Relationship Between Preprocedural Lipid Levels and Periprocedural Myocardial Injury in Patients Undergoing Elective Percutaneous Coronary Intervention.

Background: Periprocedural myocardial injury is a predictor of cardiovascular morbidity and mortality after percutaneous coronary intervention.

Methods: The authors examined the effects of preprocedural lipid levels (low-density lipoprotein, high-density lipoprotein, and triglycerides) in 977 patients with coronary artery disease who underwent elective percutaneous coronary intervention.

Results: Elevated cardiac troponin I level (≥5× the upper limit of normal) was used to indicate periprocedural myocardial injury.
