Reversing Ticagrelor's Effects With Fresh Platelets


ACS patients treated with antiplatelet drugs who require CABG surgery have to wait 5-7 days for the effects of the drugs to wean off. This treatment-devoid period leaves the patient vulnerable, therefore any means to shorten this period could be useful. The present study aims to investigate the possibility of reversing the antiplatelet effects of ticagrelor with the help of fresh donor platelets. Fresh platelets will be added to blood samples of treated patients in varying concentrations at specific timepoints to determine the time and amount of fresh platelets needed to normalize platelet reactivity in the treated samples.
