Prognostic significance of preprocedural troponin-I in patients with non-ST elevation acute coronary syndromes undergoing percutaneous coronary intervention.

Objective: Cardiac troponin elevation has been shown to be associated with adverse outcomes after percutaneous coronary intervention (PCI) for various subgroups of coronary artery disease. We sought to determine the prognostic significance of cardiac troponin I (cTnI) in patients with non-ST-elevation acute coronary syndromes (NSTE-ACS) treated with PCI.

Methods: The study consisted of 760 consecutive patients undergoing PCI for NSTE-ACS.
