Summary
This study found elevated levels of 10 trace elements, including cobalt, in the heart tissue of uremic patients. These findings suggest that excess trace elements may contribute to uremic heart failure.
Area of Science:
- Nephrology
- Cardiology
- Toxicology
Background:
- Uremic heart failure is a significant complication in patients with kidney disease.
- The role of trace element accumulation in the pathogenesis of uremic cardiomyopathy is not fully understood.
Purpose of the Study:
- To investigate the concentrations of 23 trace elements in the heart tissue of uremic patients.
- To compare these concentrations with those in non-uremic individuals.
- To explore the potential link between elevated trace elements and uremic heart failure.
Main Methods:
- Postmortem study involving 8 uremic patients and a control group.
- Neutron activation analysis was used to determine trace element concentrations in heart tissue.
Main Results:
- Significantly increased concentrations of 10 trace elements were observed in the heart tissue of uremic patients compared to controls.
- Cobalt (Co) showed a highly significant increase (p < 0.001).
- Other elements with significant increases included Arsenic (As), Bromine (Br), Cerium (Ce), Lanthanum (La), Antimony (Sb), Scandium (Sc), Iron (Fe), Potassium (K), and Phosphorus (P).
Conclusions:
- The accumulation of certain trace elements, notably cobalt, in heart tissue is associated with uremia.
- These elevated trace elements, particularly cardiotoxic ones like cobalt, may play an etiological role in the development of uremic heart failure.
