Should we monitor troponin up to peak value when evaluating for acute coronary syndrome?

[摘要] No. Once the cardiac troponin concentration is higher than the 99th per centile (the upper reference limit), finding the peak value (before levels start to descend) does not help diagnose the cause of the elevation. Although the peak level has prognostic significance, continuing to follow the level after the initial set of measurements adds cost to the evaluation without providing further insight into cause, and any prognostic information gained would not change the subsequent evaluation or management, which should be driven by guidelines.
