Prevalence of high platelet reactivity in aspirin-treated patients referred for coronary angiography.
Aspirin (ASA) reduces adverse events in coronary artery disease (CAD) patients by inhibiting platelets. Some CAD patients have high platelet reactivity (HPR) despite ASA therapy and these individuals have increased risk of adverse events. ⋯ In a general population of ASA-treated patients referred for coronary angiography, elevated platelet reactivity is prevalent (13%) with 50% related to noncompliance and 50% related to reduced aspirin efficacy.
