Impact of periprocedural biomarker elevation on mortality in stable angina pectoris patients undergoing elective coronary intervention: a systematic review and meta-analysis including 24 666 patients.

Uncertainty remains regarding the exact prognostic impact of biomarker elevation following percutaneous coronary intervention in patients with stable angina pectoris and the subsequent risk of death. We sought, therefore, to evaluate the effect of periprocedural myocardial infarction on the subsequent mortality risk following percutaneous coronary intervention in patients with stable angina pectoris and normal preprocedural cardiac biomarkers level.
