Risk stratification for the development of SAHREs has never been investigated. We aimed to assess the performance of the C\n 2<\/jats:sub>\n HEST (coronary artery disease or chronic obstructive pulmonary disease [1 point each], hypertension [1 point], elderly [age \u226575\u00a0years, 2 points], systolic heart failure [2 points], thyroid disease [1 point]) score in predicting SAHREs in patients with cardiac implantable electronic devices without atrial fibrillation.\n <\/jats:p>\n <\/jats:sec>\n \n Methods and Results<\/jats:title>\n \n Five Hundred consecutive patients with cardiac implantable electronic devices in the West Birmingham Atrial Fibrillation Project in the United Kingdom were followed since the procedure to observe the development of SAHREs, defined by atrial high\u2010rate episodes lasting >24\u00a0hours. Risk factors and incidence of SAHREs were analyzed. The predictive value of the C\n 2<\/jats:sub>\n HEST score for SAHRE prediction was evaluated. Over a mean follow\u2010up of 53.1\u00a0months, 44 (8.8%) patients developed SAHREs. SAHREs were associated with higher all\u2010cause mortality (\n P<\/jats:italic>\n <0.001) and ischemic stroke (\n P<\/jats:italic>\n =0.001). Age and heart failure were associated with SAHRE occurrence. The incidence of SAHREs increased by the C\n 2<\/jats:sub>\n HEST score (39% higher risk per point increase). Among patients with a C\n 2<\/jats:sub>\n HEST score \u22654, the incidence of SAHREs was 3.62% per year (95% CI, 2.14\u20135.16). The C\n 2<\/jats:sub>\n HEST score had moderate predictive capability (area under the curve, 0.73; 95% CI, 0.64\u20130.81) and discriminative ability (log\u2010rank\n P<\/jats:italic>\n =0.003), which was better than other clinical scores (CHA\n 2<\/jats:sub>\n DS\n 2<\/jats:sub>\n \u2010VASc, CHADS\n 2<\/jats:sub>\n , HATCH).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n The C\n 2<\/jats:sub>\n HEST score predicted SAHRE incidence in patients without atrial fibrillation who had an cardiac implantable electronic device, with the highest risk seen in patients with a C\n 2<\/jats:sub>\n HEST score \u22654 The benefit of using the C\n 2<\/jats:sub>\n HEST score in clinical practice in this patient population needs further investigation.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1161\/jaha.120.017519","type":"journal-article","created":{"date-parts":[[2021,3,5]],"date-time":"2021-03-05T06:15:41Z","timestamp":1614924941000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":17,"title":["Identifying At\u2010Risk Patients for Sustained Atrial High\u2010Rate Episodes Using the C\n 2<\/sub>\n HEST Score: The West Birmingham Atrial Fibrillation Project"],"prefix":"10.1161","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9121-1887","authenticated-orcid":false,"given":"Yan\u2010Guang","family":"Li","sequence":"first","affiliation":[{"name":"Liverpool Centre for Cardiovascular Science University of Liverpool and Liverpool Heart & Chest Hospital Liverpool United Kingdom"},{"name":"Department of Cardiology and Institute of Vascular Medicine Peking University Third Hospital Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6357-5213","authenticated-orcid":false,"given":"Daniele","family":"Pastori","sequence":"additional","affiliation":[{"name":"Emergency Medicine Unit Department of Clinical Internal Anesthesiological and Cardiovascular Sciences Sapienza University Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuo","family":"Miyazawa","sequence":"additional","affiliation":[{"name":"Liverpool Centre for Cardiovascular Science University of Liverpool and Liverpool Heart & Chest Hospital Liverpool United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farhan","family":"Shahid","sequence":"additional","affiliation":[{"name":"Liverpool Centre for Cardiovascular Science University of Liverpool and Liverpool Heart & Chest Hospital Liverpool United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7566-1626","authenticated-orcid":false,"given":"Gregory Y.
