Introduction: The prognostic value of troponin elevation following elective PCI in the modern era is uncertain, and many centers no longer monitor troponin level post PCI. We examined the association between post-PCI troponin elevations in patients with stable angina undergoing elective PCI and long-term survival.
Methods: We reviewed 1709 elective PCI cases performed at Dartmouth Hitchcock Medical Center between 2006 and 2015. All patients had serial troponin T levels measured for 18-24 hours. Post-procedure troponin values were stratified by both the National cardiovascular data registry (NCDR) definition of procedural MI (troponin >0.09) and the Joint Task Force (JTF) definition (troponin >0.15). Post PCI in-hospital events and long-term mortality data was obtained. The Fisher's Exact Test was used to compare in-hospital events and mortality rates between patients with and without troponin elevation.
Results: Average age was 65, with 23% women. Long-term mortality was statistically higher in patients with NCDR definition (24.1% vs. 15.9%, p<0.05) or JTF definition (25.3% vs. 16.3%, p<0.05) of procedural MI. In-hospital events were more common in those with troponin elevation using both definitions (19.0% vs 7.5%, p<0.05; 27.3% vs 7.5%, p<0.05).
Conclusions: Troponin elevations in patients with stable angina undergoing elective PCI are rare but predictive of both in-hospital adverse outcomes and long-term mortality. Consideration should be given to routine troponin measurement post-PCI.
