Results: A total of 732 ischemic stroke patients underwent computed tomography, 231 with transthoracic echocardiogram were included in part (1), 393 with outcome data were included in part (2). In part (1), 193/231 (83.5%) had normal LVEF (median 61%) and 38/231 (16.5%) decreased LVEF (median 39%). The low-LVEF group had significantly prolonged SO-EndAIF compared with normal-LVEF group (mean of 39.7 versus 26 second; P<0.001), and larger hypoperfusion lesions (94.9 versus 37.6 mL; P<0.001). SO-EndAIF time was strongly associated with EF, with an area under the curve of 0.86. Twenty nine seconds was the best threshold to distinguish between normal and impaired EF (area under the curve, 0.77). In part (2), the SO-EndAIF ≥29 second group had larger hypoperfusion volumes (21.8 versus 89.7 mL; P<0.001) and infarct core (12.2 versus 2.3 mL; P<0.0001) and patients with SO-EndAIF ≥29 seconds had fewer excellent or good clinical outcomes (modified Rankin Scale score 0–1; 40% versus 22%; OR, 2.79; P<0.001, modified Rankin Scale score 0–2; 65% versus 35%; OR, 1.41; P=0.033). Conclusions: AIF width correlates with ejection fraction in acute ischemic stroke. A 29-second threshold from scan onset to end of AIF accurately predicts reduced LVEF and identifies patients more likely to have worse outcomes after stroke.]]> Wed 17 Nov 2021 16:29:40 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44396 Wed 12 Oct 2022 12:58:24 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47020 Tue 13 Dec 2022 12:44:23 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33726 Thu 28 Oct 2021 12:36:19 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38503 Thu 18 Nov 2021 09:53:11 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33725 Thu 13 Jan 2022 10:30:08 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47376  1.2, and mismatch volume > 10 mL on follow-up imaging. Patients were divided into PTM or non-PTM groups. Ischemic core and penumbral volumes were compared between baseline and follow-up imaging between the two groups, and collateral flow status assessed using CT perfusion collateral index. Results: A total of 25 patients (14 PTM and 11 non-PTM) were enrolled in the study. Median core volumes increased slightly in the PTM group, from 22 to 36 ml. There was a much greater increase in the non-PTM group, from 57 to 190 ml. Penumbral volumes were stable in the PTM group from a median of 79 ml at baseline to 88 ml at follow-up, whereas penumbra was reduced in the non-PTM group, from 120 to 0 ml. Collateral flow status was also better in the PTM group and the median collateral index was 33% compared with 44% in the non-PTM group (p = 0.043). Conclusion: Multiple patients were identified with limited core growth and large penumbra (persistent target mismatch) > 16 h after stroke onset, likely due to more favorable collateral flow.]]> Thu 06 Jul 2023 13:43:31 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33106 0.05).
