Abstract

Background and Purpose: Stroke etiology drives thrombus composition. We thus hypothesized that endovascular treatment shows different efficacy in cardioembolic versus noncardioembolic large-vessel occlusions (LVOs). Methods-Procedural characteristics, grade of reperfusion, and functional outcome at discharge and 90 days were compared between patients with cardioembolic versus noncardioembolic LVO from the GSR-ET (German Stroke Registry-Endovascular Treatment;n=2589). To determine associations with functional outcome, adjusted odds ratios and 95% CIs were calculated using ordinal multivariable logistic regression models adjusting for potential baseline confounder variables. Results-Endovascular treatment of cardioembolic LVO had a higher rate of successful reperfusion (85.6% versus 81.0%;P=0.002) and a higher rate of complete reperfusion after a single thrombectomy pass (45.7% versus 38.1%;P<0.001) compared with noncardioembolic LVO. Cardioembolic LVO was associated with better functional outcome at discharge (adjusted odds ratio, 1.61 [95% CI, 1.37-1.88]) and 90 days (adjusted odds ratio, 1.29 [95% CI, 1.09-1.53]). In mediation analysis, reperfusion explained 47% of the effect of etiology on functional outcome at discharge. Conclusions-These results provide evidence for higher efficacy of endovascular treatment in cardioembolic LVO compared with noncardioembolic LVO.
