The cyclooxygenase-1 C50T polymorphism is not associated with aspirin responsiveness status in stable coronary artery disease in Tunisian patients.

In this study, we evaluate the relationships between aspirin nonresponsiveness and the cyclooxygenase-1 (Cox-1) gene C50T polymorphism in stable coronary artery disease (CAD) in Tunisian patients. One hundred twenty-five stable CAD patients were included. The Cox-1 gene C50T polymorphism was determined by the polymerase chain reaction/restriction fragment length polymorphism method.
