Post-procedural elevated cardiac troponin I and the association with 5-year mortality in patients undergoing elective PCI.

ABSTRACT:

Background

The clinically meaningful cardiac troponin I (cTnI) threshold associated with the long-term prognosis in patients undergoing elective percutaneous coronary intervention (PCI) is still debated.

Objective

To assess the association between different thresholds for post-procedural cTnI and 5-year mortality.

Methods

The study included 4059 consecutive patients with normal baseline cTnI values who underwent elective PCI. The post-procedural cTnI level was measured at 8-48 h after PCI. The main study endpoints were 5-year all-cause mortality and cardiovascular mortality.

Results

A cTnI ≥5 times the upper reference limit (URL) as defined by the fourth universal definition of myocardial infarction (4th UDMI), ≥35 times as defined by the Academic Research Cons
