title: Predictors and prognostic significance of troponin-I release following elective coronary angioplasty.
abstract: The objective of this study was to investigate the predictors and prognostic significance of post-procedural cardiac troponin (cTn)-I elevations in a consecutive series of patients who underwent elective percutaneous coronary intervention (PCI). cTn-I was measured in 100 patients immediately before and within 24 h after the elective PCI. Post-procedural cTn-I elevation was observed in 27 of the 100 patients. In multivariate analysis, basal haemoglobin values and the number of repeated balloon dilatations were found to be independent predictors of cTn-I elevation. During the follow-up period of 12 +/- 1.2 months, the cTn-I-positive group had more major adverse cardiovascular events than the cTn-I-negative group (33.3% versus 16.4%, respectively), but the difference was not significant. An increase in cTn-I levels following elective PCI procedures was frequent but did not predict a poor long-term outcome.
