The presence of microvascular obstruction after ST-segment elevation acute myocardial infarction is associated with a poor outcome. The pathophysiology of this process has not been fully defined. The aim of this study was to investigate the relationship between post-reperfusion lymphopenia and microvascular obstruction. ⋯ In ST-segment elevation myocardial infarction, post-reperfusion lymphopenia is an early and powerful predictor of the presence of microvascular obstruction. The pathophysiological and therapeutic implications of this association require further study.
