Hemocompatibility related complications in Impella 5+ patients treated with Bivalirudin and dual antiplatelet therapy: a SHEAR score evaluation
Abstract
Methods
13 patients who underwent primary PCI and Impella 5+ support and were treated with DAPT and Bivalirudin. We evaluated adverse events (AEs) and hemocompatibility-related complications according to the SHEAR score.
Results
Median duration of Impella 5+ support was 14 ± 32 days. At baseline, all patients had risk for bleeding because of DAPT (SHEAR A); moreover, 2 patients suffered from thrombocytopenia. None presented risk factors for thrombosis. The highest total SHEAR score was 6 in 2 patients, three patients had a total SHEAR score of 3, three patients had a total SHEAR score of 2, 5 patients had a total SHEAR score of 1. Both bleeding and thrombotic events were most frequent within the first 48 h of support, and bleeding events had a greater role in determining the hemocompatibilty score. No patient suffered from clinically relevant hemocompatibility-related adverse events.
