Fourteen patients with asynergy were investigated by H215O dynamic positron emission tomography imaging before revascularization. Regional myocardial blood flow (MBF) was determined and the water-perfusable tissue fraction (PTF) for each region of interest and the total anatomical tissue fraction (ATF) were estimated. The PTF/ATF was analyzed as the water perfusable tissue index (PTI). Asynergy was defined as segments with wall motion more than 2 SD below than that of a normal population. An increase of >0.8 SD in anterior wall segments with asynergy and an increase of >0.6 SD in inferior wall asynergy were defined as significant improvements of wall motion indicative of viable myocardium. Fifteen segments with wall motion abnormalities less than -2 SD and 10 control segments were identified; 7 segments recovered and 8 segments did not. MBF was similar in both groups of segments before revascularization (0.78±0.27 vs 0.73±0.18 ml · min-1 · g-1, NS). The PTI in the recovered segments was significantly higher than that in the unimproved segments (0.734±0.058 vs 0.592±0.038, p<0.0001) and was similar to that of the control segments. After revascularization, the PTI correlated with the SD of wall motion (p<0.05, r=0.58). PTI may be a good predictor of contractile recovery after revascularization.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院医学系研究科","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本循環器学会"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1253/circj.66.341","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jstage.jst.go.jp/article/circj/66/4/66_341/_article/-char/en","subitem_relation_type_select":"URI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11591968","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-9843","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Itoh, Hideki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Namura, Masanobu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Seki, Hiroyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Asai, Toru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsuchiya, Taketsugu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uenishi, Hiroaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujii, Hiroyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujita, Shinichiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanabe, Yujirou"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ito, Jun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimizu, Masami"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mabuchi, Hiroshi"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"ME-PR-MABUCHI-H-341.pdf","filesize":[{"value":"171.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-MABUCHI-H-341.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/12989/files/ME-PR-MABUCHI-H-341.pdf"},"version_id":"b74e07c6-0766-48e6-8f2b-2f2c0729a5c1"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Perfusable tissue index obtained by positron emission tomography as a marker of myocardial viability in patients with ischemic ventricular dysfunction","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Perfusable tissue index obtained by positron emission tomography as a marker of myocardial viability in patients with ischemic ventricular dysfunction"}]},"item_type_id":"4","owner":"3","path":["1134"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"12989","relation_version_is_last":true,"title":["Perfusable tissue index obtained by positron emission tomography as a marker of myocardial viability in patients with ischemic ventricular dysfunction"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:11:59.359825+00:00"}
