Periprocedural hemoglobin changes and myocardial injury in patients undergoing percutaneous coronary intervention.

Background: Patients undergoing percutaneous coronary intervention are at serious risk of different complications such as periprocedural bleeding that can lead to myocardial injuries. Blood loss through puncture site hematoma formation and through catheter aspiration causes periprocedural hemoglobin drop.

Objectives: Although percutaneous coronary intervention is an effective treatment of coronary artery disease, it seems necessary to investigate the impact of complications on outcomes including myocardial infarction and possible mortality.
