概要	Background: The gender difference in long-term clinical prognosis after percutaneous coronary intervention (PCI) with rotational atherectomy (RA) against severe calcified coronary artery is totally unclear in the drug-eluting stent (DES) era.Methods: This is the subanalysis of J2T-ROTA registry that included 1,090 patients undergoing PCI with RA at three hospitals between 2004 and 2014. After the exclusion of patients receiving regular hemodialysis, 788 patients including 570 males and 218 females were finally analyzed. The primary endpoint was major adverse cardiovascular event (MACE) including any death, acute coronary syndrome (ACS) and stroke. Results: Female patients were significantly older, and frequently had chronic kidney disease, presentation of ACS, atrial fibrillation (AF), lower body mass index, poorer lipid profiles and higher levels of C-reactive protein and brain natriuretic peptide than male. Kaplan-Meier analysis showed a significantly higher MACE rate in female (Log-rank: p=0.019) during 1,492 days of median observational period. Multivariate Cox regression analysis revealed that age, comorbidity of AF and values of left ventricular ejection fraction were independent predictors for MACE (HR: 1.07 [95%CI: 1.03-1.11]; HR: 1.91 [95%CI: 1.05-3.50]; HR: 0.95 [95%CI: 0.93-0.97], respectively). However, female gender was not independently associated with MACE.
