In brief

Dialysis and Heart Health: A Complicated Connection

This systematic review analyzes 28 studies to shed light on how hemodialysis impacts troponin I levels, revealing a wide range of changes that complicate AMI diagnosis in dialysis patients.

What they found: The review found that mean troponin I levels increased from 68 ng/L before dialysis to 73 ng/L afterward. Importantly, the changes in troponin levels during dialysis varied dramatically, from decreases of 100% to increases of 933%. This variability poses a significant challenge for using current AMI diagnostic guidelines in patients undergoing hemodialysis.

From the abstract

Cardiovascular disease is the leading cause of death in patients receiving hemodialysis. Current guidelines define acute myocardial infarction (AMI) by troponin levels above the 99th percentile, accompanied by a ≥ 20% rise or fall.
