The aim of this study was to find test parameters with the best potential to identify myocardial ischemia in post\u2010\n CABG<\/jats:styled-content>\n patients.\n <\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n Fifty\u2010two consecutive patients scheduled for\n CABG<\/jats:styled-content>\n , underwent both dobutamine stress echocardiography (\n DSE<\/jats:styled-content>\n ) and cardiac magnetic resonance first\u2010pass perfusion imaging (\n CMR<\/jats:styled-content>\n \u2010\n FPPI<\/jats:styled-content>\n ) with adenosine vasodilation, before and 8\u201310\u00a0months after the surgical revascularization. A pathologic biphasic stress response (\n PBR<\/jats:styled-content>\n ) expresses the presence of contractile reserve during low\u2010dose dobutamine that decreases to hypo\u2010 or akinesia provoked by high\u2010dose dobutamine. During\n DSE<\/jats:styled-content>\n , potential\n PBR<\/jats:styled-content>\n , segmental wall\u2010motion score (\n WMS<\/jats:styled-content>\n ) as well as peak\u2010systolic longitudinal strain (\n PLS<\/jats:styled-content>\n ) at peak\u2010dose dobutamine were assessed.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Post\u2010\n CABG<\/jats:styled-content>\n , there was still a relatively high prevalence of ischemia\u2010positive segments evaluated by deformation imaging, but the number of such segments was significantly lower by\n PBR<\/jats:styled-content>\n (20% and 22%) compared with peak\u2010dose strain and\n WMS<\/jats:styled-content>\n (62% and 77%, respectively;\n P<\/jats:italic>\n <.05). The use of\n PBR<\/jats:styled-content>\n instead of peak\u2010dose\n WMS<\/jats:styled-content>\n and strain could reduce the number of false\u2010positive test results post\u2010\n CABG<\/jats:styled-content>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n Among all imaging modalities tested,\n PBR<\/jats:styled-content>\n by\n WMS<\/jats:styled-content>\n and strain may be useful parameters for identifying patients with the need for new revascularization. We furthermore found that\n DSE<\/jats:styled-content>\n may be interpreted as positive when revealing at least three ischemia\u2010positive segments. The sensitivity of these test modalities for detecting coronary restenosis needs to be determined in further studies on a cohort of symptomatic post\u2010\n CABG<\/jats:styled-content>\n patients.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/echo.13471","type":"journal-article","created":{"date-parts":[[2017,2,6]],"date-time":"2017-02-06T05:37:03Z","timestamp":1486359423000},"page":"557-566","source":"Crossref","is-referenced-by-count":8,"title":["Assessment of myocardial ischemia by strain dobutamine stress echocardiography and cardiac magnetic resonance perfusion imaging before and after coronary artery bypass grafting"],"prefix":"10.1111","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9084-5805","authenticated-orcid":false,"given":"Assami","family":"R\u00f6sner","sequence":"first","affiliation":[{"name":"University Hospital North Norway Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henrik","family":"Schirmer","sequence":"additional","affiliation":[{"name":"University Hospital North Norway Troms\u00f8 Norway"},{"name":"Department of Clinical Medicine University of Troms\u00f8, The Arctic University Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amjid","family":"Iqbal","sequence":"additional","affiliation":[{"name":"University Hospital North Norway Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bart","family":"Bijnens","sequence":"additional","affiliation":[{"name":"ICREA\u2010Universitat Pompeu Fabra Barcelona Spain"},{"name":"K.U.
