Background: Periprocedural myocardial infarction (PMI) occurs more
frequently in patients with heavily calcified lesion and undergoing rotational
atherectomy (RA). However, there are limited studies addressing prognostic impact
of PMI in patients requiring RA due to severe coronary artery calcification
(CAC). Therefore, the objective of this study was to determine the prognostic
impact of PMI in patients who underwent percutaneous coronary intervention (PCI)
using RA. Methods: A total of 540 patients (583 lesions) who received
PCI using RA were enrolled between January 2010 and October 2019. PMI was defined
as elevations of creatine kinase-myocardial band (CK-MB)
