Discussion In the LEADERS FREE trial involving patients at high risk for bleeding who underwent PCI, the rate of the composite primary security end stage of cardiac death, myocardial infarction, or stent thrombosis was significantly lower with the BioFreedom polymer-free and carrier-free umirolimus-coated stent than with a similar bare-metal stent. This result was powered by a lower rate of myocardial infarction primarily. In addition, the price of the primary efficacy end point of clinically driven target-lesion revascularization was considerably lower with the drug-covered stent than with the bare-metal stent.Among women with micrometastases, the 5-year price of disease-free of charge survival was significantly reduced in the no-adjuvant-therapy cohort in comparison with the adjuvant-therapy cohort . Within the node-positive, adjuvant-therapy cohort, the 5-year price of disease-free survival didn’t differ significantly between sufferers with isolated tumor cells and those with micrometastases . After adjustment for age at diagnosis, tumor size, tumor grade, and axillary treatment or simply no axillary treatment, there remained a reduced threat of events in the node-positive, adjuvant-therapy cohort as compared with the node-positive, no-adjuvant-therapy cohort .
