Clinical end points were defined as the occurrence of major bleeding complications (MBC), major adverse cardiac and cerebrovascular event, and all-cause death. Among these 2648 patients, 182 (7%) patients received warfarin. After a median follow-up period of 25 months (interquartile range, 15\u201335 months), MBC had occurred in 48 (2%) patients, major adverse cardiac and cerebrovascular event in 484 (18%) patients, and all-cause death in 206 (8%) patients. Multivariable Cox regression analysis revealed that triple antithrombotic therapy was the independent predictor for the occurrence of MBC (hazard ratio, 7.25; 95% confidence interval, 3.05\u201317.21;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001). The time in therapeutic range value did not differ between the patients with and without MBC occurrence (83% [interquartile range, 50%\u201390%] versus 75% [interquartile range, 58%\u201387%];\n              <jats:italic>P<\/jats:italic>\n              =0.7). However, the mean international normalized ratio of prothrombin time at the time of MBC occurrence was 3.3\u00b12.1. Triple antithrombotic therapy did not have a predictive value for the occurrence of all-cause death (\n              <jats:italic>P<\/jats:italic>\n              =0.1) and stroke (\n              <jats:italic>P<\/jats:italic>\n              =0.2).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Triple antithrombotic therapy predisposes patients to an increased risk of MBC regardless of the time in therapeutic range.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circinterventions.113.000179","type":"journal-article","created":{"date-parts":[[2013,8,14]],"date-time":"2013-08-14T01:32:11Z","timestamp":1376443931000},"page":"444-451","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":16,"title":["Triple Antithrombotic Therapy Is the Independent Predictor for the Occurrence of Major Bleeding Complications"],"prefix":"10.1161","volume":"6","author":[{"given":"Yoshihisa","family":"Naruse","sequence":"first","affiliation":[{"name":"From the Cardiovascular Division, Faculty of Medicine, University of Tsukuba, Tsukuba, Ibaraki, Japan (Y.N., A.S., T.H., K.A.);
