Different prognostic importance of elevated troponin I after percutaneous coronary intervention in acute coronary syndrome and stable angina pectoris



Different prognostic importance of elevated troponin I after percutaneous coronary intervention in acute coronary syndrome and stable angina pectoris



Scandinavian Cardiovascular Journal 42(3): 214-221



To investigate the prognostic importance of cardiac troponin I (cTnI) elevation after percutaneous coronary intervention (PCI) in different clinical settings. The study includes 238 patients presenting with acute coronary syndrome (ACS) and 194 patients with stable angina pectoris (SAP). The composite end point of death or hospitalization due to non-fatal myocardial infarction, repeated revascularization or unstable angina, was determined during one year of follow-up. cTnI elevation after PCI was more frequent in ACS patients than SAP patients. ACS patients with cTnI elevation after PCI had significantly higher number of events than patients with unchanged cTnI status after PCI. SAP patients had generally lower event rate than ACS patients. The event rate was also significantly higher among ACS patients than SAP patients at comparable degrees of cTnI elevation after PCI. There was no difference in events among SAP patients with or without cTnI elevation after PCI. cTnI elevation after PCI predicts adverse outcome after one year in patients with ACS, but not in patients with SAP.
