To clarify the effects of stressor type on TID and post-stress LV dysfunction, changes in LV measurements were compared between patients with exercise- or vasodilator-induced stress.  Methods and Results: The 689 patients referred for technetium-99m tetrofosmin myocardial perfusion imaging were included. Patients were stressed with either a vasodilator (n=236) or exercise (n=453). LV measurements were obtained with ECG-gated SPECT. LV end-diastolic and end-systolic volume indexes (LVEDVI, LVESVI) increased and LV ejection fraction (LVEF) decreased after stress in the vasodilator-stress group. Vasodilator-stress and the summed difference score (SDS) were independent variables that decreased LVEF after stress. Even in patients without reversible defects, vasodilator-stress impaired LV function. There were no differences in the stress-to-rest ratios of LVEDVI (rEDV) and LVESVI (rESV) among patients with normal myocardial perfusion, fixed defects and reversible defects in the vasodilator-stress group, whereas in the exercise-stress group, rESV was significantly higher in the patients with reversible defects than in those without reversible defects. Within the vasodilator-stress group, neither rEDV nor rESV correlated with the SDS.  Conclusions: Vasodilator-stress by itself decreases LVEF after stress. TID should be carefully interpreted when vasodilator-stress is used to detect severe CAD.","subitem_description_type":"Abstract"}]},"item_3_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"THE JAPANESE CIRCULATION SOCIETY"}]},"item_3_relation_28":{"attribute_name":"出版社DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1253/circj.CJ-10-0299","subitem_relation_type_select":"DOI"}}]},"item_3_rights_7":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright 2010 THE JAPANESE CIRCULATION SOCIETY"}]},"item_3_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13469843","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_20":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"13474820","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_32":{"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":"Odagiri, Keiichi"}]},{"creatorNames":[{"creatorName":"Uehara, Akihiko"}]},{"creatorNames":[{"creatorName":"Kurata, Chinori"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-08-27"}],"displaytype":"detail","filename":"CircJ74_12-2666.pdf","filesize":[{"value":"615.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CircJ74_12-2666.pdf","url":"https://hama-med.repo.nii.ac.jp/record/2357/files/CircJ74_12-2666.pdf"},"version_id":"8af73d95-323f-40e1-9002-b6ead7132485"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Adenosine","subitem_subject_scheme":"Other"},{"subitem_subject":"Exercise","subitem_subject_scheme":"Other"},{"subitem_subject":"Ischemia","subitem_subject_scheme":"Other"},{"subitem_subject":"Left ventricular function","subitem_subject_scheme":"Other"},{"subitem_subject":"Single-photon emission computed tomography (SPECT)","subitem_subject_scheme":"Other"}]},"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":"Vasodilator Stress Impairs the Left Ventricular Function Obtained With Gated Single-Photon Emission Computed Tomography in Patients With Known or Suspected Coronary Artery Disease","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Vasodilator Stress Impairs the Left Ventricular Function Obtained With Gated Single-Photon Emission Computed Tomography in Patients With Known or Suspected Coronary Artery Disease","subitem_title_language":"en"}]},"item_type_id":"3","owner":"4","path":["11"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-08-27"},"publish_date":"2013-08-27","publish_status":"0","recid":"2357","relation_version_is_last":true,"title":["Vasodilator Stress Impairs the Left Ventricular Function Obtained With Gated Single-Photon Emission Computed Tomography in Patients With Known or Suspected Coronary Artery Disease"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-08-02T04:54:01.091969+00:00"}
