All LVEFs were categorized into intervals of 5% in width. The lowest and highest intervals are ≤40% and >70%, respectively. The primary outcome was all-cause death at 1 year. Cox proportional hazards regression analysis was performed to investigate the association between baseline LVEF and clinical outcomes.<h4>Results</h4>This analysis included a total of 14,053 patients. In total, 418 patients died during 1-year follow-up. Overall, LVEF ≤60% was associated with a higher risk of all-cause death compared to LVEF >60%, independent of demographic and clinical characteristics (aHR 1.29 [95% CI 1.06-1.58]; p = 0.01). The cumulative incidence of all-cause death was significantly different among the eight LVEF groups that survival declined successively with the decrease of LVEF (log-rank p ≤ 0.0001).<h4>Conclusions</h4>Patients with AIS or TIA with decreased LVEF (≤60%) had a lower 1-year survival rate after onset. LVEF 50%-60% even within the normal range, may still contribute to poor outcomes in AIS or TIA. Comprehensive evaluation of cardiac function after acute ischemic cerebrovascular disease should be strengthened."],"journal":["CNS neuroscience & therapeutics"],"pagination":["3518-3527"],"full_dataset_link":["https://www.ebi.ac.uk/biostudies/studies/S-EPMC10580366"],"repository":["biostudies-literature"],"pubmed_title":["Effect of left ventricular ejection fraction Spectrum on 1-Year mortality in patients with acute ischemic stroke or transient ischemic attack."],"pmcid":["PMC10580366"],"pubmed_authors":["Wei N","Liu X","Pan Y","Liu L","Xiang X","Wang Y","Wei Y","Nie X","Meng X"],"additional_accession":[]},"is_claimable":false,"name":"Effect of left ventricular ejection fraction Spectrum on 1-Year mortality in patients with acute ischemic stroke or transient ischemic attack.","description":"<h4>Aims</h4>We aimed to investigate the association of the left ventricular ejection fraction (LVEF) spectrum with 1-year clinical outcomes in patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA).<h4>Methods</h4>In a prospective registry for the Third China National Stroke Registry (CNSR-III), AIS or TIA patients with echocardiography records during hospitalization were recruited.
