The prognostic value of post-PCI troponin elevation in the modern era is uncertain. There is conflicting data as to the predictive value of the degree of troponin elevation post-PCI.
We queried Dartmouth Dynamic Registry database of consecutive PCI’s to identify elective PCI’s with documented normal troponins at baseline between 2006 and 2015. A total of 1709 cases were identified. Baseline demographic information and procedural characteristics were collected. Post procedure troponins and in-hospital adverse outcomes including heart failure, repeat intervention, arrhythmia, bleeding, and death were collected. Outcomes between patients with mild (3 times upper limit, NCDR definition) and moderate (5 times upper limit, Joint Task Force definition) troponin elevations were compared to those patients without troponin elevation to asses for predictive value. The Fishers Exact Test was used to determine statistical significance.
In patients undergoing elective PCI, even mild post-procedure troponin elevation is predictive of adverse in-hospital outcomes.
