Changes in platelet survival with different aspirin doses (0, 2, and 30 mg/kg) before and 6 to 8 weeks and 28 to 32 weeks after placement of aortic prostheses. Significant interaction (p < 0.05, indicated by asterisk) on the basis of aspirin dosage was seen in both postoperative time periods. No significant interaction was noted preoperatively.
