Late in the disease, however, LV systolic dysfunction and dilatation are recognized. Although abnormalities in cardiac sympathetic nerve activity in patients with HCM have been demonstrated using 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy, the changes of cardiac sympathetic nerve activity throughout the clinical course from typical to end-stage HCM are unclear. The objective of this study was to evaluate the relationship between abnormalities on 123I-MIBG myocardial scintigraphy and pathophysiologic changes in patients with HCM. Methods: We performed 123I-MIBG scintigraphy on 46 patients with HCM and 18 age-matched control subjects. The patients were categorized into 3 groups: 28 patients with normal LV systolic function (group A), 9 patients with LV systolic dysfunction (group B), and 9 patients with LV systolic dysfunction and dilatation (group C). With planar 123I-MIBG imaging, the heart-to-mediastinum ratio for early and delayed acquisitions and the washout rate were calculated. With SPECT, polar maps of the LV myocardium were divided into 20 segments. The regional uptake and washout rate were calculated from semiquantitative 20-segment bull's-eye analysis. Results: The early uptake was significantly lower in group C than in the control group (P < 0.01). The washout rate was progressively higher in group A, group B, and group C (P < 0.01). Reduced regional early uptake was found in 2.9 ± 3.4 (group A), 4.1 ± 4.7 (group B), and 7.4 ± 4.3 (group C) segments, respectively. In group C, regional early uptake was significantly reduced, predominantly in the interventricular septal wall, and regional washout rate was increased in the apex and lateral wall. Conclusion: These results suggest that cardiac sympathetic nerve abnormalities in patients with HCM may advance with development of LV systolic dysfunction and dilatation and that 123I-MIBG myocardial scintigraphy may be a useful tool for the evaluation of pathophysiologic changes in HCM.","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":"THE SOCIETY OF NUCLEAR MEDICINE INC"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA00703684","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"01","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":"Terai, Hidenobu"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Shimizu, Masami"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Ino, Hidekazu"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Masato"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Uchiyama, Katsuharu"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Oe, Kotaro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakajima, Kenichi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Taki, Junichi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Kawano, Masaya"}],"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-TERAI-H-1612.pdf","filesize":[{"value":"119.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-TERAI-H-1612.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/12952/files/ME-PR-TERAI-H-1612.pdf"},"version_id":"2a5ba871-e288-4046-aa14-03c470eedecf"}]},"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":"Changes in cardiac sympathetic nerve innervation and activity in pathophysiologic transition from typical to end-stage hypertrophic cardiomyopathy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Changes in cardiac sympathetic nerve innervation and activity in pathophysiologic transition from typical to end-stage hypertrophic cardiomyopathy"}]},"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":"12952","relation_version_is_last":true,"title":["Changes in cardiac sympathetic nerve innervation and activity in pathophysiologic transition from typical to end-stage hypertrophic cardiomyopathy"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T09:48:13.661986+00:00"}
