Chest pain: if it hurts a lot, is heart attack more likely?
Pain score has limited diagnostic value for AMI. Scores should guide analgesia but shift the probability of AMI very little, and should not guide other clinical management.
C1q testing in pretransplant sera with DSA was unable to predict acute antibody-mediated rejection or early graft loss, but the presence of DSA class I compared to DSA only class II did. Despite non-fixing complement in vitro, pretransplant C1q-negative DSA I can mediate rejection and graft loss.
