C. Michael Gibson , MS, MD;

Duane S. Pinto , MD, MPH;

Joanna Ghobrial , MD, MS;

We describe the case of a patient with NSTEMI where oral clopidogrel loading prior to PCI was directly visualized on angiography, implying a very low likelihood of adequate absorption or antiplatelet effect. This observation raises the...
