A Comparison of VerifyNow® with PlateletMapping® -Detected Aspirin Resistance and Correlation with Urinary Thromboxane

BACKGROUND:Aspirin-resistant platelet activation in whole blood is attributable to a transcellular pathway not detected by isolated platelet aggregometry. Aspirin resistance as defined by urinary thromboxane levels is associated with increased risk for myocardial infarction or cardiac death. Whole b
