Post-interventional cardiac biomarker release has lower prognostic relevance compared with standard risk markers in patients with stable coronary artery disease undergoing elective percutaneous coronary interventions

摘要

The clinical relevance of post-interventional cardiac troponin release after elective percutaneous coronary interventions (PCI) in patients without overt signs of peri-interventional myocardial ischemia is still controversially discussed particularly in the field of interventional cardiology [1] despite rising the decision limit for cardiac troponins for the diagnosis of Type IVa myocardial infarction in the recent update of the universal definition of myocardial infarction to 5 times of the upper reference limit (URL) [2]. Therefore, we investigated the prognostic impact of post-interventional cardiac troponin T (cTnT) and creatine kinase (CK) release compared with established risk factors and risk markers in patients with stable coronary artery disease (CAD) undergoing elective, clinically uncomplicated PCI during long-term follow-up in a prospective cohort study.
