic artery calcification was independently associated with an increased risk of all-cause mortality (HR 3.149) in maintenance hemodialysis patients.
