Abstract

Background: A mild and asymptomatic increase in the troponin level following elective percutaneous coronary interventions (PCI) has been widely reported, however, the prognostic role of this finding has not yet been well established.
Aim: To assess prognostic value of troponin I level increase following elective PCI.
Methods: The study group consisted of 90 consecutive patients who underwent elective PCI in our institution. Troponin I level (normal values <0.1 ug/L) was assessed at baseline and 12 as well as 24 hours after the procedure. In addition, CK-MB level was measured 12 and 24 hours following PCI. Left ventricular (LV) systolic performance was assessed echocardiographically at baseline and after 12 months. The incidence of major adverse coronary events (MACE) during one-year follow-up was also evaluated.
Results: 1.0 ug/L) increase of troponin I, with a concomitant significant elevation of the CK-MB level. Patients with a positive troponin test developed systolic LV abnormalities more often than patients with a normal troponin I level following PCI (p<0.001). There were 10 MACE in the troponin-positive group and 2 in the troponin-negative patients (NS). Seven MACE occurred in patients with marked increase in troponin I level (>1.0 ug/L) which was significantly more often than in the troponin-negative patients (p<0.001).
Conclusions: 1.0 ug/L) increase in troponin I level identified patients at risk of MACE. An increase in troponin I level was similar following various types of PCI.
