Comparison of percutaneous coronary intervention for previously treated versus de novo culprit lesions in acute myocardial infarction patients: insights from the National Cardiovascular Data Registry

Despite greater co-morbidity burden, MI patients with prior PCI had lower mortality compared with patients undergoing their first intervention. Among patients with prior PCI, patients undergoing PCI to a previously treated culprit lesion were associated with lower mortality than those being intervened for a de novo culprit. A better understanding of these differences will help improve procedural strategies and outcomes of patients undergoing PCI of a previously treated lesion.
