문제
A patient with chronic kidney disease has a persistently elevated high-sensitivity troponin. Which approach best helps evaluate possible acute myocardial injury?
1Evaluate serial results for a significant rise or fall together with the clinical picture✓ 정답
2Interpret a single elevated value as definitive proof of acute myocardial infarction
3Replace troponin measurement with serial serum sodium levels to assess cardiac injury
4Ignore specimen quality because troponin assays are never affected by hemolysis
해설
Chronic kidney disease may be associated with stable troponin elevation. A dynamic serial change, interpreted with symptoms and other findings, is more informative for acute injury than a single value.
