The purposes of this study were to evaluate the feasibility of magnetic resonance (MR) assessment of altered myocardial blood flow (MBF) in response to the cold pressor test (CPT), and to determine if coronary endothelial dysfunction in young smokers can be detected with this noninvasive approach. Fourteen healthy non-smokers (31 ± 6 years) and 12 smokers (34 ± 8 years) were studied. Breath-hold phase-contrast cine MR imaging (PC-MRI) of the coronary sinus (CS) were obtained at rest and during the CPT. MBF was measured as CS flow divided by LV mass and the rate pressure product. In non-smokers, MBF was 0.88 ± 0.19 ml/min/g at rest and significantly increased to 1.13 ± 0.26 ml/min/g during the CPT (P = 0.0001). In smokers, MBF was 0.94 ± 0.26 ml/min/g at rest and 0.96 ± 0.30 ml/min/g during the CPT (P = 0.73). MBF (MBF during the CPT − MBF at rest) was significantly reduced in smokers compared with non-smokers (0.02 ± 0.20 ml/min/g vs. 0.26 ± 0.18ml/min/g, P = 0.005). The intra-class correlation coefficient between measurements by two observers was 0.90 for MBF. A significant reduction in MBF response to CPT was demonstrated in young smokers with PC-MRI at 1.5 tesla. This noninvasive method has great potential for assessment of coronary endothelial function.","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文/Department of Radiology, Matsusaka Central Hospital, 102 Kobou, Kawai, Matsusaka, Mie 515-8566, Japan","subitem_description_type":"Other"},{"subitem_description":"31p","subitem_description_type":"Other"}]},"item_7_dissertation_number_60":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"乙医学第966号"}]},"item_7_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_7_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s10554-014-0387-y","subitem_relation_type_select":"DOI"}}]},"item_7_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_7_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"The International Journal of Cardiovascular Imaging volume 30, pages 73–80 (2014)に掲載"}]},"item_7_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Doctoral Dissertation / 博士論文"}]},"item_7_version_type_15":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ichikawa, Yasutaka","creatorNameLang":"en"},{"creatorName":"イチカワ, ヤスタカ","creatorNameLang":"ja-Kana"},{"creatorName":"市川, 泰崇","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-12-09"}],"displaytype":"detail","filename":"2013DM036.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"2013DM036","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/14423/files/2013DM036.pdf"},"version_id":"183d8ece-6dec-4e80-8c1c-cab349cb24a6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Coronary endothelial function","subitem_subject_scheme":"Other"},{"subitem_subject":"myocardial blood flow","subitem_subject_scheme":"Other"},{"subitem_subject":"cold pressor test","subitem_subject_scheme":"Other"},{"subitem_subject":"Magnetic resonance imaging","subitem_subject_scheme":"Other"},{"subitem_subject":"smoking","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Altered coronary endothelial function in young smokers detected by magnetic resonance assessment of myocardial blood flow during the cold pressor test","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Altered coronary endothelial function in young smokers detected by magnetic resonance assessment of myocardial blood flow during the cold pressor test","subitem_title_language":"en"}]},"item_type_id":"7","owner":"16","path":["620"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-12-09"},"publish_date":"2021-12-09","publish_status":"0","recid":"14423","relation_version_is_last":true,"title":["Altered coronary endothelial function in young smokers detected by magnetic resonance assessment of myocardial blood flow during the cold pressor test"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-11-08T05:55:35.148159+00:00"}
