Why the study?
What is the time-related diagnostic utility of total lactate dehydrogenase and its isoenzymes for detecting myocardial infarction?
What is the time-related diagnostic utility of total lactate dehydrogenase and its isoenzymes for detecting myocardial infarction?
LD-1/LD-4 and LD-1/LD-2 ratios provide the highest diagnostic utility for myocardial infarction among LD tests, with effectiveness equivalent to creatine kinase-2 but at later time intervals.
No takes yet. Share an insight, caveat, or question.
LD isoenzyme ratios may aid later MI diagnosis; leaves open their utility versus modern troponins in prospective cohorts.
Galbraith et al. (1990) studied this question.
